Why is leading so important a profession and what has is got to do with the competitiveness of Slovenia?
Although it is often regarded to be a soft skill, the value, importance and effects of leadership and leading can be founded in measurable data. How good are we in leadership in Slovenia and what kind of organisation systems are we operating in? Why has human capital management become as important as financial capital management and why did it take so long? What are the biggest challenges we are facing and what can management do to lift Slovenia on the global competitiveness scale?

Three Young manager awards have been won by engineers. Coincidence?
Every year, the section of young managers with the Manager\'s Association of Slovenia seeks those among their colleagues in profession who became recognisable for their excellence in management and exceptional results very early in their manager careers. There is no success in today\'s business environment without innovation, so we managers are required to have a sophisticated feel for innovation pertaining both to technology and to business models. It is therefore no surprise that the nominees and winners of this award include an increasing number of managers with engineering education.

Female engineer of the year: raising the visibility and reputation of engineers in the society
\"One of the many reasons for the underrepresentation of women in technical professions is us doing a terrible job explaining how the engineers contribute to the society and its development. The current narrative about engineering is unappealing to many smart and gifted young women,\" says Canadian professor of mechanical engineering Dr. Mary Wells.
That there are not many role models for young girls in their engineering career path has also been established by the rare women of their generations who opted for a professional path in engineering. Although there are exist no rational reasons today to view engineering solely as a male profession, almost a half of the talent pool – girls interested in maths, physics and natural sciences – remains untapped.
This year, the Female and Male Engineers project in collaboration with the IRT Forum and Siemens Slovenia is going to address for the first time the challenge of invisibility of female engineers, and thereby indirectly also the visibility of engineers in the society. The Female Engineer of the Year award will be presented for the first time in January 2019, aiming to present 10 female engineers to Slovenian audience every year.

TOOL- AND MOULDMAKING – trends in 2018 - Digitalisation or Tooling 4.0
It is hard to argue against the claim that the development of technologies has never been as intense and efficient as in the latest period of the human history. One could ascertain that there are no more limits to technology. Tool- and mouldmaking is an important part of this development dynamics, creating technological innovation and implementing the technical progress in own processes of development and manufacturing of tools for the mass production.
ISTMA is a global umbrella organisation for the tool- and mouldmaking sector, always interpreting the key indicators of our sector and representing its members in other structures and institutions. Tool- and mouldmaking is a global industry with a global interest. Its development is of strategic importance for any advanced economy, so most national associations closely monitor the development of this industry and develop system incentives for its sustainable development. Tool- and mouldmaking is global both with respect to sales and with respect to the key system problems which are being solved using very similar means.
Slovenia is a tool- and mouldmaking country and a prominently export-oriented economy. This means that it remains competitive through adequate developmental and technological know-how and efficient technological realisation. Tool- and mouldmaking is a part of the smart specialization programme and an important driver of the new upturn of Slovenian economy. Let us do our best so that this shining light never fades.

Analysing the technological influences on the manufacturing precision of in-wheel electric motor components
The Elaphe electric motors are installed in the wheels of electric vehicles, so they must provide high torque for direct transmission, enable the control of individual wheels, and operate with a high efficiency rate (> 93 %). To achieve these goals, the components must be manufactured according to strict tolerance requirements, which may pose some issues in the process of manufacturing rotor components involving thin-walled and large-diameter workpieces. The forces involved in clamping and machining may significantly influence the dimensional and geometrical accuracy. Therefore, a measurement system was developed for the purposes of the study, enabling the measurement of cutting forces and deformations of thin-walled workpieces during the turning process. After machining, the manufacturing precision was determined using a coordinate-measuring machine. It was found out that deformations due to machining remain inside the acceptable limits. However, residual stresses in the material are causing a state of stress which influences the product accuracy. Based on these results, an intermediate annealing process was proposed in order to remove the internal stresses before the finishing, and a comparison of geometrical and dimensional accuracy depending on the technological parameters was made.

Automated aluminium casting manufacturing line
In the last years, the Ljubljana LTH Castings d.o.o. plant has devoted a lot of attention to automated processing of aluminium castings. So far, the process automation was focused above all on material handling for casting machines and machine tools, and line distribution of products to manual workplaces. Following our wish to further improve the already high degree of automation, we set-up last year an automated line including the handling for specialised aluminium product quality control machines. In our contribution, we are going to present the last project where we made a step further with virtually fully automated manufacturing of an aluminium product, from creation to shipping. We will describe in detail the automated line including the machining, washing, dimension control, tightness test and final packaging processes for this aluminium product. The line incorporates 5 robotic cells with 7 industrial robots, and the products are transported through the processes using a palette line. Considering that we have gathered a lot of know-how and experience in automation during the years, the complete automation line will be made in-house by our process automation department.

Hydraulic cylinders for auxiliary drives in the moulds for die casting of aluminium and for injection moulding
The most advanced developmental processes follow the main global developmental concepts, which demand: (1) the realization of circular economy concepts, lowering the energy consumed per unit of product, relieving the burden on the environment by reducing the emissions and other environmental influences, lowering the usage of material resources and so forth. The toolmaker as the last link in the development chain significantly influences the efficiency of realization of technological development and thereby the principles of sustainable development. The presentation of technological innovations in hydraulic drives will significantly influence the efficiency of developmental solutions, above all opening new possibilities for the realization of kinematics of the main components of system in the mould\'s parting plane.

Screwing with collaborative robot
The Industry 4.0 already knocks on the door and we decided that it is time to go one step forward with collaborative robot and smart automatically screwing stations.
In our company we have many stations, which include manual manipulation with screwing. Because of this we decided that it is time for something new. We made the first step and chose the robot, the second step was choosing screwing tool and the third step was to explore what is needed to make application safe. For making application safe we cooperated with company that is expert in safety systems. The last step was to combine everything together and make application with collaborative robot. The complete collaborative work station contains collaborative robot with automatically feeding screwdriver and sensors for additional safety.
With this first collaborative work station, we knocked down the fence between robot and worker and now the worker cooperates with robot and this is the new look at the industry 4.0.

Optimization of the process parameters for stabilization and improvement of the turning capability
The paper deals with a narrow tolerances turning process. A statistical process control (SPC) on the existent machining process showed that the process was not stable and incapable. Before the machining process analysis a measurement system analysis (MSA) of the applied measuring system has been performed. In order to stabilize the process the machine tool linear axis calibration has been performed. The stability and capability of the machining process increased but the problem of the roundness was still present. The possible process parameters, which could affect the roundness, were examined with the design of the experiment methodology (DOE). The results showed that the clamping force has the largest effect. Therefor a new clamping fixture was suggested to eliminate the roundness problem.

Leash for walking dogs
The inventors of this product have ensured the walking of dogs to be a much more freer experience with Lishinu. After 41 years, they have shaken up the market with this new and innovative leash. The leash is not necessary to hold in your hand, but attaches to the wrist, like a watch. Integrated is a patented »autolock« system, which intuitively allows for the movement of man and dog. The autolock system allows that the user’s palms are always free. With a decisive move, the system automatically activates, upon which a sound can be heard, which warns the dog of its undesired behavior.

Innovative Tooling Solutions
FRANKEN, a member of the German group of companies EMUGE-FRANKEN, has begun the development of circle segment cutters in 2010 and the first products were presented in 2012. The new cutter line enabled faster pre-finishing and finishing of free-form surfaces and an improved surface finish.
The workpiece surface quality depends on two parameters – tool radius and axial depth of cut (ap). The surface quality is reduced with a greater depth of cut and improved with a greater tool radius when the axial depth of cut stays the same. Imagine that a certain surface roughness requires a 500-mm cutter and, consequently, a working space large enough to accommodate a 1000-mm diameter tool. That would be simply impossible.
How to solve this problem?
FRANKEN as the pioneer of circle segment cutters has found a solution and upgraded its circle segment cutter program in 2017 with two new shapes. The development, operation and advantages of the new cutters will be presented at the forum.

Robotization of a forging line
UNIOR d.d. has realised the robotization of a second forging line for automotive engine connecting rods. The forging manufacturing process consists of several operations, and the robots are included downstream from the forging machine. This machine is still human-operated, and then the forgings are moved by robots first into the trimming press, then into the calibrating press, and finally onto the cooling conveyor. The paper will describe the main components and the design of the robotized line, including some specifics due to the high temperatures and short cycles.

Integrated solutions for manufacturing process control in line with the Industry 4.0 strategy
Industrialised countries are increasingly focusing on manufacturing process optimisation with a single goal: establishing optimal, controlled and competitive production. Our longstanding collaboration with the partners from different manufacturing companies and branches of industry has made it possible for us to channel these demands, wishes and trends into the development of technologies and platforms that enable modern manufacturing companies to achieve manufacturing excellence. In line with this, we have created the Productive Process Pyramid™, where technology is used in every layer to monitor the production process and enable the companies to control their production conformance and excellence in all stages, from manufacturing process planning to final control when the products leave the factory.
All trends are clearly showing that all state-of-the-art technology available has to be integrated in a consolidated system, thereby enabling the users to simply control and manage their processes.
And this is one of the key pillars of Industry 4.0, also known as “Smart factories”.
In our presentation, we are going to highlight the technologies and their place in the manufacturing processes with respect to the comprehensive automation, optimisation and manufacturing process quality assurance in the industry.

Applications of plasma technology
Plasma surface modification with low pressure plasma, is growing exponentially as industrial engineers and manufacturers. By supplying energy, gas is ionized - therefore plasma is formed! In plasma atoms, molecules, ions and electrons move freely, interact among each other and the item which has to be treated. Its surface can be refined and modified in manifold ways. Completely new and innovative surface characteristics can be created as well improving or making already existing processing technologies more effective in an environmental friendly way. During Plasma activation functional groups are generated on the items surface to which paint- or glue-systems can bond. With a special process it is possible, to create thin layers on the surface. These layers are working as a primer system. Layers deposited can be hydrophilic, hydrophobic, decorative and protective. The resulting micro structure has a larger surface area which improves bonding of the coating by providing the coating with more adhesion locations. Industries ranging from medical and biotech, to aerospace, electronics and even consumer goods are realizing that altering the surface of their materials can yield significant benefits.

Robotic cell for stone wool stacking intended for insulation of kitchen ovens
The stone wool stack cell is mounted at the end of the production line, on which elements for insulation of different types of kitchen ovens are made. The method of making stone wool is special, and it required the development of a dedicated robotic gripper, a special type of conveyor belts, and a vision system that, in conjunction with Yaskawa robots, offers easy use of the robotic cell and handling a large number of different types of products.
Production line enables the production of large volumes of stone wool and a quick transition to a new type of product. The customer of robot cell, Knauf Insulation supplies products of various sizes and wool densities, which are produced in large or small series. Robotization of product stacking at the exit from the press is the first and at the same time the most important step towards a fully automated packaging and palletizing process.

Innovative grinding technology in the manufacturing of automotive engine shafts
The paper presents the development of innovative grinding technologies in the manufacturing of automotive engine parts. One common feature of these technologies is that they are based on a robust temperature model, including a description of the geometry and grinding kinematics. This enables the process to be optimized with the aim of minimizing the machining time and controlling the heat damage to the workpiece. The advantages of new technologies are presented using two cases of grinding process strategies in engine manufacturing at Scania: (1) grinding camshaft cams and (2) grinding crankshaft crankpins. Both technologies have been patented and implemented in serial production.

AMPO – Additive manufacturing powder
Additive Manufacturing offers complete new possibilities for the manufacturing of complex shaped products. For the tooling industry additive manufacturing especially gives the opportunity for conformal cooling close to the surface of the part.
There are already a lot of standard materials for Additive Manufacturing available. However, for complex tooling applications the properties of these standard materials are not sufficient in regards of corrosion resistance, hardness, or wear resistance. Therefore voestalpine Böhler Edelstahl GmbH & Co KG will launch newly developed products to close this gap.

Robotized welding of reservoars for liquids using \'synchrofeed\' technology
Daihen Varstroj is one of the few manufacturers in this part of Europe that can boast of references in the automotive and motor industry as well as in the industry with large and heavy work pieces (references to products from several kilograms and up to 12,000 kg or more). In the robotization market, we are best known for our welding solutions - we have more than 160 installed robot systems through Europe. We are the manufacturing all the components that make up a robotic welding cell - robots, controllers, peripheral units, welding sources, welding torches, consumables, sensors and software.
Our current buyer deals with the development and production of complete process lines in the food industry, chemical and pharmaceutical industries. The presented robotic welding manipulation system was developed and conceived together with the customer, with the desire for high productivity and repeatability. Before the solution, the customer used manual welding technologies, which caused him difficulty in achieving higher productivity, especially in the case of repeatability and ensuring the highest quality of his products. In this case, the robotic welding manipulation system consists of two systems and each of them consists of two robots. In the first system there is one welding robot which is equipped with our latest welding technology called \\\"synchrofeed\\\" for \\\"cold and quick\\\" welding without sprays, one handling manipulation robot and two rotating positioners. The second system consists of two welding robots equipped with TIG welding equipment and one rotating positioner, which can be adjusted to welding the customer\\\'s products up to a height of 3,000 mm and a diameter of 1,750 mm.

Ensuring smooth edge in stamped edges of stator stacks
One issue often encountered in the process of winding electric motor cores is the tearing of insulation on the sharp edges of punched core laminations. Tearing is usually caused by burr, an unavoidable artefact of lamination manufacturing process. The laminations are therefore often stacked by laser welding and turning the last lamination. Unfortunately, this approach reduces the geometrical accuracy of the stack, and welding also affects its electromagnetic properties. Stacking directly in a tool using clamps usually improves the geometrical and electromagnetic properties, but doesn’t allow us to turn the last lamination. Hidria Rotomatika has therefore developed a stack post-processing technique which removes the burr in certain spots on the laminations. This reduces the risk of insulation tearing and extends the intervals between punch and die regrinding.

Additive manufacturing of polymeric moulds for small-batch production
One of trends of 4th Industrial revolution is personalised production, which is realised through production of one to few products. Application of classical production processes, for example injection moulding, requires mould making which is time consuming, and specially, in case of small-batch production, represent an economic impact on the development and production process. Direct application of additive technologies can partially decrease the drawbacks of classical approach, but additive manufacturing processes are limited with available materials and in the process physics, e.g. production layer-by-layer which is significantly different than injection moulding process. Potential solution is application of additive technologies is in production of temporary moulds for small-batch production of moulded parts from originally requested material. This approach enables large time savings, compared to classic mould production, simplification of mould and reduction of mould production costs - and costs of moulded part production respectively. Paper presents PolyJet additive process, and it\\\'s application for production of temporary moulds for injection moulding for small-batch production.

Solving complex problems in small and medium enterprises
Products offered by small and medium enterprises are becoming increasingly sophisticated, optimised and complex, and they must therefore meet an increasing number of regulations. Aiming for steady progress and process optimisation, the companies focus on the development of key properties and functions of their product, thereby becoming increasingly specialised and narrowly focused. Many product components or some technological operations are outsourced to external partners.
Problems that sometimes occur are complex, multilevel and not straightforward. It often turns out the clients do not have enough resources, experience, know-how or analytical methods to comprehensively deal with the problems and their solutions.
We are going to present two case studies where our company was involved in solving a real-world problem and finding a path to the end solution.

The influence of optical scanning on new die and product sampling performance
The die manufacturing process and product validation by the client belong among the most important steps in the Product Life Cycle, including the project planning and realisation process, die and equipment manufacturing, and production process. Modern control and inspection methods are capable of providing a significant improvement of results, eliminating rework on the dies and reducing the volume of pilot test series, thereby directly reducing the associated costs. Customer satisfaction is also improved as the volume of sampling is reduced, directly influencing the supplier assessment and bringing new orders.

Problems of moulding decorative semi-products
Automotive design is one of the key elements of car sales. In order to meet the demands of customers, designers in the field of designing sport and electric cars use solutions that are problematic from the point of view of the product manufacture. Thus, a change in traditional thinking about the design of the product and molds is required. The increasing customer demand for aesthetic product suitability and the lower tolerance for larger product dimensions cause an additional problem. Products with a large ratio of length to other two dimensions are, from the technological point of view, problematic for manufacturing. Therefore, a thorough reflection on the design of the product as well as the concept of the mold is to be done in the development stage.
The article outlines the problems of the development and optimization of molding process of the lamp\\\'s outer lens with a large dimension ratio.

Thermal properties and microstructure of enamels and enamelled steel sheets
Measurements of the thermal properties of two enamel grades, used for kitchen appliances, by transient plane heat source method Hot Disk TPS 2200 in accordance with the international standard ISO 22007-2 were performed. Since we could not perform direct measurements of the thermal properties of enameled steel sheets, samples of enamels were also prepared in the form of thick layers. The results obtained from the measurements of the thick layers are within the expected values of the enamels thermal properties. However, it has been established, that the density of the enamel layer has a significant effect on the thermal properties.
The samples of the enameled steel sheet were metallographically prepared and analyzed by scanning electron microscopy (SEM-EDS) and optical microscopy (OM). We found out that the layer of analyzed enamels has multiphase structure, consisting of amorphous regions with different chemical composition, crystalline phases and pores. From the microchemical analysis results of the enamel powders it can be seen, that certain crystalline phases in the enameled layer originate from the process of preparing enamel powders.
From the microchemical analysis of the steel – enamel phase boundary, it is evident that chemical reactions occur during the firing of the enamel at certain points on the phase boundary, whereby the cobalt diffuses into the steel.
An assessment of the influence of enamel layer thermal conductivity on the thermal transmittance of enameled steel sheet is also calculated.

Spectrophotometry - A versatile tool to investigate polymer degradation?
Polymer Degradation has a significant negative impact on properties and life time of plastic parts and is often associated with colour changes. Spectrophotomety Is more sensitive to such colour changes than the naked human eye and may allow a quantitative investigation of degradation phenomena.
We present an indicative study that compares data from spectrophotometry and mechanical and thermal testing, using samples that were subjected to repeated processing in a twin-screw extruder. Based on our results, we discuss the advantages and limitations of this method for the investigation of polymer degradation.

Measuring device for magnetic strip force measuring
In the production of gaskets for refrigerators we are using magnetic strip to ensure the sealing of the refrigerators door. As manufacturers, the strength of the magnetic tape has so far been checked only on samples by the method of measurement based on the comparative weight, which is made on a sample cut out from the magnetic strip. This is a measuring method which destroy the product to get the sample. Because of that we could have only the statistical control of the magnetic strip force but this does not allow measurement in the entire length of the magnet. We describe the development of a prototype measuring device that allows the measurement of the magnetic force without destroying the strip and can be used in the process of making or inserting the magnetic stip. This ensures 100% control and traceability of the built-in magnetic strip in a single gasket.

Using 3D-scanning and reverse engineering to develop prototype tools for motorbike fairings
Carbonin is a Slovenian manufacturer of state-of-the-art motorbike fairings. Their products are used by teams in Superbike, Supersport and Endurance world championships, German IDM, British SBK and other national championships, as well as by private customers. This means that the fairings have to be made so that they can accommodate the lights, the counter brackets… Carbonin fairings are made of glass and carbon fibre, very precisely crafted, excellent looking and above all very light. As the fairings are currently 100% hand-made and Carbonin wishes to follow the latest trends in mechanical mould production, the company has decided to launch in collaboration with TECOS a pilot project for prototype mould milling. We used the YAMAHA YZF-R6 motorbike for the pilot project. First, we used an ATOS CS 5M structured-light optical scanner to scan the motorbike’s serial fairings, and then we scanned the whole motorbike without fairing, yielding the outer dimensions and all the fairing fastening points. We used the scanned data to reverse-engineer the fairing (preserving the basic motorbike design and observing the valid regulations and requirements for race fairings in our CAD-models). The article will present the new mould manufacturing concept in detail, including all of its advantages and disadvantages.

Influence of adding Polyamide recyclate to virgin Polyamide on mechanical and thermal properties of injection moulded parts
Due to the growing awareness of the environmental impact of plastics the increased use of recycled thermoplastics is a megatrend in plastics industry. When processing thermoplastic materials, companies are faced with the challenge to use their own recyclate from production (industrial recyclate) as well as recyclate they procure from the market.. This significantly contributes to the reduction of industrial waste and may also add value to the products. However, companies are facing the challenge to use optimized processing parameters and to define a reasonable fraction of recycled material in order to reach the required properties of the final products. At the Faculty of Polymer Technology we tested in cooperation with industry how different fractions of added recycled material influence the final properties of injection moulded products.Target is to develop guidelines which amount of recycled thermoplast is still acceptable to achieve specified properties. In this paper we present corresponding results regarding PA 6, where industrial recyclate was added to virginmaterial. We also investigated the degradation of PA 6 during repeated processing and the influence of injection moulding parameters on part properties. All presented analyses were performed in the laboratory of the Faculty of polymer technology, while the products were injection moulded at the company Skaza.

The challenges and problem solving in metal casting production using optical 3D-measurements
In our presentation, we are going to analyse the sources of geometric errors in castings made using disposable moulds on the example of a cast valve housing. The ATOS 3D-measurement machine from GOM GmbH was used to detect an offset between the two halves. Cavities in the sand mold, the pattern plates and the core form were checked using 3D-scanning and comparison to the CAD-model. An error was detected in the position of the core on the pattern plate; and the core was too small, leading to variation in the thickness of casting walls and insufficient machining allowance. Measuring with optical 3D-systems is simple and provides transparent results, so it can be implemented in different steps of the manufacturing process to ensure acceptable products within a shorter lead time.

Control device
The paper presents the development of a control device for 100% control of functional dimensions. The request for production of such devices has come from an automotive parts manufacturer. Cars consist of a large number of parts, all of which must correspond exactly to the prescribed tolerances so that we can assemble the final product from them. It is an even greater challenge to enable to produce parts for one car in several parts of the world. This is also the main reason why 100% control of most car parts is required.
The article will describe the planning process for such a control device. It will begin with the presentation of the procedure going from the drawing of the item being measured with all the measured dimensions and their tolerances defined until the design of the control device. This will be followed by a presentation of development of a mechanical construction of the device. In the end, the selection of relevant measuring sensors, the development of control equipment, control program and processing of the measured data will be presented. A process for ensuring the traceability of all pieces manufactured will also be described.

Accuracy test of three-dimensional dental optical scanner
Paper presents the results of accuracy test of three-dimensional optical scanner that is usually used in computer integrated fixed prostethic constructions production in dental medicine. 3D scanning is used to obtain the data of objects geometry and transformation into digital format. This data is later manipulated in computer software, which significantly shortens the construction modelling process. Due to the field of use, the scanning process must be as simple as possible. Also, the expected accuracy is not really high, because every construction is individualized for specific patient and can be later manually adjusted by dental technician. The purpose of the experiment was to establish an overall accuracy range of a 3D scanner for mechanical engineering measuring. The paper describes the experiment, present the results, and discusses the possible causes for deviations. Also, some issues and possible solutions for accurate measuring are discussed.

Optimisation and control of decorative semi-manufactured product injection moulding process with optical requirements
With the introduction of LED technology, the requirements for the precision of semi-finished products with optical functions in the lamps have increased dramatically. In the development phase, optical measurements must be performed for each lamp, which must be in compliance with the legal requirements that must be met throughout the entire lifetime of the product. All the manufactured products must meet the statutory values for lighting products, therefore a robust and stable injection moulding process is crucial. Increased requirements for dimensional accuracy and surface quality of optical surfaces can be met only by following and implementing new methods of process optimization during product development phase and proper control of the process of injection moulding in the production phase.
The article will show an example of the optimization of injection moulding of the semi-finished product and the tool, as well as the experience with various methods of the injection moulding process control.

Visual ergonomics using corrective safety spectacles
Man acquires more than 80% of the information through sight, so visual ergonomics is extremely important at every step. Work and working conditions are often not ideal and suitable for exposed eyes, therefore the eye needs to be protected by using the appropriate and best quality corrective safety spectacles.
Our aim is to focus on human visual abilities that change slightly with the use of protection. By correctly and appropriately choosing corrective protective eyewear we will eliminate the imbalance between human individual characteristics, environment and work task. Imbalance can cause discomfort, the appearance of errors, accidents and injuries at work. Today\\\'s technology enables the use of state-of-the-art materials for the production of corrective safety spectacles that meet the most demanding standards.
Our goal is to prepare and apply reliable and innovative solutions to protect the vision system from the impact of the external environment. We focus on the integration of state-of-the-art technology in the production of corrective safety spectacles and in creating conditions that correspond to human individual visual abilities. Human visual abilities, environment and work are involved in this.
The triangle of visual ergonomics forms human characteristics (eye health, eyeglass wear, depth detection, color separation, visual acuity), environment (illumination, danger of eye damage, air quality, psychosocial factors and job satisfaction) and work (visual displays, visual display settings, workplaces organization, size, color and font contrast, rest at work and work intensity).

IoT Vision sensor compliant to OPC UA Vision CS, the communication standard for the factories of the future
Modern technologies supported by standardization enable the implementation of new manufacturing concepts and business models in the industrial setting. The path and the goals in Europe were set by Germany in 2012 through the Industry 4.0 program. An architectural model named RAMI 4.0 was also made to present the approach to Industry 4.0 in a structured way. The three-dimensional model incorporates all the Industry 4.0 building blocks that support the product throughout its life and make sure all the Industry 4.0 stakeholders are able to understand each other.
OPC UA is the most widely used standard to comply with all the requirements of the RAMI 4.0 model, enables interoperability and connects the different model levels. The structure of OPC UA is multi-level. The basic level, providing system support for the key services, is dynamically complemented with global domain standards, the so-called Companion Specifications. The domain specifications define a unified communication interface, which must be supported by every standard-compliant device. This makes it possible for the users to quickly swap devices and machines, even if they are made by different manufacturers, while the system integrators are able to quickly set-up a system and easily maintain it.
One of these domains is Vision (machine vision). The preparation of this standard is led by German VDMA. Kolektor is a member of the core workgroup preparing the standard. The first version of specification will be presented at Automatica 2018 fair, and Kolektor will use this opportunity to present the first vision sensor in the world compliant with this specification. The IoT device will be based on deep neural networks. It will be suitable for different tasks, such as detecting anomalies in the industrial environment, and will be capable of communicating in the factories of the future using the OPC UA Vision CS standard.

Biocomposite \"MADE IN SLOVENIA\" from miskantus fiber and PE-HD matrix, designed for injection molding of technical products
Natural fibers are becoming more and more interesting both for the research sphere and for industrial use. In the field of thermoplastic composites, they are established as an alternative to glass fibers, for example, for interior equipment in the automotive industry. They are made from renewable source and therefore environmentally friendly, not abrasvie during processing and provide advantages like relatively low price and high specific stiffness and strength. The most important feature for use in the automotive industry is the lower density of natural fibers, which allows the production of light-weighted products and therefore reduces fuel consumptionl. For the production of industrially useful biocomposites with natural fibers, it is necessary to use additives, which allow good interaction of natural fibers and thermoplastic matrix, dispersants and various stabilizers. With the right combination of additives and correct parameters for compounding and injection moulding, we achieve optimal properties.
In this paper we present a biocomposite from miscanthus fibers and PE-HD matrix that is designed for use in the automotive industry and can be used to make a prototype car seat component.. We tested the influence of different amount of miscanthus fibers in the biocomposite, different technologies for pretreating miscanthus fibers and various compatibilizers. Characterization of properties was carried out partly in the laboratories of the Faculty of Polymer Technology, partly in the laboratories of Kolektor. We measured mechanical and thermal properties, dynamic mechanical properties, toughness and thermal conductivity. We also tested the porosity and homogeneity of injected moulded pieces using CT images. The achieved properties show that it is possible to prepare biocomposites from low price plastic that are suitable for engineering applications.
The work was carried out as part of the Cel.Krog project - potential of biomass for development of advanced materials and bio-based products, led by the Institute of Pulp and Paper, where Kolektor and the Faculty of Polymer Technology are involved as partners.

Use of Field Programmable Gate Array (FPGA) in industrial machine vision applications
The article presents the use of the Field Programmable Gate Array (FPGA) in industrial machine vision applications. The operation of the programmable logic circuit will be presented and the FPGA structure with classical processor (CPU) will be compared. FPGA cannot perform high-level tasks, but it can perform low-level tasks and is considerably faster. We will focus on using FPGA to implement machine vision algorithms. Image processing methods which ones are suitable for executing on FPGA will be presented. Because complex image processing solutions are often required for the efficient operation of machine vision systems, which cannot be fully implemented on the programmable logical gate array, distributed processing is often used between the FPGA and the CPU. Approaches to integrate the FPGA into machine vision systems will be presented in the paper. Also, the developed solution of the transparent plastic granules segmentation, which is performed on the CPU and on FPGA, will be presented in the article. The time-consuming of segmentation will be tested on both systems and then the results will be compared.

The application of round fine centering in tool- and mouldmaking
SIBO GROUP d.o.o. manufactures polymer products in tight tolerances. In most of our products, the external form is located in one mould plate, and the core with the internal form is located in the other mould plate. This requires a precise and repeatable centering of mould plates as the mould closes. Fine centering with sliding guides posed issues due to inaccurate centering and guide wear, so we have decided to test a round fine centering system. The system proved to be a technically and economically excellent solution and we are now using it in most of our moulds. The system guarantees accurate centering of mould plates even before the mould is closed. This is especially significant for the moulds where the closing surfaces start to mate even before the mould is completely closed.
At the 10. IRT Industrial Forum we are going to present our mould solutions using round fine centering together with our supplier, who also provides us full support. Our contribution will showcase the operation of a fine centering system with roller units and its advantages compared to the other solutions on our market. We are convinced that other Slovenian toolshops will find our experience interesting too, and that it will help them to solve issues with precise centering of mould plates and dies.

Accuracy improvement in the process of determining the glass-fiber content in composite laminates
The Fiber Fraction (FF) in the composite laminate is one of the most important parameters for composite products. During design the FF is used to predict the laminate thickness, and during quality control the FF verifies the manufacturing process, and during testing the mechanical properties strongly depend on variations in the FF.
The procedure for determining the FF is prescribed by standards, such as ISO 1172 and ASTM D2584. The procedure exposes a laminate sample to elevated temperatures, at which the organic resin burns off, leaving only the inorganic glass fibers. By weighing the laminate before and after the burn-off test, the FF is determined.
At higher product optimizations, the burn-off procedure shows discrepancies in the FF determination, because it ignores the organic fibers’ sizing and the organic stitches in the reinforcement. The procedure also inadequately accounts for the moisture in the fibers and resin. Namely, the organic substances and moisture burn away during the burn-off test, yet the procedure considers these as part of the unburnable inorganic fibers. This discrepancy gives an inaccurate FF, causing the product to be considered as not manufactured to specifications, which may lead to product rejection.
The paper proposes an upgraded procedure for determining a higher accuracy FF by considering fiber sizing, stitches, and moisture in the fibers & resin. The procedure also accounts for voids in the product laminate.

Spheroidization anealling of C60 steel
The aim of the work was to examine the influence of various preliminary heat treatments of C60 steel on the process of spheroidization.
For determination of the optimal heat treatment temperatures for C60 steel, a sensitivity-to-grain growth hardenability test was performed and on the basis of the results obtained, the temperatures of hardening, normalization and spheroidize annealing were determined. The samples were then heat treated, namely hardened in brine and oil, and normalized in order to achieve different initial microstructures before spheroidize annealing. After hardening in brine, lath martensite was obtained, whereas after hardening in oil, pearlite colonies were also noticed in addition to lath martensite. In the samples, which were normalized, however, lamellar pearlite and some ferrite in the microstructure were obtained. Following the ISO 9950 standard, a measurement probe was constructed and the cooling rates in each cooling medium (brine, oil and air) were measured. The proportion of spheroidized cementite in steel samples, which were annealed for variable lengths of time in an electrical resistent chamber furnace in air, was determined by scanning electron microscopy. Metallographic examinaton showed that in the microstructure of the samples, heat treated in brine and oil, fine particles of cementite were homogeneously distributed in ferrite matrix after one hour of spheroidize annealing, while the proportion of spheroidized lamellas in the normalized sample reached around 20 % at the same time of annealing. Even after 24 hours there was no full spheroidization in the normalized sample. Hardness measurement according to Vickers method was also performed. It was established that when steel was hardened in brine and oil, hardness fell rapidly after one hour of spheroidize annealing and then slowly decreased by the time of annealing. The hardness of normalized samples, however, constantly decreased slightly by the time of annealing.

Quality inspection of knurled shafts with the use of machine vision
In this article the processes behind prototyping machine vision system has been described for inspecting the quality of knurled shafts. We introduced the field of machine vision with emphasis on feature matching algorithms SIFT, SURF and ORB. We build a prototyping system for contactless optical control of knurled quality with the use of low cost hardware and open source software. Pictures were taken by a standard Raspberry Pi CMOS camera with 5 MP resolution. Image data was processed with Raspberry Pi model 1 B+, which ran on the Raspbian operating system. Lighting system was managed with two white LED diodes with high brightness. The solution was implemented in programming language Python with standard modules and OpenCV library. For the experiments different shafts were used with knurled surfaces. Success and time delay of all three feature matching algorithms were analysed. All were 100% successful in distinguishing the good parts from the bad ones for all test cases. The fastest algorithm was ORB, SIFT was numerically most complex.

Comparative analysis of the conventional and conformal cooling system in plastic injection moulding tools
Evermore increasing demands over the geometrical complexity of injection moulded plastic parts, achieving narrow tolerances, at reduced production costs and shorter manufacturing times are the technological challenges and problems, encountered by the toolmakers and moulders. In the field of tool-making, new technological approaches are now being introduced to achieve the high-quality products in the shortest possible time, with minimal production expenses. One of these technological solutions is also presented by new or improved cooling technologies, i.e. conformal cooling, which follows the shape or profile of the mould core or cavity to perform rapid uniform cooling process for injection moulding.
The conformal channels are being adapted directly to the contour of the final product within the tooling inserts, enabling faster heat dissipation in critical geometrical areas, a more even distribution of the temperature in the tool, smaller input of residual stresses of the final product, and consequently a greater geometric and dimensional stability of the injected parts. With shorter technological cycles of injection processing it is now possible to increase the productivity operations and decrease the production costs. By using modern methods of cooling, we can obtain better quality of the finished products, while at the same time we can reduce the production costs from 30 to 40 percent.
The presented study involves the comparative analysis of the conventional and conformal cooling effects in plastic injection moulds in relation to the final quality of the injected parts. The design and layout of the conformal cooling channels are evaluated against to traditional cooling circuits (linear channels) by CAE simulations to optimize the conformal tooling insert, later on produced with the rapid prototyping technology - Direct Metal Laser Sintering (DMLS). The current work investigates the limitations and advantages of conformal cooling technology throughout an actual comparison of the mould temperatures and cycle times in relation to the optimal heat dissipation.

Polyurethane as matrix for composites
Industrial composites are typically made from glass fibres and an epoxy or polyester matrix. However, such composites are not suitable for dynamic loads with higher elongation and often suffer from insufficient compatibility with additives and reinforcements. These limitations can be resolved to a great extent by using a suitable polyurethane as matrix material. The advantages of a polyurethane matrix are a significantly improved elongation at break and the possibility to easily control crosslinking time through accelerator edition. Cycle time can be drastically shortened without sacrificing mechanical properties and cost targets. The weakpoint of the polyurethane matrix is its moisture sensitivity. Moisture causes foaming of the polyurethane matrix, resulting in drastically reduced mechanical properties.
In this article we present examples for using polyurethane as matrix material for composites. We investigate the influence of accelerator addition and subsequent crosslinking on the mechanical and thermal properties of polyurethane-based laminates.

Maintenance Management 4.0
A highly productive, profitable production must also concentrate on the automation of maintenance in order to be able to work efficiently, flexibly and sustainably. The purpose of intelligent maintenance is more than just the organization of maintenance personnel! It must analyze process data, monitor the material flow, keep spare parts in stock, coordinate maintenance personnel and, of course, document maintenance activities.
In addition, in a complex production environment with a large number of installations, it is important that the maintenance activities and experiences are documented as Best Known Methods (BKM). In order to avoid production delays, the product flow must be coordinated by intelligent planning and the spare parts management must be coordinated with the ERP system as interlinked integration.
On the basis of examples from production, this lecture will present the procedures for intelligent maintenance management.

A system for visual cutting tool control in machine tools
This paper presents an optical cutting tool control system which brings camera based measurement functions into the machine tool. The economical optical visual system will be permanently mounted inside a milling machine and the machine CNC will communicate directly with the system. The optical visual measuring system is designed to handle the tough environment of machine tools while at the same time delivering reliable measurements to the CNC control system. The visual control prototype consists of a high speed smart camera mounted on an adjustable aluminium frame, cutting tool fixture, and a controller. The controller is built in Labview. The milling tool could be measured while it is rotating at working speed. The prototype visual system measures length, radius, and geometry of all rotating cutting tools. It is especially optimized for measurement of ball and flat end mills, drills, engraving and chamfer tools. It also measures tool wear and detects tool breakage. The cutting tool is controlled by the machine tool CNC controller through simple measurement cycles and PC based control system developed in LabVIEW software. The smart cutting tool control system structure enables reliable measuring operation where the effect of oil and chips do not affect the measuring results.

Flexmould: flexible self-regulating moulds for injection moulding of polymers
Mould making is the biggest cost factor in plastic product manufacturing. In large production series, moulds and other peripheral equipment are quickly compensated. However, if the series are small, moulds become a big challenge in terms of cost, one that is often quite difficult to overcome. The trends in product design dictate an enormous growth of product variants and smaller series, where the conventional approach of making a new mould for every significant product modification proves to be a big cost disadvantage.

Tecos and Bizjan orodjarstvo tool- and mould-making company are developing a new mould concept that will make it possible to injection mould different products in a single mould. The project is co-financed through the Ministry of Economic Development and Technology program \"Innovation, research and development in value chains and networks\".
The mould will be fitted with a special actuator system and control to enable the autonomous selection of cavities and adjustment of injection moulding process to 4 products of completely different shape.
The article will present the limitations and technological challenges which had to be overcome developing the prototype of a self-regulating flexible mould. We will describe the mould concept development phase and discuss how product shape is limited by the mould concept and the injection-moulding process.
The final mould design aims for cost-efficient low-series injection moulding of completely different products.
