The friction coefficient in the simulation of stamping processes should be defined. Modern simulation software allows its definition as constant or its dependence on pressure or temperature. It is also useful in stamping processes to define different values in different regions, as it often reflects the nature of deformation process. This article deals with the regression and analytical models commonly used to determine the friction coefficients in specified areas of the stamping process. Analytical models were verified by an experimental strip drawing test under the same contact conditions. Steel sheets for the automotive industry were used in experiments and simulations—extra deep drawing quality DC 05 and austenitic stainless steel AISI 304. Friction coefficients were also evaluated when the cup test was performed. A regression model of drawing to the blankholding force was applied to the results. Conformity of friction coefficients when measured by cup tests and strip tests was confirmed. The values of the friction coefficient reached from the experiment were applied in FEM simulation software.

Abstract. This paper deals with assumption that simulation is the only reliable method for manufacturing and assembly systems profiling. Simulation is essential software tool that improve design and planning of complex automated manufacturing and assembly systems. Systems with high level of complexity need to be tested even before they are constructed in real manufacturing plant.

The paper presents an example of automation of the existing welding workstation exhaust system that can be similarly implemented also in other closed welding workplaces inside the buildings. The automation of previously non-automated process of exhausting the harmful chemicals and aerosols from the welding workstation create better conditions at workplace from point of view health care and safety. It also can save costs spent on the non-regulated exhaust system without decreasing the exhaust effectiveness.

Markets are already dynamic, and will continue to be so in the future. The pressure of customers / users for substantial product and service customization increases. Therefore, their demands must be met in a highly flexible, responsive and adaptable manner. The structural changes in company manufacturing systems need to be quickly adapted to the changing requirements and responded to in real-time. Production must not only be highly flexible with high-quality services, but it must be ready for work in integrated network structures. A logical response to these demands is the further development of industrial production ready for the changes presented in the forecasts of the fourth industrial revolution. In essence, it is a project of digitalization and sophistication of the industry. The new designs of highly integrated manufacturing systems and their clusters will ensure communication between the people and the means of production, as well as the production systems and other physical objects.

The aim of the work is to change the current program in the programmable logic controller (PLC) to be as close as possible to the real-world Pick to Light system in the automotive industry for installing individual car components. The change consists in completing the navigation and tutorial mode while preserving the original function of the program, which is to measure the time of each step in assembly of the components and the reading of the pieces from the trays. A simple virtual laboratory model was created which enables to test the program even if the access to the PLC and HMI panel is not possible. The partial goal was to modify the visualization of the program in the operator touch panel Human-Machine Interface (HMI). Another partial goal was to implement a new PLC program. In order to better understand the created program, the flowcharts were created and described for the main parts of the program.
