In this final thesis, the process of automation of the CNC machine work process is presented in detail. In the past, most of the work was done by humans, but since today's systems require a higher level of system quality, the work of humans has been replaced by robots, so most of it is automated. In order to achieve the required level of automation, industrial robots are used in production processes. In the first part of the final thesis, machine tools are described in detail, i.e. machining centers and robots, and their importance will be presented. The software used to realize the automation process is also described. The entire automation of this production system is based on the principle of „Pick and Place“ operation of an industrial robot. The simulation was designed in the ABB RobotSudio programming tool, which uses the RAPID programming language. Parts of the production line and the working environment were created with the help of CAD software SOLIDWORKS 2020.The CNC machine is selected according to the machines already seen in similar industrial environments. The whole process of creating the simulation is shown step by step with corresponding pictures.
