The purpose of the machine described in this thesis, which is not yet fully completed, tends to both didactic and commercial purposes. The didactic purpose has already been fulfilled, since with the equipment previously procured before this thesis was planned, a wide range of functions and purposes of CNC controlled machines was studied and it was decided to construct components that can be produced. Ultimately, fully functional machine will be the fulfilment of the joint work of two colleagues in graduate school. To begin with, the production from the mid-1950s to the present day will be described, as well as the characteristics of SIEMENS control and drive components that are used as a renowned product in a wide range of production machines. The mechanical part of the electrical cabinet is designed for production in the company Elektrotehnika d.o.o. in Križevci. In the second part, the focus will be on programming and modeling tools. When presenting the programming process, the basics of the programming environment on the Sinumerik 828D control unit and the ShopTurn / ShopMill integrated environment are presented, as well as the presentation of individual steps from the CAD / CAM system SolidWorks / SolidCAM, which will be used to test correct operation. CAD / CAM / CNC chain simulation included 2.5D and 3D milling. The characteristics and possibilities of the Sinumerik 828D control unit are listed, preferably for milling purposes. The basics of manual programming (according to ISO 6983) are briefly described. In the last part of the paper, a simulation was made in the SolidCAM integrated environment within the CAD software tool SolidWorks 2020, in order to present the functioning of the CAD / CAM / CNC chain. The SolidCAM programming environment is very intuitive and significantly speeds up both the performance of daily work tasks and just the beginning of training, and the ultimate goal of the simulation is to generate G code.
