In the thesis, we presented the process of manufacturing a serial tool for rubber injection, which is made from the lower, middle and upper molding plate. We focused on the following design panel for which we developed programs for CNC milling engraving and CNC milling of graphite electrodes. Our task was to prepare programmes and optimize processing times while ensuring surface quality and prescribed tolerances. We tested different machining strategies and calculated the milling speed parameters and parameters for maintaining surface quality for each milling machine used. We examined the programs in a virtual environment, which gives possible residues, and after all the treatments we measured the lower shape plate on a 3D coordinate measuring machine, which gives deviations from the actual 3D model.
