This thesis discusses the specifics that occur during processing by separating the stainless steel particles. The tool wear during turning is also considered. Certain types of stainless steels are more suitable for processing. While processing stainless steel, which is more suitable for processing, the tool wear is low. Given the large impact of surface wear of the tool blade on the quality of the final product, it is necessary to reduce the tool wear as much as possible. This can be done by knowing the wear process in the particle separation process. Machining parameters also affect the tool life. In this thesis, the shortcomings that occur during processing with different parameters are pointed out. In the experimental part, stainless steel X8CrNiS18-9 was chosen, processed by turning and the parameters of processing were selected. Different impacts on the cutting blade during processing were analyzed. The temperature of the cutting blade and the quality of the machined surface were measured after processing, and a tool wear analysis was perfomed. Based on the obtained measurements and shown images of the cutting blade, it was concluded that the cutting depth, in case of the influence of machining parameters on the heating of the cutting blade, on the arithmetic mean deviation Ra, had a significant impact on the wear of the cutting blade, The greater the processing depth, the higher the measured parameters increased.
