description: The first chapter analyzed the main ways to improve the efficiency of technological processes, and an analysis of the material to be processed was carried out, namely high-strength high-alloy steel. Proceeding from this analysis, progressive instrumental materials were considered, which make it possible to process this material more efficiently. The dependence of the tool life on the cutting speed and feed was studied, on its basis, ways to increase productivity were determined by choosing the optimal cutting conditions. In the process of cutting this material are formed confluent chip, therefore, the influence of cutting conditions and tool geometry on chip formation was considered. In the second chapter, the analysis of the initial data was carried out and the technological tasks for the design of the technological process were formed. In the third chapter, two methods of obtaining a billet were considered: rolled circular cross-section, used in the original technological process, and forging, obtained by the method of hot die forging. To determine the most efficient workpiece, a comparison was made between the machining times of the two technological routes at the roughing stages. According to the analysis carried out in the 1st chapter, a suitable cutting tool was selected for the roughing stage of machining and for finishing turning operations. Based on the machining time and tool life, the number of parts processed with one tool and the instrumental cost of manufacturing one part were calculated. A control program for 4 operations was developed in the Siemens NX computer-aided design system. In the fourth chapter, a new technological process was finally designed, including the design of a new workpiece and the development of a setting-clamping device for a milling operation. The result of this chapter was a set of design and technological documentation, placed in the appendices. The choice of a new workpiece and the optimal cutting tool made it possible to reduce the machining time of the part in roughing operations from 39min to 12min, i.e. by more than three times. This indicates the effectiveness of decisions made and the achievement of the goal of this work.
