INSTRUM TS Vol. 5 No. 2 2023 Introduction Under intensification of market production, there is a desire to reduce energy, material and human resources, which requires an increase in the efficiency of technological equipment to a large extent by choosing the most rational technical characteristics. This trend, aimed at increasing energy and resource saving, due to the use of modern high-performance machine tools with the necessary level of production flexibility, leads to an increase in the competitiveness of high-quality products [1–18]. The use of equipment with a capacity margin that is insufficient or exceeds the required one reduces economic efficiency, increases the level of capital costs, which leads to an increase in the cost of production [19, 20]. One of the main vectors for the development of modern mechanical engineering is the development and creation of high-tech equipment. So in machine-tool building, the leading engineering industry, high-tech equipment is complex metal-cutting systems [21–32], the construction of which is based on the principle of multifunctional integration [5, 7, 17, 21, 33–46]. One of the ways to increase the technological potential of metal-cutting equipment [1, 5, 17, 21, 24, 26, 27, 38, 42, 44] is the integration of several technological operations on one hybrid machine (for example, preliminary milling + surface hardening + fine milling , abrasive grinding + surface hardening, turning + hardening + ultrasonic hardening and finishing, turning + hardening + diamond burnishing [28, 31, 37–64]) (Fig. 1), which makes it possible to ensure autonomous operation of individual pieces of equipment in flexible production. This will reduce the range of machine tools, which in turn will lead to a decrease in the area of workshops and enterprises as a whole [1, 5, 7, 17, 21, 38, 62]. Solving production problems with the use of such equipment will be less resource-intensive, and, in addition, will lead to a reduction in the production cycle for the manufacture of machine parts. In the typical process of parts manufacturing, individual operations (surface-thermal hardening and machining) are carried out on different equipment and in different areas of the workshops, which contributes to the appearance of significant errors at each stage of the technological process: deformation of the material during heat treatment, chucking error and others on each piece. All this leads to the need to assign large б Fig. 1. Typical manufacturing process (a) and manufacturing process with hybrid metalworking equipment (b) а
