ABSTRACT Introduction. When manufacturing critical parts from high-strength and diffi cult-to-process steels in various industries, the fi nal quality is usually formed during fi nishing operations. The effi ciency of the process is signifi cantly higher when using combined, hybrid methods of infl uencing the surface being processed. When processing some complex-shaped parts, more attention in fi nishing operations is usually paid to reducing roughness while maintaining previously achieved dimensional accuracy indicators. For this purpose, abrasive tools on a rigid base are often used, placing it in a less rigid technological system. To increase the effi ciency of the process, it is necessary to establish optimal modes of mechanical and electrochemical processing of parts. In the absence of the possibility of using industrial equipment for hybrid technologies at the initial stage, taking into account the need to modernize existing technological equipment for the implementation of the electrochemical grinding process, it is advisable to study this process by simulating it on simulator devices. The purpose of the work is to develop a device for studying and simulating the process of electrochemical grinding of conductive parts with abrasive heads on a metal bond. Research methodology. To simulate the process of electrochemical grinding of conductive parts using abrasive heads on a metal bond, we have developed a special device. It allows for the basing of the workpiece and the tool, implementation the electrochemical grinding process, its kinematic and electrical conditions: main motion, linear displacement of working bodies, mechanical and electrical modes, ensuring the necessary conditions for the implementation of the technology, and implementing a control system. Results and discussion. To determine the infl uence of mechanical cutting modes on the roughness of the machined surface of a part made of corrosion-resistant steel 0.12 C-18Cr-10 Ni-Ti, empirical studies were carried out on the designed device. Planning and processing of experimental results were carried out using standard methodology for preparing and conducting a full factorial experiment. The resulting model makes it possible to determine rational mechanical cutting conditions and evaluate its infl uence on the quality of the surface being processed.
