The paper presents the results of studies of the parameters of rotary turning of welded joints in order to identify the optimal conditions for the implementation of this process. The design of a rotary cutter for turning and abrasive processing is developed. The designed technology of the rotary cutter for turning with a chip processor made it possible to produce and conduct experimental studies of the operating modes of the cutter for turning welded joints in accordance with the cutting plate inclination angle. It should be noted that the rotation of the cutting plate of the developed design of the cutter is carried out due to the friction forces of the chips on the front surface of the tool, and the angle of the cutting plate changes the direction of these forces. The results of this research included, among other things, the recommendations on the modes of industrial use of the cutter. The paper determines the efficiency of the developed rotary cutter for combined turning and abrasive processing. The cutting force was calculated depending on the cross-sectional area of the cut layer and the specific cutting force. The cross-sectional area of the shear layer was determined by simulating the technological process of cutting in the program Kompas-3D, version 16, in the assembly subsystem. Analytical and experimental studies made it possible to determine the dependence of the cutting force and roughness of the machined welded surface of the rotary turning on the cutting plate inclination angle, which allowed us to design and manufacture rotary cutters of a simplified construction. The final stage of the research was the evaluation of the effectiveness of the rotary cutter.
