The influence of cutting forces study during finishing step face milling on the treated surfaces shaping processes

Abstract

The wide implementation of finishing face milling processes instead of abrasive treatment processes is explained by their high productivity and the possibility of providing processed surfaces of low roughness with the necessary microrelief. At the same time, for stepped face milling processes, unlike conventional milling processes, it is possible to ensure the necessary geometry of the cutting element that forms the machined surface. At the same time, special attention should be paid to the issues of stabilizing the position of the forming cutting element and the effect of cutting forces on the elastic impression of the tool. In the work, the authors considered the process of face step milling with a single-tooth and multi-tooth face step milling cutter. As a result of the research, the influence of the cutting forces of the rough cutting elements on the change in the position of the forming cutting element, which affects the dimensional characteristics of the processed surfaces, was established. It is proposed to improve the design of the stepped face mill to reduce the deformations of the tool and reduce the processing errors of flat surfaces. The results of the study confirm the feasibility of the necessary search for reserves to improve the quality of processing, by developing new designs that would provide the necessary indicators of the microgeometry of the processed surfaces.
