| description | The quality machined surface parts depends on the kinematics cutting process, the processing mode, structural and geometric parameters of the cutting tool, etc. Designs of face mill equipped with superhard materials for finishing surfaces are known, modes of their operation and possibilities of ensuring the required quality of processing are defined. The use of stepped face mill, in contrast to conventional designs of mills, makes it possible to ensure the formation of a machined surface with a cutting element that is placed in the radial direction at the smallest distance from the axis of the mill, and in the axial direction - with the greatest projection relative to the face mill body. 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 from the surface of the workpiece. In the work, the authors considered the process of face milling of structural materials with a single-tooth and multi-tooth face milling cutter with elastic movement of the forming knife and with its rigid fixation. As a result of the research on the improved design of the face step cutter, it was established that the elastic fastening of the forming cutting element, which is based on the relatively stationary fixed on the body of the copier, allows excluding the transmission of deformations of the cutter body when cutting with rough cutting elements. This allows you to stabilize the position of the forming cutting element and isolate it from the influence of the component of the cutting force PY, which occurs on the previous rough cutting elements and has a variable value in the sections of the contact arc of the forming cutting element with the workpiece. An improved design of a stepped face mill with elastic contact of the forming cutting element with a copier fixed on the body of the machine is proposed. The obtained results of the study confirm the possibility of improving the quality through the development of new cutter designs that would provide the necessary indicators of the microgeometry of the treated surfaces. |
