Optimization of cutting modes of machining with application of Ansys system

The article presents the results of a theoretical definition and modeling of the end milling process using a cylindrical cutter and the results of inelastic deformation of a part under various parts processing modes: the width and angle of inclination of the helical groove. Static models of the milling process in two-dimensional and three-dimensional setting are considered on the basis of finite element analysis of the interaction of the tool and the workpiece using the capabilities of the Ansys software package. As a tool, a cylindrical cutter with a diameter of 5 mm and 8 mm made of high-speed steel was chosen, and the workpiece is a shaped sheet of 1163 aluminum alloy. A table is presented of the dependence of cutting forces on variable values of the diameter and angle of inclination of the helical groove. By comparing the simulation results with theoretical conclusions and existing experimental results of other authors, the Ansys program was confirmed to be operable in modeling and analyzing deformations caused by the action of cutting forces of end milling processes.
