Finish milling dynamics simulation considering changing tool angles

Abstract

The article presents the results of the dynamics simulation and analysis for five-axis milling, considering changing angles between the tool axis and the surface normal. The 3D structural dynamics model of the milling process is described based on the finite element tool and a workpiece dynamics model. Cutting forces in three directions Px, Py and Pz for different values of the tool angle are compared. Numerical simulation results enable identification of the optimal tool’s position for increasing free-form surface milling performance (chip formation, tool reliability tool, etc.).
