Coupled Simulation between Machine Tool Behavior and Cutting Force using Voxel Simulator

Abstract

Since cutting force acts on feed drive and spindle drive systems as force disturbance, feed speed and spindle speed are changed. As the results, cutting force is also changed. In this study, a coupled simulation method of the vibration of machine tool, the dynamic behaviors of feed and spindle drive systems and the cutting force is developed. Simulation results are compared with the experimental results, and it is confirmed that the vibration of the feed and spindle drive systems due to the cutting force can be simulated by the proposed method. It is also confirmed that the cutting force influenced by the vibrations can be expressed.
