Abstract
The understanding of cutting mechanism is important for the improvement of machinability of difficult-to-cut materials. Finite element method (FEM) is an effective way to study the metal cutting process. This paper establishes a finite element model of cylindrical turning of titanium alloys, and then simulates cutting force and tool temperature distribution under different cutting parameters. The simulation results show that in the high-speed cylindrical turning of titanium alloys, depth of cut has a greater influence on principal cutting force than feed rate, while the effect of feed rate on the maximum tool temperature is more distinct than that of depth of cut.
