Cutting Process Analysis for Uniform and Variable Edge Tools

Abstract:

Tool edge geometry has obvious influences on cutting tool behaviors. FEM modeling and simulation of orthogonal cutting process using uniform and variable edge cutting tools were studied with dynamics explicit ALE method. AISI 1045 steel was chosen for workpiece, and cemented carbide was chosen for cutting tool. Three sections of uniform and variable edges were chosen for analysis. Cutting forces and temperature distributions were calculated for uniform and variable edge carbide cutting tool. Simulation results show that variable edge cutting tool obtains small cutting forces. Ploughing force tends to reduce when variable edge cutting tool was used. Variable edge cutting tool reduces the heat generation and presents reasonable temperature distributions, which is beneficial to cutting life. The force and temperature distributions demonstrate the advantages of variable edge cutting tool.
