Finite-element-analysis of the effect of different wiper tool edge geometries during the hard turning of AISI 4340 steel

This paper investigates the performance of different wiper tool edge geometries in machining of AISI 4340 steel using finite element method (FEM) simulation. The cutting process is simulated with Arbitrary Lagrangian-Eulerian (ALE) approach in AdvantEdge. The purpose is to explore the effects of wiper tool geometries on cutting performance of AISI 4340 steel compare with conventional tool. We explored the cutting force, residual stress, Mises stress and distribution of temperature, and the chip shape also be examined. The simulation results suggest that wiper tools can increase cutting force and peak cutting temperature compare with experimental result, but it can reduce the temperature of distribution in the cutting edge which is beneficial to reduce the wear of tool. At the same time, the wiper tools also have a great influence on chip shape and stress.
