Finite Element Analysis of Orthogonal Hard Turning with Different Tool Geometries

Abstract:

The finite element analysis of hard turning is a strongly investigated research topic thanks to the possible result of the simulations related to the chip morphology, tool wear process, cutting forces etc. The high precision hard turning differs from the conventional hard turning in the view of the depth of cut and feed rate. At low chip volumes, the rigidity of machine and clamping, the geometry of cutting tool play an important role. This research aims to investigate the stress and temperature development of different edge preparations by finite element method.
