In this paper, 3D Finite Element Method (FEM)-based numerical modelling of precision hard turning has been studied to investigate the effects of chamfered edge geometry on tool forces, temperatures and stresses in machining of AISI 52100 steel using low-grade Polycrystalline Cubic Boron Nitrite (PCBN) inserts. An Arbitrary Lagrangian Eulerian (ALE)-based numerical modelling is employed for 3D p...

Hard turning of martensitic stainless steel is gaining importance in all manufacturing sectors like automobile and aerospace industries. Machinability of materials depends on surface roughness, tool wear, cutting forces, specific cutting pressure and work material hardness. In this research hard martensitic stainless steel AISI 440 C and SCM 440 alloy steel was used as work materials. CBN and P...
