Abstract: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 precision hard turning. The Johnson‐Cook plasticity model is used to describe the work material behaviour. A detailed friction modelling at the tool‐chip and tool‐work interfaces is also carried. Work material flow around the chamfer geometry of the cutting edge is carefully modelled with adaptive meshing simulation capability. In process simulations, feed rate and cutting speed were kept constant and analysis was focused on forces, temperatures and tool stresses. Results revealed good agreements between FEM results and those reported in literature about experimental ones.

- International Journal of Machining and Machinabilty of Materials is a refereed international publication in the field of machining and machinability of materials. Machining science and technology is an important subject with application in several industries. Parts manufactured by other processes often require further operations before the product is ready for application. Machining is the broad term used to describe removal of material from a workpiece, and covers chip formation operations - turning, milling, drilling and grinding, for example. Machining processes can be applied to work metallic and non metallic materials such as polymers, wood, ceramics, composites and special materials. Today, in modern manufacturing engineering, there has been strong renewed interest in high efficiency machining.
