Influence of Coulomb’s Friction Coefficient in Finite Element Modeling of Orthogonal Cutting of Ti6Al4V

The reliability of the pertinent parameters set Johnson-Cook constitutive model is highly linked with friction condition at tool-chip-workpiece interface. In present work, a study on influence Coulomb’s coefficient observables such as forces, chip thickness and curvature by FE simulation orthogonal cutting Ti6Al4V alloy has been carried out. A an Arbitrary Lagrangian-Eulerian (ALE) approach employed to simulate process for different conditions. simulated results, wide range conditions, are analyzed compared experimental results. analysis show that direct link observables. paper reveals accurate prediction optimized value in correlation values imperative.
