Abstract :

Understanding the machining process at the microscopic level has been a challenge over the years. The machining process is very complex due to various factors, which are involved like friction, plastic deformation and material failure. The present works aims to develop a 3D Finite Element Model (FEM) to predict the residual stresses induced during the machining operation. Over the years, a lot of development has taken place particularly with the advent of high-end computers and FEM software packages. This work aims to incorporate the developments that have taken place recently in the field of Finite Element Analysis of machining processes and try to introduce an improved model to understand the machining process. Machining induced residual stresses were determined using X-ray diffraction method and compared with the simulation results. Present work is on AISI 1045 steel. Simulation results are in good agreement with the experimental results. Arbitrary Lagrangian Eulerian approach was used for finite element simulations. Many researchers use the orthogonal model to study most of the machining processes; 3D model enables us to see the oblique cutting process. In the present work a 3D model is used in order to be more realistic. © School of Engineering, Taylor’s University.
