A proper understanding of the principles governing the metal cutting process is essential to lead the metal removal process efficiently and economically. Finite Element Method (FEM) has become a powerful tool in the simulation of cutting processes. This not only produces well-defined segmented chips with prominent adiabatic cutting bands, but also makes the analysis fast. The aim is to focus mainly on the determination of temperature fields generated on the surface of the chip especially in the shear zone. We performed a mesh refinement study that not only showed the dependence of mesh size on several process variables but also gave a clear idea of making a suitable choice that demonstrates a satisfactory compromise between precision and computation time.
Finite element method has gained immense popularity in the area of metal cutting to provide detailed information in the process of chip formation. This chapter presents an overview of the application of the finite element method in the study of the metal cutting process. We have briefly discussed the fundamentals of metal cutting and finite element methods, being the first to understand the applicability of the finite element method in metal cutting. Few of the critical problems related to the finite element modeling of orthogonal machining have been quoted through several case studies. This would be very useful for readers not simply because it provides basic steps for FE modeling for machining but also focuses on problems that need to be addressed in order to arrive at accurate and reliable EF simulations.
