Modelling and Simulation of Machining Processes and Operations

subject

description

This chapter provides the state-of-the-art knowledge engineering and modelling techniques applied in manufacturing/machining and overviews future trends observed at a global scale. Modelling methods for machining processes and operations are classified. The chapter also highlights the multiple tasks of modelling and simulation in modern machining/manufacturing systems. The most popular techniques of numerical simulation including finite difference method and finite element method (FEM) related to mechanical and thermal problems arising in machining processes are described. Practical examples of FE models of various metal cutting operations and their importance in modern manufacturing are provided. The problems concerning the preparation of data and the determination of material constitutive models needed for accurate FEM-based simulations are outlined. Finally, advantages and disadvantages of FE simulations are specified in terms of their effective applications in metal cutting operations, taking into account different workpiece materials, cutting tools and machining conditions.
