ABSTRACT

In this chapter, the main aspects of numerical models that can serve to predict the expected results of sinker electrodischarge machining (EDM) are described. These approaches will be based on the finite difference method, though the principles and instructions provided in this chapter can also be easily extended to models based on finite element method and other possible methodologies.

The main objectives of the numerical modeling of EDM processes will be defined and the fundamental equations that must be implemented in these approaches will also be defined. After that, the most common difficulties in the simulation of these machining processes and the possible solutions about these questions will be explained, followed by some conclusions about EDM modeling and simulation.
