Abstract

Electrical discharge and electrochemical processes belong to a group of nontraditional manufacturing processes that primarily use electricity or the effect of electricity to produce desired features by material removal. The electrical energy requirements for these processes are of significant importance as electrical energy is controlling the material removal in these processes. The processes included in this chapter are electrical discharge machining (EDM), electrochemical machining (ECM), and electrochemical hybrid techniques, namely, electrochemical discharge machining (ECDM), and electrochemical grinding (ECG). This chapter discusses these processes with the perspective of their energy efficiency.

Keywords: Electro-discharge machining (EDM), electrochemical machining (ECM), electrochemical discharge machining (ECDM), electrochemical grinding (ECG)

6.1 Introduction

Electrical discharge and electrochemical processes belong to a group of nontraditional manufacturing processes that primarily use electricity or the effect of electricity to produce desired features by material removal [1]. The electrical ...
