Abstract

The electrochemical discharge machining (ECDM) is a hybrid nontraditional process, which precisely ideal for machining on conductive and nonconductive materials. Due to advanced technologies, miniaturized products have specific demand in most of the fields, which can easily be fulfilled by ECDM. The present study is a brief review of work done on ECDM in various fields, which comprises history, design, workpiece, electrolyte, tool electrode, input and output parameters used in ECDM. The conclusion gives a precise idea for enhancement and efficiently working with ECDM for the future research study.

Keywords: ECDM, electrolyte, applied voltage, tool electrode, material removal rate, glass, ceramic

2.1 Introduction

The machining has a special position in manufacturing industries due to its abilities, i.e., high accuracy, better surface finish, and stable particular property of bulk work material. The complex shapes can be manufactured by different machining processes [4]. The various nonconventional machining processes like abrasive jet process, laser beam process, and ultrasonic process are extensively used for machining of advanced ...
