7.0 NON CONVENTIONAL PROCESSES

CHAPTER 7 : NON CONVENTIONAL PROCESSES

7.1 INTRODUCTION

This chapter will discuss the non-mechanical method used in the material removal
processes. The non-mechanical method is applied when the strength and hardness of the
workpiece material is very high, the workpiece material is too brittle, the shape of the part is

complex and special surface finish and dimensional tolerance cannot be obtained by onther
manufacturing process. Example of advanced machining processes are electrical-discharge
machining, laser beam machining, ultrasonic machining, electrochemical machining and

water jet machining.

LEARNING OBJECTIVES

The objectives of this unit are to :
1. define the role of advanced machining, such as EDM, Laser and Water Jet machining in

the manufacturing area;
2. explain basic knowledge of advanced machining, such as EDM, Laser and Water Jet
machining;

3. recognize the typical equipments of non-conventional processes.
