Introduction

• Machining is one of the most important process of metal forming and shaping.
• Mostly, it is used in all manufacturing processes.
• In the convention machining processes, tool is in direct contact with work piece.
• There are many disadvantages and limitations of conventional machining like tool wear, cannot machining complex surface efficiently, gives lower surface finish etc.
• For machining hard surface through conventional machining, we required a harder tool material which is sometime uneconomical and sometimes unavailable.

Non-Traditional Machining Process

• Machining too hard material.
• Forming complex parts.
• Required better surface finish and negligible tolerance.

• Work piece is heat sensitive or temperature can change internal properties of work piece.
