What Is Electrical Discharge Machining[EDM]?

An Overview

In this comprehensive article, we will delve deep into the fascinating world of Electrical Discharge Machining (EDM). Starting with its rich history dating back nearly 80 years to 1943, when the Lazarenko couple at the Soviet Academy of Sciences invented the world's first practical EDM device, we will explore the principles, processing conditions, and various types of this groundbreaking technology. This article aims to provide a thorough understanding of EDM, shedding light on its advancements, applications, and significance in modern industries.

EDM, or Electrical Discharge Machining, is a non-traditional metal fabrication method that utilizes electrical pulses to generate sparks in a specialized liquid medium. These sparks create an electrical erosion effect that is used to selectively remove metal material from a workpiece, resulting in high-precision machining. This innovative process effectively converts electrical energy into thermal energy and finds wide applications in the manufacturing of precision components that require exceptional accuracy and surface quality.
