State of the art in intelligent adaptive energy-saving pulse power technology of WEDM

Abstract

Pulse power as the heart of wire electrical discharge machining (WEDM) tool determines machining quality, machining accuracy, processing efficiency, wire electrode wear, stability of machining process and energy utilization rate of WEDM. For low energy utilization rate and low automation degree of pulse power, this paper systematically analyzed the development of energy-saving technology and intelligent adaptive control technology of pulse power and pointed out its key development direction.
