Advances in EDM Monitoring and Control Systems Using Modern Control Concepts

Abstract

The EDM process performance depends on the control of the machining gap and discharge pulses parameters. The dynamic performance of the servo control system and the controllable range of pulse power generator play important roles determining the stability, productivity, and quality of the machined surface. This paper reviews the research and development activities related to EDM process monitoring and control system in last two decades. Important research activities include different EDM gap monitoring systems, servo and pulse adaptive control systems, and application of modern control theory into the EDM monitoring and control systems.
