Magnetic Field Assisted Micro-EDM

Abstract

Micro-EDM process has evidenced itself as a suitable micromachining process for micro-features that are difficult to be produced using conventional processes. However, special machining requirements are needed to be fulfilled for successful miniaturization of EDM process. High precision systems, generators producing small input energy pulses, flushing systems, etc., are the few special requirements. Effective debris removal has been the topic of concern for achieving high precision levels in micro-EDM and scientific community has therefore proposed several assisted micro-EDM processes. The present chapter briefs on magnetic-assisted micro-EDM process. The chapter begins with the introduction to EDM process and then elucidates on the principle of EDM and micro-EDM process. Characteristics of micro-EDM process are discussed next with subsequent discussion on working principle of magnetic-assisted micro-EDM process. The chapter finally terminates with the concluding remarks.
