Discussing the Measure of Improving Pyrex Glass ECDM Removal Rate

Abstract

Electrochemical discharges machining (ECDM) is an unconventional technology able to machine several non-conductive materials like glass or some ceramics. ECDM technology remains an academic application and was never applied in industrial. The limit factors are highlighted. In order to improve removal rate (MRR) of Pyrex glass ECDM material and the surface quality, many promising measures such as ultrasonic vibration, abrasive, and side-insulated electrode are discussed.
