Demands on process and process energy sources for the electro-erosive and electrochemical micro machining

Abstract

This article will demonstrate which demands are required from process energy sources (PES), if the non-conventional machining procedures EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) are efficiently used for the micro machining. Due to the very low working gap, the process conditions are considerably changed compared to the previous machining conditions. The well known PES-concepts can no longer be treated without paying attention to the supply parameter (feeder parameters) and the gap parameter. A very efficient machining procedure is the μ-PECM, which uses the charge reversal of double layers.
