Studying the Force Exerted on the Tool-electrode During Machining: A Key Element for Force Feedback Micro- machining Using Spark Assisted Chemical Engraving

摘要

Research on Spark Assisted Chemical Engraving (SACE) micro-machining of non-conductive materials has progressed during the past years. Yet no closed loop control of the machining has been developed so far. This paper develops the results found where a correlation between the maximal forces exerted on the tool-electrode tip and the channel profile is found. This is a first step towards the development of force feedback control algorithms or micro-channel machining by SACE.
