Characteristic investigation of electrochemical machining using quasi-solid electrolyte

Abstract

In electrochemical machining, the contact area with the electrolytic solution is processed, including unintended areas, and the processing accuracy deteriorates. Therefore, instead of the liquid electrolyte, electrochemical machining using quasi-solid gel impregnated with the electrolyte was proposed to improve the processing accuracy by limiting the current range. However, its processing characteristics have not yet been clarified. In this study, electrochemical machining was performed using the quasi-solid electrolyte of agar. The effects of melting of the quasi-solid electrolyte by Joule heat and kind of electrolyte on electrochemical machining were investigated and certain trends were discussed.
