Abstract

Electrochemical spark micromachining (ECSMM) process, an advanced machining process is investigated to understand process mechanism. The material removal mechanism in ECSMM is a complex phenomenon due to its multiphysics and transient nature. Experimental measurements of online current and voltage have been performed simultaneously. Different sequential operational stages in one single spark cycle have been identified in the light of the transient measurements. The Semiempirical electrical impedances during these identified operational stages have been formulated and compared with those derived by using measured online current and voltage data. Only the impedance results during electrochemical phase in a single spark cycle have been reported here. In case of ECS, considering the kinetics at the electrolyte and electrode interfaces, the effective equivalent circuit is derived. The charge transfer resistance in the equivalent circuit during the electrochemical phase is found by performing impedance spectroscopy using COMSOL multiphysics modeling software. For this 1-d model of the electrochemical process is developed using secondary current distribution. It is for the first time that COMSOL study has been attempted in analyzing the physics behind the material removal phenomenon mainly during the electrochemical operational phase of ECSMM. The modeled and measured impedances show close similarities.
