Electrochemical Micromachining Performance Optimization

Abstract

Micromachined components are finding application in a variety of fields such as medical, semiconductor, and aerospace. Electrochemical micromachining (ECMM) is a technology used to realize the micro components with enhanced features and functionality. This chapter reviews the impact of cathode profile on the machining rate and accuracy. An indigenous developed ECMM setup is used with special attachment of rotating electrode. The control parameters such as machining voltage, duty cycle, electrolyte temperature, and rotating RPM were considered on improving the output performance. The interaction between the input parameters and machining speed and overcut was studied. The input parameters considered are machining voltage, duty cycle, electrolyte concentration, and cathode tool rotation. There are various optimization processes considered to evaluate the working range of control factors for the machine on output performance. In this chapter, various multi-objective optimization techniques applied in optimization of ECMM process were reviewed.
