Abstract
Electrochemical micro-machining (ECMM) is generally used to effectively machine hard materials in mass production that are challenging to machine using the traditional approach. This process can pierce intricate contours, small or odd-shaped angles, or hollow craters in metals. The machining is restricted to electrically conductive materials. In this paper, techniques for producing micro-dimple are discussed. Producing a micro-hole is simple while a pit formation or micro-dimple formation needs a lot of study with respect to machining parameters. Optimization techniques are carried out so that form errors in creating micro-dimples are eradicated. Several researchers have studied the process and tried to improve various process parameters and factors affecting it. The paper focuses on producing a micro-dimple of 0.5 mm by varying the input parameters, namely voltage, feed rate, and duty ratio to get exceptional output response in MRR and Sa. The methods for handling ECMM and its parameters optimization using TOPSIS are shown in this paper.
