Assessments and comparison of Inconel 625 and Inconel 718 alloys from overcut in micro ECM

Abstract

Traditional drilling is still not appropriate for working with Inconel625 and Inconel718 alloys, since such metals become hard to remove substances. The aim of this article is really to evaluate the two separate metals from empirical data of the micro electrochemical machining (μ-ECM) process on overcut. The overcut was most much a concern when alloys were extracted during machining. Unconventional scientific data is derived from studies unless the authors are using the same instruments for testing the same process variables. Those process variables are chosen for evaluation, such as the volts, the chloride concentration as well as the feed rate of stainless-steel electrodes. Apart from the material removal rate and surface roughness, the overcut is one of the important response variables of μ-ECM. The best possible outcome of an overcut value of 0.021 mm has achieved by Inconel718 alloy. The effects of the overcut on Inconel alloys are compared.
