How Can We Control Precision in the ECM Process?

Abstract

Electrochemical machining (ECM) technology has witnessed several research and development breakthroughs since its introduction in early 1900s. The ECM process serves as one of the key production processes in aerospace, die-moulds, tooling and automotive industries. Over time, the demands on precision have increased and this has resulted in several developments focusing specifically on improving precision in ECM processing. However, the existing review papers have not extensively focused on the methods and parameters controlling precision in the ECM process. Therefore, this article reviews the aspects of precision of ECM processes. This article will serve as a quick-read reference for researchers/engineers looking for precision ECM. An attempt is made to answer the main question posed by industry and academia “How can we control precision in the ECM process”?
