ELECTROCHEMICAL MACHINING OF ADVANCED MATERIALS - A REVIEW

Abstract

For electrochemical machining (ECM) to be stable and accurate, the electrolytic flow field is essential. To improve the flow field, numerous studies have been conducted. This review study offers various enhancements to aero engine blade flow approaches. This report illustrates three different flow field models: one where the solution of electrolyte is introduced at the starting and trailing edges, another proposal that takes into account the effect of gravity on bubbles according to the bubble dynamics analysis, and the final one that uses electrochemical trepanning as a method of machining to create a radial blade via a constant area. Combining modelling and investigations, the suggested methods were assessed. The outcomes of the investigation demonstrate the suitability and applicability of these flow patterns for producing aero engine parts.
