Current Research in Powder Mixed Electric Discharge Machining: A Review

Abstract

Electric Discharge Machining (EDM) is a recognized and commonly used non-conventional machining method for the manufacture of complicated shapes and the processing of particularly hard materials, which are very difficult to machine by any standard machining processes. In this process, there is no direct contact between the electrode and the work-piece, this non-contact machining technique is constantly rising from the press tool and dies the process creation Process for apps for micro-level machining. In the latest decades, several researchers have focused on enhancing machining process capability such as enhanced rates of material removal with improved surface topography. Powder mixed electrical discharge machining (PMEDM) may be a newly developed technique for improving the EDM process capabilities of the EDM process in this trend. In this paper, a broad history, mechanism of PWEDM method, and literature review are presented.
