Electrical discharge machining HOLEs on NICKEL-BASED ALLOYS

Abstract

Electrical discharge machining is one of the advanced processing technologies widely used to machine microhole. However, advances in materials engineering that lead to the production of new nickel-based superalloys require the development of new machining technologies. In addition, new sustainable EDM conditions to achieve the desired geometric quality of manufacturing holes are needed. In this study, a series of experiments of EDM drilling of holes were performed. The influence of capacitor capacity, discharge time, and discharge break time on the geometry accuracy of manufacturing holes was investigated and described.
