Electric discharge machining (EDM) is a competitive process to machine difficult-to-cut alloys. However, the rapid heating and cooling process in EDM may result in poor surface integrity such as white layer on the component surface. Complex phase transformations occur in both white layer and heat affected zone (HAZ) which are detrimental to product performance. This paper presents a numerical approach...
EDM induced residual stress is a great concern for product performance. Current modeling methods of EDM are limited to a single discharge. However, a single discharge simulation is far from the reality to predict the residual stress due to the accumulating effect of massive random discharges. In this study, a new modeling method accounting for massive random discharges has been developed to simulate...
