Thermal Modeling of Beryllium Copper Alloy C-17200 for Electric Discharge Machining

Abstract

The parameters which effect die sinker electric discharge machine’s material removal rate are studied over here. The material focused in this experimental study is beryllium copper alloy C-17200, and electrode/tool used for machining is made of mixture of graphite and brass on EDM model EDM4025. Material removal rate is calculated and analyzed for selected set of machining parameters. The thermal analysis plays an important role in analyzing and solving the EDM of Be–Cu in terms of heat distribution. A thermal model using simulation software ANSYS is presented in order to distinguish the influence of factors current and pulse on time in EDM process of heat circulation beside the depth and radius of machining workpiece. As beryllium copper alloy (C-17200) has many applications and because of properties that is strong oxidization resistance, high hardness and elevated wear resistance Be-Cu has extensively used in industrial application such as in dies and cutting tools, automotive and aerospace industries.
