Abstract: Electrical Discharge Machine Die Sink is used to do subtractive machining especially on hardened materials like molds and such. The machine has plenty of process parameters that can be adjusted and balanced to achieve desired machining result. The study focuses on how these parameters can affect the material removal rate. The process parameters namely, machining current in low and high voltages, arc, machining gap and duration. The combination of the process parameters mentioned can affect the material removal rate by increasing it or decreasing its outcome. The machine used to collect data was a CHMER CM240 50MP. The collection of method is by removal of process parameter setting which yielded the least desired result, this is to improve data collection and cost management. The materials used in the study is an AISI 4340 for the workpiece and copper electrode for the tool. The top result of the experimentation was then cross examined to produce a more conclusive outcome. The applicability of the study to existing electrical discharge machine die sink can be seen from the statistical analysis and its ease of usage to actual working conditions.
