Study of Material Removal Rate Process Parameter in WEDM

Abstract

Wire cut Electrical Discharge Machining is known as nontraditional machining process. It has broad application in complex part or geometry machining. It is known as a non-contact process. The main objective of this research work is to investigate the influence of process parameters of Wire cut Electrical-Discharge Machining in material removal rate. Die steel D3 has been selected as workpiece material for study. The process parameters are peak current, pulse on time and wire tension. In experimental analysis it was concluded that on MRR the most influential process parameter is peak current with contribution of 86.02 %. Pulse of time has 12.29 % contribution and wire tension has minimum contribution of 1.12 % with 0.57% error in the study.
