  • Abstract:
  • Electric Discharge Machining (EDM) is an alternative machining process to the traditional machining process for the precise machining complex-shaped electrically conductive machine parts. In EDM, machining is not affected by the mechanical properties of the work piece. The spark erosion process removes the material. It is commonly used in advanced industries in which precise parts of high quality are required, such as the aerospace, automobile, die manufacturing, and molds industries, to machine hard metals and their alloy. The economics of machining depends on the proper selection of EDM machining parameters, tool material, and dielectric. Dielectric fluid has a significant impact on EDM processes. The AISI 4140 steel is a chromium-manganese molybdenum grade used to make the dies for plastic injection molds and extrusion dies for thermoplastics and compression moulds. The primary purpose of this project work is to study the impact of EDM conditions (Pulse on time, peak current) on MRR and SR during machining of AISI 4140 steel. The pulse on-time peak current is a significant EDM condition that affects the SR and MRR. The SR and MRR are directly proportional to pulse on time & peak wind for Spark erosion oil (EDM oil) as dielectric fluid. Also, the prediction ability of the developed models is significant.
