Optimization of Pulse on time and Gap Voltage parameters for Maximum Material Removal Rate (MRR) on D3 Die Steel Using Factorial Design

Abstract

The electrical discharge machining (EDM), is one of the processing based on non-traditional manufacturing procedures, is gaining increased popularity, since it does not require cutting tools and allows machining involving hard, brittle, thin and complex geometry. EDM process is based on thermoelectric energy between the work piece and an electrode. Material Removal Rate (MRR) is an important performance measure in EDM process. Since long, EDM researchers have explored a number of ways to improve and optimize the MRR including some unique experimental concepts that depart from the traditional EDM sparking phenomenon.
The quality of the machined work-piece is greatly influenced by the cutting conditions. In order to produce parts with the desired surface finish using EDM, EDM parameters should be selected properly.
