Abstract

This paper deals optimized model to investigate the effects of pulse on time, pulse off time and wire feed rate in EDM performance on material removal rate. Wire electrical discharge machining process is a highly complex, time varying & stochastic process. The process output is affected by large no of input variables. Therefore a suitable selection of input variables for the wire electrical discharge machining (WEDM) process relies heavily on the operators technology & experience because of their numerous & diverse range. Rough cutting operation in wire EDM is treated as challenging one because improvement of more than one performance measures viz. Metal removal rate (MRR), surface finish & cutting Width (kerf) are sought to obtain precision work. Using Taguchi experimental design, significant machining parameters affecting the performance measures are identified as pulse on time, pulse off time and wire feed rate. WEDM process parameters can be adjusted so as to achieve better metal removal rate.
