Abstract:
Metal removal mechanism in Electrical Discharge Machining is mainly a thermal phenomenon where thermal energy is produced in plasma channel, and is dissipated though work piece, tool and dielectric. The process is mostly used in situations where machining of very hard materials, intricate parts, complex shapes. The objective of this work is the optimization of the cutting parameters for Electric discharge machining of AISI 316 stainless steel to achieve the better surface finish using Taguchi’s methodology. Taguchi Parameter Design is a powerful and efficient method for optimizing quality and performance output of manufacturing processes, thus a powerful tool for meeting this challenge. This work discusses an investigation into the use of Taguchi Parameter Design for optimizing surface roughness generated by a EDM operation.

Keywords:EDM parameters,, Surface roughness, MRR, Taguchi method.
