Abstract

The non-conventional machining methods are used for machining very hard materials and to prepare difficult shapes. Electrical discharge machining (EDM) is the most commonly used non-conventional machining processes for machining hard and brittle materials with good accuracy. Tool steel is an alloy of steel which is used for applications like die preparation, tool preparation etc. In this work, H-13 alloy of tool steel is selected for machining to find out Surface Roughness and Material Removal Rate (MRR) through EDM. It is also proposed to optimize EDM process parameters. The process parameters for optimisation are pulse on time, pulse off time, current, material removal rate and surface roughness. To optimize the process parameters Taguchi L9 Orthogonal array were used.
