Abstract

Investigation of Process Parameters Contribution and their Modeling n WEDM for D-2 Tool Steel Using ANOVA

Lokesh Goyat, Rajesh Dudi & Neeraj Sharma

Wire electric discharge machine (WEDM) is a non conventional machining method to cut hard to machine material with the help of a wire electrode. Response surface methodology is used for the planning of experiments and D-2 tool steel is used as a work-piece. D-2 tool steel used in tools, punches and die industries. The main objective of this study is to investigate the significant process parameters along with the percentage contribution of each parameter. ANOVA is used to find the percentage contribution of significant process parameters. The analysis of results indicates that pulse on servo voltage have the maximum effect in single parameter compared to pulse off time and peak current during the investigation of cutting rate on WEDM for D-2 tool steel.
