Abstract
Quality and productivity are two essential facets developed in present competitive global market. In the present study, wire EDM process of AISI P20 tool steel optimized the quality as well as productivity simultaneously. MRR in the terms of productivity, this can be maximized and overcut in terms of quality that can be minimized. This study highlights AISI P20 tool steel of best combination of machining parameter setting with Taguchi design of experimental technique, of WIRE EDM. The selected input parameters are pulse-on time (Ton), wire feed (f) and pulse-off time (Toff). The objective of this paper is to achieve the maximum MRR and the minimum overcut. They used copper wire of 0.25 mm diameter as a tool, and dielectric fluid was used in distilled water,; L9 orthogonal array based on Taguchi design has been used. These two responses (MRR and overcut) have been converted into signal quality characteristics for optimal process environment (optimum input parameters setting). Principal component analysis (PCA) combined with grey relational analysis (GRA) with Taguchi design of experiment techniques has been used to solve the problem.
