Abstract

Setting up of the Input parameters in a multi input machining setup like the Wire Electro Discharge Machine (WEDM) also known as WireEDM is a very difficult task. This is due to the fact that the multiple measurable outputs are dependent on, most of the time, a combination of the Input variables and rarely are dependent solely on one of the input parameters. Researchers are continuously studying the relationship between the Input variables and the output responses. Machining of H11 tool steels in WEDM is and area where research has been few. Since H11 tool steel is one of the most commonly used chromium hot work steels, the author has taken up for study of the same.This work deals with the study of influence of the input parameters selected, i.e Pulse on time (Ton), Pulse off time (Toff), Peak Current (Ip) and Wire feed (Wf) on the Cutting Speed (CS) and Gap Current (GC) using Correlation-Regression analysis and ANOVA. A L16 orthogonal array based on Taguchi method was designed. The relationship was studied using ANOVA and linear regression.
