In this paper, machining of hard material High Carbon High Chromium (HCHCr) die steel using Electrical Discharge Machining (EDM) with a Copper-tungsten electrode by using Tagughi methodology has been reported. The Taguchi method is used to formulate the experiment format, to analyze the effect of each control factors on machining characteristics, and predicts the optimal EDM control factor such as Servo voltage, pulse current, pulse duration and interval time. It is found that these control factors have a significant influence on machining characteristics such as material removal rate, electrode wear and Surface roughness. In order to see the impact of control factors on quality characteristic, number of experiments were conducted and. results were analyzed by Taguchi methodology and analysis of variance (standard analysis). The effect of control factors were examined for obtaining optimum surface roughness. The analysis of Taguchi method reveals that, peak current, servo voltage and pulse duration have significantly affected the surface roughness.

Abstract


In this paper, machining of hard material High Carbon High Chromium (HCHCr) die steel using Electrical Discharge Machining (EDM) with a Copper-tungsten electrode by using Tagughi methodology has been reported. The Taguchi method is used to formulate the experiment format, to analyze the effect of each control factors on machining characteristics, and predicts the optimal EDM control factor such as Servo voltage, pulse current, pulse duration and interval time. It is found that these control factors have a significant influence on machining characteristics such as material removal rate, electrode wear and Surface roughness. In order to see the impact of control factors on quality characteristic, number of experiments were conducted and. results were analyzed by Taguchi methodology and analysis of variance (standard analysis). The effect of control factors were examined for obtaining optimum surface roughness. The analysis of Taguchi method reveals that, peak current, servo voltage and pulse duration have significantly affected the surface roughness.
