Experimental Investigations and development of empirical model for gap current and cutting rate in Wire Electric Discharge Machining of AISI D2 steel
Rakesh Bhandari,  Dr. Harish Nagar
The performance of the WEDM machining process mainly depends upon the suitable selection of the appropriate machining variables. Optimization is one of the techniques used in manufacturing sectors to arrive for the best manufacturing conditions, for improving productivity of the system. The objective of the present work is to investigate the effect of various WEDM parameters like pulse on time, pulse off time peak current, servo voltage and wire feed rate on gap current and cutting rate in Machining of AISI D2 Steel. Second order mathematical model for the response characteristics using central composite rotatable design has been developed using MINITAB design statistical software. The design of experiments has been done using Taguchi’s orthogonal array L27 (35). Each experiment was conducted under different conditions of input parameters as per the L27 array. The interrelation ship of various input parameters on response characteristics has been evaluated.
