Abstract
This paper presents a systematic methodology for modeling and analysis of Material removal rate of micro wire EDM process using the Response Surface Methodology (RSM). The factors of micro WEDM process are voltage, capacitance and feed rate. The machining performance of material removal rate is response variable investigated. Experimental work carried out on metal matrix composite (LM 6- B4C /9%) with zinc coated copper wire by a standard RSM design called a Central Composite Design (CCD). To analysis the proposed second order mathematical model for material removal rate using CCD for estimating the model coefficients of three factors and it has found that influences the MRR in micro WEDM process. Based on ANOVA, the voltage, feed rate and capacitance significant effect on the MRR.
