Experimental Investigation on Material Removal Rate (MRR) and Kerf Width in WEDM by Taguchi Method
Keywords:
WEDM, ANOVA, Taguchi method, Material removal rate, Kerf widthAbstract
This paper presents an effect of different process parameters on material removal rate (MRR) and kerf width in wire electrical discharge machining (WEDM). Die steel AISI D3 is used for experimental purpose due to its good mechanical and tribological properties. In this study, the experiments were designed by Taguchi method using L9 orthogonal array. The process parameters like Pulse on time, pulse off time and wire feed rate were selected as input process parameters to analyze output quality characteristics in terms of material removal rate and kerf width. Analysis of variance (ANOVA) is carried out to demonstrate significant influence of input parameters on quality characteristics. The experimental results reveals that pulse on time is significant factor affects the MRR and kerf width.
