“…(2014) comparatively studied on the effect of various process parameters for powder Electrical Discharge Machining and Electrical Discharge Machining and output characteristics such as material removal rate and tool wear rate were measured. Chakraborty et al (2012) highlights one weakness of the PCA-based UT approach and proposes the necessary modification. The effect of micro-powder on surface of EDM process is carried out by Wang et al (2007).…”

In the present research work four different work materials viz. EN24, D2, H13, P20 which are commonly use in plastic industries are considered for machining applying EDM process. Four different control parameters such as pulse on time, pulse off time, gap current, and Spark gap are considered to study the effect on the performance of responses like material removal rate, surface roughness and overcut using a square shape copper tool with lateral flushing. A well design experimental plan is used to reduce the total number of experiment following L9 orthogonal array. Based on Taguchi methodology the significant process parameters affecting the responses are identified applying ANOVA for each material. The effect of the responses with respect to the four control parameters for the four different work materials is compared through linear graphs. A well-known Grey relational analysis is carried out where the weights are calculated using entropy method to full fill the multi criteria decision making process.
