Optimization Of Machining Characteristics in WEDM of AISI D2 Tool Steel Using Taguchi Method

This paper presents an effective approach of optimizing machining characteristicsof AISI D2 tool steel in wire electrical discharge machining process. During experiments,the five process parameters such as wire feed, peak current, pulse on time, pulse off time and servo voltage were changed to explore their effect on multiple machining characteristics namely cutting speed and surface roughness. In this investigation, L18 orthogonal array, signal-to-noise ratio and analysis of variance are chosen for the experiments. From experimental results, it is found thatthe pulse on time affects significantly the cutting speed and surface roughness; the wire feed not seeming to have much of an influence. For validation, confirmatory experiments were performed for each of the machining characteristics corresponding to their optimal combination of process parameters.
