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