To Analyse The Effects Of Process Parameters On Ig 26 Dd Of Ti-3al-2.5v Titanium Alloy Grade 9 On Wedm Using Taguchi Approach

WEDM is the most important machining method with which complex and complicated geometries can be easily machined. Based on exhaustive literature survey it has been found that limited work has to be done on machining of Grade 9 Titanium alloy Ti-3Al-2.5V. Grade 9 Titanium alloy Ti-3Al-2.5V plate of 150mm150mm6mm is used for experimental purpose. The input process parameters pulse on time pulse off time spark gap set voltage and peak current are investigated to check their effects on performance characteristics like gap current 26 dimensional deviation. The ranges of process parameters are selected based on the literature survey. The experiments were designed using L9 orthogonal array with variation in process parameters. In this study MINITAB 15.0 software is used for designed the number of alternative experiments. The main aim of study is to check the effect of various process parameters on performance parameters.
