Optimizing the Process Parameters of WEDM using Taguchi Technique on P-21 die steel

摘要

Wire electric discharge machine (WEDM) plays a life sustaining performance in the fabricating industry in order to separate the laborious and unmanageable tool and die material. WEDM has the ability to generate complicated shapes with high preciseness and accuracy. Using the material P-21 in the existing work study finds out the application in making die tool. Present main objective of this investigation is to get parameters of the process for characteristics of single response. Taguchi method of orthogonal array L18 is used to find out desired value of performance characteristics. Investigation are done out on P-21 mould steel as work piece and tool electrode as brass wire coated with zinc. Parameter of response in material removal rate. A continuous investigation on a set of three trials is conducted and average of three continuous experiment is chosen with best condition. Using different input variable such as Input current, pulse on, pulse off, wire feed and wire tension are conducted in the investigation. After all that a confirmation experiment has to be carried out to formalize effectivity of proposed optimal condition.
