Experimental study of process parameter for surface roughness in WEDM

Abstract

Wire cut Electrical-Discharge Machining (WEDM) is a machining process which utilizes a thin wire (around 0.18mm) for material removal. In modern machining of complex object, it plays an important role. Process parameters have great in-fluence on WEDM. MRR, SR and WT are varying process parameters. In this article surface roughness (SR) in WEDM process was analysed using Taguchi method. To val-idate the results analytical and experimental results were investigated. In experiments it was observed, when peak current value was increased, SR value also increases and in resultant a rough surface was produced. Peak current was observed as most influential parameter with contribu-tion of 82.12%.
