Parametric Optimization of Wedm Using Grey Relational Analysis with Taguchi Method
نویسنده
چکیده
Wire EDM is one of the latest advanced micro-machining techniques, where a thin wire (Ǿ= 0.25 mm) of tool electrode is fed on the work piece which gradually shears off the material during the machining process. This micro-machining process may help overcome the limitations and restriction faced during conventional mechanical machining process. This paper is based on wire-EDM machining of a particular ISO standard Aluminium material. The varying input parameters are identified as Servo Voltage (V), Pulse on Time (Ton), Pulse off Time (Toff) and wire tension and the outputs response is measured and analyzed in terms of Surface Roughness (Ra). Taguchi’s method has been utilized for design of experiment followed by parametric optimization of wire EDM using GRA.
