Paper Title
Parametric Optimization of Wire Cut Electro- Discharge Machining Process for Surface Finish and Kerf Width for H-31 Tools Steel
  Punam Dhanjibhai Dhamat,  Himanshu D Patel,  Khodu M Dhameliya

Wire electrical discharge machining (WEDM) is one of the important non- traditional machining processes. This is used for machining of difficult to machine materials and intricate profiles. Wire electrical discharge machining (WEDM) is extensively used in machining of conductive materials when precision is of prime importance. Wire electrical discharge machining (WEDM) allowed success in the production of newer materials, especially for the aerospace and medical industries. This process employed for the parts demanding higher accuracy levels with varying hardness or complex shapes. The main objectives of this study investigate and evaluate the effect of different input process parameters (pulse on time, pulse off time, servo voltage) on kerf width and surface roughness as response parameters have been considered for Each Experiment. Experimentation was planned as per Taguchi’s L9 Orthogonal array during machining of H – 31 tool steel work material. Brass wire electrode with 0.25mm Diameter was used as tool in the Experiments. By analyzing the Grey relational grade we find the optimum parameters. Confirmation test has been conducted to validate the optimized parameter.

Keywords- Wire electrical discharge machining, KERF Width, surface roughness, Taguchi method
