| Abstract | PROF. JAYESH V. DESAI Asst. Prof. Mechanical Engineering Dept. LDRP-ITR, Gandhinagar Gujarat (India) Abstract: The wire electrical discharge machining (WEDM) is one of the latest non-traditional machining processes, based on thermoelectric energy between the work piece and wire. The performance of the process, to a large extent, depends on the tool material, work piece material &manufacturing method of the tool. A suitable selection of tool can reduce the cost of machining. The performance of WEDM is find out on the basis of Material Removal Rate (MRR), KERF Width and Surface Roughness (SR). The important machining parameters of EDM which affecting on the performance parameters are discharge current, pulse on time, pulse off time, arc gap, flushing pressure, servo voltage and wire tension. Taguchi design of experiments is used to conduct experiments by varying the parameters servo voltage, pulse on time and pulse off time. The process performance is measured in terms of Material Removal Rate (MRR), KERF Width and Surface Roughness (SR). In this research WEDM experiment using 0.25 mm diameter molybdenum wire & EN-31 tool Steel work piece has been done for optimizing MRR, KERF width, Surface finish and reducing cost of manufacturing. By using multi objective optimization technique grey relational theory, the optimal value is obtained for MRR, surface roughness and KERF width. |
