ANALYSIS OF PERFORMANCE CHARACTERISTICS OF WIRE ELECTRICAL DISCHARGE MACHINING
Keywords:
Wire-cut Electro Discharge Machining, Modeling, Analysis, Performance characteristicsAbstract
Wire-cut Electro Discharge Machining (WEDM) is a commonly used process in the manufacturing sector to machine complex shapes of electrically conductive materials. WEDM is so complex in nature that the selection of appropriate input parameters is not possible by the trial-and-error method. The selection of machining parameters in any machining process significantly affects production rate, product quality and production cost of a finished component. In this work, the effects of machining parameters, viz., pulse-on time, pulse-off time, wire tension, wire feed and dielectric flow rate on surface roughness and metal removal rate are analyzed. It is based on the empirical models developed by response surface methodology.
