Analysis on Effect of Process Parameter on Performance Measurement in WEDM for Aluminum-6351.

Mechanical Engineering.

Accompanying the development of mechanical industry, the demands for alloy materials having high hardness, toughness and impact resistance are increasing. Wire EDM machines are used to cut conductive metals of any hardness or that are difficult or impossible to cut with traditional methods. The machines also specialize in cutting complex shapes that would be difficult to be produced using conventional cutting methods. Wire Electro-Discharge Machining (EDM) is a metal-working process whereby material is removed from a conductive work piece by electrical erosion. Wire EDM is used for machining of sheet metal dies, extrusion dies, prototype parts, small to medium batch size production of cams, rotors, turbine blades, tools, gears etc. This Research work focuses on finding out the optimum parameters in WEDM for machining Aluminum alloy 6351 tool. Input process parameters that are taken into consideration are pulse on time, pulse off time, servo voltage. The effect of input parameters on performance parameters such as material removal rate and surface roughness are experimentally noted and optimization of parameters. Also the use two different wire materials has to be done to find out the best wire material.
