Involute Spline Profile Generation using Wire EDM Process

Today’s Mechanical Engineering field is growing rapidly in designing techniques to manufacture Splines and Gears. Over the decades, numerous methods and manufacturing processes have been used in making the various kinds of Splines based on various criteria, including applications, reliability, life time, processing time and manufacturing cost. This work is also carried out with the same notion of reviewing of manufacturing an External Involute Spline cutting tool using Wire Electrical Discharge Machining process and Vertical Milling Machine. Wire electrical discharge machining (WEDM) is an extremely accurate type of manufacturing process. This technique was commercially developed in the 1970s. Spline is a long flexible strip of metal/plastic/wood used to produce the curve through the known set of data points. The curved shape of strip is obtained by pulling it into the transverse direction using the lead weights or pegs.
