A Review on Effect of Process Parameter on Performance Measurement in WEDM

Mechanical Engineering

With the development of technology, the scientists and technologists in the field of manufacturing are facing more and more challenges. Technologically advanced industries such as aeronautics, nuclear reactors and automobiles have been demanding high strength temperature resistant (HSTR) materials having high strength to weight ratio. Researchers in the area of materials science are developing materials having higher strength, hardness, toughness and other diverse properties. This also needs the development of improved cutting tool materials so that productivity is not hampered. Hence the increased use of nonconventional machining methods in manufacturing continues to grow at an accelerated rate, Wire electrical discharge machining (WEDM) is one of the important nontraditional machining processes. This is used for machining of difficult to machine materials and intricate profiles. Being a complex process, it is very difficult to determine optimal parameters for improving cutting performance. 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 paper reviews the notable research work done by various researchers in the field of wire electrical discharge machining.
