Throughout the world market there is a continuous struggle for cheaper production with better quality. This can be achieved through optimal utilization of both material and human resources. Apart from this, with the advancement in technology manufacturing engineers are facing challenging problems requiring development of newer and better methods of production. The required rate of growth in manufacturing cannot be achieved through hit and trail and a scientific approach is necessary. This has attracted the scientists and engineers that manufacturing which was an art, has become a science.
