ABSTRACT
Manufacturing can be defined as the act of transforming materials into usable and saleable end products. This means that the products must function satisfactorily and provide value for money. The cost, rate of production, availability, and quality of product are important criteria that should be considered when selecting a manufacturing process. With the increasing sophistication of many products and the increasing range of available materials, new manufacturing technologies have been developed to produce more sound and accurate components economically.
