Abstract
A manufacturing firm must be competitive as assessed by the level of profit, both locally and on a global basis in order to survive. About 40% of the selling price of a product can be manufacturing costs, and thus maintaining a high level of profit depends on reducing manufacturing costs. For this reason, the manufacturing industry has led the revolution in production technology. This has resulted in the development of highly effective Computer Aided Manufacturing (CAM) techniques which are treated rather comprehensively in this chapter.
