The control of surface quality during machining is an area in manufacturing which has recently received a great deal of attention in the field of research and development. The main objective of this project is to briefly explain and clarify the fundamentals of machining, to teach the basics of numerical control machining, and to give a better physical understanding of the relation between the fundamentals of machining and the actual machining process combined with the use of computers to improve quality and productivity. A basic methodology is proposed in this research for achieving computer-assisted manufacturing processes.
