Machining is a ubiquitous manufacturing process with tremendous economic impact. For example, Dr. Eugene Merchant, who is a founder of the scientific treatment fo machining processes, recently estimated that approximately 15 % of the value of all manufactured components is derived from machining processes. Other estimates indicate that industrialized nations typically have machining expenditures that range from 3 % to 10 % of their GDP. In the United States, the estimates are slightly lower with annual expenditures of approximately $100B to $150B. However, despite the obvious economic importance, machining remains one of the least understood of manufacturing processes, with parameters still being set primarily by trial-and-error or possibly with the use of handbooks of empirical data.
