Smithells Metals Reference Book, Eighth Edition

The noted British mathematician R. Hill once described the state of metal cutting and forming operations with the statement that' it is notorious that the extant theory of the mechanics of machining do not agree well with experiment'.1 As this has largely continued to be the case, this chapter makes no attempt to review those theories. Rather, a short summary of the principal processes is provided along with a detailed list of reference recommendations. Professionals with an interest in the theory of metal cutting are referred to several of the many texts in this area. 2 5 Metal forming experts are referred to the excellent text by Altan et al.,6 although numerous texts exist in this area e.g. [7 10]. For a comprehensive manufacturing approach to the processes with many accompanying illustrations, the reader is referred to the text by DeGarmo et al.,11 or the text by Stephenson et al.12 These texts provide detailed, comprehensive illustrations of many of the processes discussed below with comprehensive supporting details.
The processes discussed in this chapter represent a very brief survey of metal cutting operations, grinding, deburring, metal forming, machinability, lubricants/coolants, and emerging non-traditional machining techniques. Although occupational safety guidelines that apply to these operations are incorporated as they are discussed, a short, concise reference section on the occupational safety standards that may apply is provided for the professional engineer to refer to as he/she reviews and selects the appropriate processes.
