This report provides metal cutting standards data for turning and boring operations covering a wide range of feeds, speeds, and depths of cut based on an eight-hour tool life. Information is included on surface finish and power requirements to aid in the selection of data from these tables. Although these standards were set up primarily for use on numerically controlled equipment, they will work just as well on conventional machine tools. (Author).
Expanded and revised to include changes and additions to metal cutting theory. Covers developments in tool materials and industrial practice over the last seven years. Describes the stresses and temperatures acting on cutting tools and explains theirinfluence on performance. Discusses tool wear which determines cutting efficiency. Details machinability and control of tool material structure and composition.
