Abstract
The term “carbide high-velocity turning,” has lately come into use to indicate higher turning speeds than heretofore have been considered economical or practical for machining steel. Turning speeds of 350 to 400 fpm were generally considered high, whereas today turning speeds for steel from 400 to 1400 fpm are actually used in production with great success. This paper deals with factors affecting turning of steel and presents measurements of chip temperatures, loads on tools, effect of chip breakers, and the effect of turning speeds on the quality of finished surfaces. Illustrations of tools in cut at surface speeds up to 2400 fpm are shown. Descriptions of instruments are included, together with references to parts now being machined in the “high-velocity turning range” in production.Keywords
