The advances in cutting tools capable of operating at higher cutting speeds and temperatures may place different demands on steel which must respond to the increased deformation rates and increased temperatures. In this project the emphasis has been a finishing operation where high cutting speeds and small depths of cut are of importance, rather than heavy metal removal using slower speeds, high feed rates and substantial depths of cut. The major objectives of the work have been to determine the response of different tool/workpiece combinations for optimum performance, and to examine the potential for a predictive model in assessing the machinability of these combinations, in order to reduce extensive machinability testing in the future in the search for ideal combinations of steel, tool and cutting condition. The work encompassed three basic types of steels - low carbon, medium carbon low alloy and austenitic stainless steels, including various free cutting additives and deoxidation treatments. All of the steels were tested using coated carbide, ceramic, and cermet cutting tools.
