Abstract

Performance data were obtained for tungsten carbide, titanium carbide, and oxide tools in the finish turning of C-30 gray iron. Characteristics of typical wear patterns were examined in relation to their effects on cutting force and surface finish. Using both surface finish and tool wear as tool life criteria, the comparative performance of these tools was evaluated. The oxide tool was superior to the carbide tools except at low cutting speeds. The influence of depth of cut and of a prehoned land on the cutting edge was also studied.
