Comparison of PM-HSS and Cemented Carbide Tools in High-Speed Gear Hobbing
September 1, 2009
This article examines the dry hobbing capabilities of two cutting tool materials—powder metallurgical high-speed steel (PM-HSS) and cemented carbide. Cutting trials were carried out to analyze applicable cutting parameters and possible tool lives as well as the process reliability. To consider the influences of the machinability of different workpiece materials, a case hardening steel and
a tempered steel were examined.
