Abstract

Experimental results of the machining of steel railroad wheel axles with a single-coated tungsten carbide tool of 5° negative rake angle are presented and the effects of cutting conditions on tool wear, chip formation and cutting forces are discussed. The machining was performed at relatively high speeds and feeds - much higher than those recommended by tool manufacturers - in order to increase productivity and to enhance the surface integrity of the machined component. For the cutting conditions examined: crater wear prevailed, with an insignificant amount of flank wear; semi-continuous arc-shaped chips with a spike formation on one side were formed; the tool life was rather short; the surface finish of the machined component, however, was satisfactory. © 1986.
