Beschreibung

Laser machining is successfully applied at tungsten carbide cutting tools in order to produce intricate geometries, which cannot be generated by abrasive methods. In previous investigations it was shown that laser machining, applied to cubic boron nitride (cBN) cutting tools, initiates chemical reactions of nitride and binder material, which may form films of tool protecting hard material. This paper shows the effects of laser machining on phase composition, surface roughness, and residual stresses of cermet cutting tools. Cutting experiments with tools before and after laser machining have been executed in the form of external cylindrical turning of AISI 1045. Tool wear has been investigated and is discussed.
