A series of experiments was conducted in high speed machining of powder metallurgy material with PCBN tools. The main tool wear mechanisms were discussed by observing tool wear morphology utilizing scanning electron microscopy (SEM) and detecting the element distribution of the worn tool surface using energy dispersive spectroscopy (EDS).The experimental results indicate that fragile breakage ...

The latter, if carried out inaccurately, may reduce the surface hardness and diminish the favourable compressive surface stresses after surface hardening. Accurate and continuous control of machining processes such as grinding or hard turning is essential in today's production control.

Proper grinding removes damaged or deformed surface material, while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in the shortest possible time.
