The ultra-short pulse laser has attracted attention as an advanced tool for functionalizing surface topography, since it has high accuracy and results in little damage. In a previous study, some innovative patterns were introduced on cemented carbide surfaces, such as dimples, which are commonly used as oil reservoirs for bearings. The accuracy is not only related to the inherent features of th...

The actual significance of any definition of toughness behaviour of carbide tools depends on the existence of an interrelation between the auality as defined and the occurrence of chiuninn and uremature failure in cuttin?. V'hile at ?resent there is no ademate analvsis available and the existing classifications do not even nrovide a ?ualitatiVc. indication for tool choice, one first has to eval...

This paper deals with the characterization of three different commercial, WC-Co cemented-carbide tools in form saw blades, one group which exhibits more frequent cracking. Since properties these materials largely depend on microstructure, a detailed was carried out using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and diffraction (XRD). The SEM image analysis ...
