After precise grinding n-WC/12Co coatings with diamond wheel , there is residual stress on the surface of parts ,the paper drawn conclusions about this study,it Pointed out the contents of further study ,the direction of farther study was prospected in this study too. The interaction between the abrasive grains and the workpiece was approximately regarded as ideal small-scale indentation phenomenon, it was used to evaluate the surface quality in ceramic machined processing that formation of grinding crack and its propagation process, the material removed process and the surface defects of the ceramic grinding, the cutting model proved that although the removed material is usually brittle removal, most of the grinding energy consumption was related with plastic deformation. |
