NONDESTRUCTIVE TESTING METHOD FOR SURFACE DEFECTS OF SOLID CARBIDE CUTTING TOOLS

In this paper, regarding nondestructive testing of surface defects (for example, grinding-cracks of solid carbide cutting tools etc), we emphatically analyze post emulsification fluorescence penetrant flaw detection method and application in the field of quantity controlling for solid carbide cutting tools，and we put forward procedure process and procedure parameter of fluorescence penetrant flaw detection for cutting tools. At last, we induce and analyze appearance and distribute regulation for grinding-cracks of solid carbide cutting tools.
