Paper Title:
The Formation and Control of Surface Cracks in the Cemented Carbide Materials in the Process of Grinding
  Abstract

As the common materials of making cutting tool, the cemented carbide has been widelyused in all kinds of mechanical machining. Based on the manufacturing craft of the brazing welded cemented carbide cutting tools, according to the theory of engineering mechanics and fracture mechanics, the main factors are analyzed and studied which influence surface cracks of cutting tool from prefabricated stress σc, brazing stress σq, removable stress σw at heat preservation and extra stress σf several aspects in this paper. Then the author founded the math-mechanics model of forming the surface cracks and deduced the critical condition generated surface cracks in brazing welded cemented carbide cutting tools and puts forward several kinds of technology, crafts and methods restraining or minishing surface cracks of the cemented carbide cutting tools.
