【Abstract】 Functionally gradient ceramic cutting tools (FGCCT) are new kind of ceramic cutting tools The cutting properties of the FGCCT can be effectively improved by rational design for the gradient In this paper, the cutting experimental results show that the higher thermal conductive coefficient and the residual compressive stresses in the surface layer are the keys to improving the cutting properties更多还原
