Al2O3-TiC ceramic tools are used for finish machining of cast iron. But these tools break easily in wet cutting. In order to overcome this problem, the cutting performance of hyperfunctional Al2O3-TiC ceramic tools with symmetrically graded structures of Al2O3/TiC/Ni/TiCAl2O3 were studied. Two hyperfunctional ceramic tools with different types of layering were fabricated by SHS/HIP processes. Al2O3-TiC ceramic tools with symmetrically graded structure of concentric layers showed good breakage resistance in wet cutting as compared with monolithic Al2O3-TiC ceramic tools fabricated using the same process. Numerical calculation using the finite element method (FEM) showed that the Al2O3-TiC ceramic tools with the symmetrically graded structure of concentric layers had strong residual compressive stress at the edge of the tool in the direction parallel to the edge. It seemed that this compressive stress was effective in preventing breakage.
