The bionic tribological studies show that highperformance microtexture can achieve good antifriction properties. A twodimensional finite element analysis was conducted by the software ABAQUS in accordance with the simulated experiment of the bone cutting procedure by microtexture cutters. Morphology changes of the microtexture on cutters rake face was experimented. Besides, temperature changes around the thrid deformation area were compared and analyzed. The simulated experiment indicates that morphology and geometric parameter differences of the microtexture cutter can cause different temperature changes in the third deformation area; cutting temperature is proportional to microtextures spacing and depth, but is inversely proportional to width, which most influences the temperature.
