| Outline of Final Research Achievements |
Conclusions of this study are to enable following two processes; ① Evaluation of basic grinding performance based on statistical conditions of wheel working surface. ② Simulation of three-dimensional roughness of ground surface. The former can be possible by the measurement of three-dimensional profile of grinding wheel on the machine. The conditions of wheel working surface can be grasped as the statistical properties of grain cutting-edge distribution. The latter can be executed based on effective model of depth-of-cut considering supporting stiffness of grains. Three-dimensional roughness on ground surface can be simulated from three-dimensional working surface profile and effective cutting-edge distribution. As the elastic displacement of working surface is estimated about 10 to 20 μm, it is confirmed that the roughness values are almost same between actual ground surface and simulated result.
