| Outline of Final Research Achievements |
The purpose of this study is to develop the intelligent grinding system that can control the grinding machine by predicting the stock removal of the workpiece without using a sizing gauge. In this system, thermal deformation and residual stock removal is simulated during grinding process. As a result of this study, the size error of the ground workpiece was reduced less than 0.5 micro meters even though 2 or 3 micrometers thermal deformation occurred. The residual stock removal due to the elastic deformation of the workpiece system was predicted with 1 micro meter accuracy. Furthermore, the new grinding methods were developed to improve the shape accuracy for traverse grinding of the slender workpiece and internal grinding by a slender grinding wheel.
