| Research Abstract |
The purpose of this study is to improve the machining accuracy of a workpiece in cylindrical and internal grinding by reducing the effect of thermal deformation of the ground workpiece in the grinding process. To understand the thermal deformation of the workpiece during grinding process, an advanced analysis method of temperature distribution and thermal deformation of a workpiece are developed. In cylindrical grinding, the temperature distribution and thermal deformation can be calculated with a developed simulation analysis system. A new grinding system that can consider the thermal deformation was also developed in this study, With this grinding system, the cylindrical grinding was performed within a tolerance of only 0.1 micro meters.
