| Research Abstract |
The thermal deformation of machine tool has recently become the most important problem to materialize the manufacturing system for the product with higher accuracy and performance. In order to solve such problems, a large number of investigations so far has been dealt with reducing the thermal deformation of machine tool mainly caused by the internal heat sources such as a bearing. However, there is no effective model to express the dynamic and thermal behavior in actual operating condition.
In this research, therefore, to establish the dynamic simulation model of thermal characteristics in machine tool spindle systems with the rolling bearing, the thermal closed-loop concept on the thermal behavior of machine tool spindles has been proposed. Validity of the proposed model has also been verified through experimental investigations under various rotational conditions.
In addition, thermal deformation controlled ultra-precision machine tool structure based on the new design concept has been developed and evaluated its characteristic features and performance.
