The thermal deformation of the machine tool column is one of the major problems preventing the achievement of high precision machinings. For the protection of earth environment, the developments of lower power consumption methods decreasing machine tool thermal deformations have been demanded. In general, machine tools have rib structures both to decrease their masses and to realize easy manufacturing, being taken minute attentions of their thermal deformations and mechanical properties. In order to make effective use of the rib structure to improve thermal and mechanical properties under the lower power consumption, the effects of the rib structure on the thermal deformation and static deformation were discussed for the model of a column rib structure by numerical simulations using finite element method. The optimum design values of the model were depended on the objective function. The objective function of thermal deformation resulted in the larger rib height and smaller rib width than that the objective function was static deformation.
