The slider's three dimensional displacements due to contact deformation at sliding joints are analyzed. The sliding joints are represented by non-linear spring elements which are distributed evenly on the sliding face, and the kinematic model of the slider, including the sliding contacts, is introduced. By using this model, the slider's three-dimensional displacements caused by external forces can be analyzed. It is shown that the analysis can well explain the experimental results which were made through the model of an existing machining center's table. Secondly, the analyzed slider's displacements are converted to the machining error components, and the effect of contact deformation is evaluated. the component which most significantly affects the machining accuracy is regarded, and the corresponding slideway is redesigned to increase its contact stiffness. By repeating this process, the optimal slideway specification can be determined.
