Improving the machining precision of a machining center calls for minimization of displacements in the machine geometry, but a variety of thermal factors lead to such displacements in a machining center. A study was made of the feasibility of estimating current displacement from the temperature of the parts involved in the displacement. If the current displacement can be estimated, the machining center geometry can be corrected to compensate for the displacement,thereby improving the machining precision. Another object of the study was to find an optimum set of points at which to measure temperature in the machining center, and to determine the feasibility of reducing costs by using a small set of measurement points. The results of the study indicated that displacement could be estimated by use of the T-method.
