An effective method has been proposed to evaluate the thermal deformation of an NC machine tool. This method uses a touch probe and a master block, as well as a mathematical model of thermal deformation derived based on the finite element method. Thermal displacement between the spindle and the table is measured for three directional components in Y-Z plane of the machine along the Z axis movement. Then, by determining the parameters in the mathematical model so that the measured thermal deformation fits the corresponding value of the model, each deformation of the head and the column as well as its change due to relative position is clarified. Experiments have been carried out by rotating the main spindle of a machining center without cutting to verify the effectiveness of the method.
