The thermal deformation of a machine tool is caused by the inner heat sources such as bearings, motors and so on, and the outer heat sources, such as the room temperature variation and so on. When the heat generation is pulse-wise or step-wise occurred in an inner heat source of the machine tool and the surrounding temperature of the machine tool varies pulse-wise or step-wise, the thermal deformation can be experimentally obtained or analytically calculated by a computer, so the basic characteristics of the thermal deformation can be obtained experimentally and analytically. Therefore, it is expected that the thermal deformation can be estimated using the basic characteristics when the heat is irregularly generated at the inner sources and the surrounding temperature of the machine tool varies irregularly. In this study, the method for estimating the thermal deformation using the basic characteristics is investigated. As the results, the basic characteristics of the thermal deformation can be obtained by the experiments and the relative thermal deformation can be estimated using the basic characteristics.
