Research Abstract	The design guide of joints is considered to improve the thermal characteristics of multi-axis and multi-tasking machine tools. As the results, the following matters are made clear. 1) The thermal contact resistance becomes larger than the one under the uniform contact condition, if the contact condition of the joint interface has deviation. 2) Thermal characteristics of multi-axis and multi-tasking machine tools can be nearly estimated by analyzing the thermal deformation with consideration of the thermal contact resistance of joints. 3) The thermal characteristics of the machine tools can be improved by controlling the thermal contact resistance of the joint interface.
