Recently, as an electronic and an optical part with high precision are required, high precision machining is done very much. At that time, a 3-dimensional coordinate measuring machine (CMM) are used for measuring. However, as the structures of the CMM and the measured part are influenced by ambient temperature fluctuation, the thermal deformation of those structurs reduce measurement accuracy. Therefore, in this report, a few insensible structure technologies for reducing thermal deformation caused by ambient temperature fluctuation were devised and evaluated. Those technologies consist of local cooling for the measured part, structure of thermal insulation using styrol foam with high density and structure of high thermal inatia using the table with water. It is concluded from the results that the proposed technologies were very effective in order to reduce thermal deformation of the CMM.
