The existing problems of temperature measurement for CNC machine tool are pointed out through analyzing research results of temperature measurement methods, temperature measurement points optimum and temperature variables selection technology. The devices and properties of contact and non-contact temperature measurement are compared and evaluated. The error measurement devices and their technology development of CNC machine tool are described. The measurement methods and results of temperature and error are analyzed by testing on a concrete CNC machine tool. It is concluded that some objective rules exist in various machine tools. The locations of sensitive points for temperature and errors as well as its number can be defined.
