<jats:p>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.</jats:p>
