The measure unit adopts RENISHAW LP2DD probe. HEIDENHAIN linear and round encoders of the machine can as position feedback element. The measure system uses interruptive function of CNC system. When the probe is touched, CNC system will receive a interruptive signal and memory current coordinate position of CNC axes automatically, then after software deals with these information, the real measure data will be got. Compared with theory data, measure error data will be gained.
