A calibration method for three dimensional coordinate measurement machine(3DCMM) in terms of sequential-two-points method is proposed. Two sensors are attached to the probe of a machine and an Al plate machined by milling machine is placed on the table as the objective, then the probe is moved step wisely with interval of the distance between two sensors by NC indication of the machine along x axis, which makes it possible to identify the straightness error movement of the probe. By repeating the evaluation of the movement stepwisely again along y axis flatness error movement of the probe can be obtained, which is possible to calibrate the positioning accuracy of the probe in the plane. Statistical evaluation of the measuement is conducted, which leads to that reliability of the measurement is raised.
