Calibration methods for 3D mechanisms are necessary to use the mechanisms as coordinate measuring machines. The calibration method of coordinate measuring machine using artifacts, artifact calibration method, is proposed in taking account of traceability of the mechanism. There are kinematic parmeters and form-deviation parameters in geometric parameters for describing the forward kinematic of the mechanism. In this article, the kinematic parameters which describe the forward kinematics when all elements of the mechanism have no form deviation, are taken up to be calibrated using artifact calibration method. Firstly, the calculation system which takes out the values of kinematic parameters using least squares method is formulated. Secondly, the estimation value of uncertainty of measuring machine is calculated using error propagation method. The artifact calibration method is applicable to various types of 3D mechanisms.
