| Abstract: | A measuring method of five-freedom kinematic errors of a moving table along one axis is introduced which employs two laser beams as a plane datum. A mathematical model based on the basic principles of rigid body kinematics is also given. All error computation formulas obtained are simple in form and easy to handle. This method is suitable for real-time, in-situ kinematic accuracy analysis and compensation. |
