Error Diagnosis and Compensation Using Kinematic Models and Position Error Data

Abstract A method is described in this paper for obtaining values of coefficients in a kinematic model can be developed Next, the kinematic modal is fitted to position data. Then, coefficients of the model are analyzed so that a diagnosis of the source of errors in the mechanism can be made The results can be used for mechanical or software error correction of machine tools, robots, linkages in sensing mechanisms, etc.
