Test and Signal Procession of Circular Locus Motion Errors

This paper offers the systematical and deepgoing study on the modeling, testing and recognizing of the errors of a common motion form, the circular locus motion, of precision instruments and machines. The time domain correlation coefficient characteristic method based on Bayes classifiers and the frequency domain spectrum characteristic method based on distance survey classifiers are proposed and the recognition results on practical circular locus motion errors are satisfactory.The result provides a new and important means for the accuracy adjustment and error control of the circular locus motions of precision instruments and machines.
