Abstract:A mathematical model has been established for the error associated with the degree of freedom for each motion axis, with a correction applied based on the 12-line method in three-dimensional space. A multi-beam laser interferometer is proposed, which comprises four lasers, where different laser combinations can be used to measure different parameters, ultimately achieving simultaneous measurement of errors for the six degrees of freedom. This has informed the development of a spatial error measurement and accu… Show more
