Summary
A microcomputer-based forecasting technique for compensating leadscrew drive kinematic errors by the DDS (Dynamic Data Systems) approach is proposed in this paper. The kinematic error of a particular leadscrew drive system was described by an ARMA(16,15) model. In order to facilitate on-line compensation, an AR(9) model was fit instead of the ARMA model. Both models revealed the same dominate error components and have similar spectral plots.
Experiments were conducted on a Giddings & Lewis Model 10V Numericenter. The results show that the cumulative pitch error can be reduced some 80 to 90% through compensation at lower feedrates of the table and about 50% at the higher feedrates using the forecasting technique.
