Paper Abstract

We improved the measurement precision of the original measurement system, combining the optic measurement system and the error measurement forecast system. We have done parameter-operation control over the error forecast model of NN by using the Genetic Algorithm of Chiasma, Reciprocation and Aberrance. By doing so, we effectively prevented the local astringency of the forecast model. We have got error measurement information from the more economical discrete standard source according with the signal-sampling theorem of the error forecast system. The standard source and the workpiece measured are two framework systems on the same conditions. We can do real-time forecasting and correcting of the measurement error.
