| Abstract: | The spatial position errors of 3-axis NC machining center are measured by using the cross grid encoder, and a mathematic model of volumetric position errors is established. An error compensation method based on ANN technology is proposed and an error compensation model with neutral network system is set up- Through an experiment to measure and compensate the spatial position errors, the feasibility of applying this compensation method to NC machine tools is validated. |
