【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.更多还原
