Latest Patents

One of Guodong Sa's latest patents is titled "Method for predicting thermal error of spindle of computer numerical control machine tool based on twin feature transferring of virtual-real prototype." This innovative method involves building a spindle physical prototype experiment table and screening temperature-sensitive points outside the physical prototype spindle. By establishing an autoregressive distributed lag model, he determines a temperature synchronization lag point on the spindle, allowing for accurate thermal error prediction. This method enhances prediction accuracy, especially when sensor placement on the spindle is challenging.

Another notable patent is the "Evolutionary compensation method for spindle rotation error of computer numerical control grinding machine based on timing in-situ measurement." This method involves determining feature points at the edge of a spindle's central hole and using a measuring device to acquire a trajectory image of these points. By fusing the features of the spindle rotation error with the measured values, a compensation model is established to optimize the spindle rotation error continuously.
