AI Technical Summary
Existing CNC systems in single-segment operation mode have problems such as inability to compensate for creep residual errors related to stop time, failure of compensation after manual intervention, deviation of servo state at single-segment start-up, activation effect of motion direction related errors, and inability to meet the calibration requirements of mass production in factories.
A creep residual error prediction model with a stop time weighting factor is constructed. Combined with non-sensory manual intervention detection, zero displacement servo preloading, and direction-sensitive error activation matrix, dynamic accuracy compensation is achieved through a fully automated calibration process.
It has achieved a significant improvement in single-segment machining accuracy, with a compensation effect of 100%, eliminating start-up step errors and tool marks, and meeting the mass production needs of the factory.
