In this paper,aiming at the problems that the existing mechanical disappearing stopper-type length-measuring machine has large mechanical error and the temperature deviation of grouped double-scale base material leads to the length deviation,the high-frequency response servo control and laser length measurement technology are applied to realize the au-tomatic ranging and automatic calibration of the length-measuring machine,and the position of the length-measuring stopper is automatically or manually fine-tuned,thus eliminating the mechanical error of the length-measuring machine,compensa-ting the temperature deviation of grouped double-scale base material,improving the length-measuring accuracy of the ma-chine and reducing the labor intensity.
