  • METHOD FOR IN-SITU NON-CONTACT DETECTION OF SYMMETRY ERROR OF KEYWAY LOCATED ON SHAFT-TYPE WORKPIECE
    Publication number: 20240003681
    Abstract: A method for in-situ non-contact detection of a symmetry error of a keyway located on the shaft-type workpiece includes the following steps: establishing a detection system and a system calculation coordinate system; controlling rotation of a shaft-type workpiece, continuously acquiring data of a detection part by means of a laser displacement sensor, and calculating and analyzing the acquired data to obtain a symmetry error of a detection section; and moving the laser displacement sensor in an axis direction, and calculating symmetry errors of a plurality of sections of the keyway, to obtain a symmetry error of the keyway located on the shaft-type workpiece.
