Aiming at low efficiency, low accuracy and other issues existing in large lathes geometric precision detection, the paper proposes a new method of measuring geometric precision of lathes. The method is based on the principle of GPS positioning, Using a laser tracker on four different positions, the coordinates of the same target points with a continuous trajectory could be acquired. By a large number...
Aiming at the disadvantages of present methods for detecting machine geometrical precision, the multistation and time-sharing measurement method is used to detect the machine precision in the research. Laser tracker measures the same trajectory of the machine at different base stations successively. Then the coordinates of different measuring points in the machine motion process can be calibrated...
In view of the inherent localization of traditional contact CMM, we exploit a miniature five-coordinate laser and CCD compound measuring machine. It is competent to measure such kind of workpieces which are soft, easy-deformed and with complex structure. This machine adopts several key technologies including the latest digital measuring technique, high-precision mechanical structure, laser prober...
