Abstract

Surface of a precision rotor, a typical helical surface with complicated 3-D shape, is hard to measure with CMM accurately due to the difficulties of spiral scan and probe compensation. Aiming at this problem, an apparatus, avoiding probe compensation directly by means of non-contact measuring, is designed and developed based on laser triangulation, and the corresponding method for measuring parameter lead and transverse section profile is proposed based on geometric feature model expressing the surface of precision rotor. After apparatus is calibrated with a standard plane and ring gauge, experiments are carried out to scan spiral line and measure transverse section profile respectively, and results of lead error detection and profile error evaluation satisfactorily match the theoretical values provided by manufacturer.
