Cmm-based Profile Measuring Method for Unknown Screw Compressor Rotor

摘要：

　　The measurement for unknown screw compressor rotor profile is a nodus in CMM measurement because of the complexity of 3D helical surface,whose surface normal vector is uncertainty.For this reason,conventional 2D measure-ment methods exist theoretical error.This paper provides a quadratic measuring method.The second-measurement is an accurate 3D measurement with the normal vectors of measured points,which can be figured out based on the 3D modeling of the first-measurement.In this paper,some key technologies such as screw pitch solution,3D path planning on CMM and normalization of measured rotor profile data are resolved legitimately.
