Abstract

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.
