Abstract
A novel method for measurement and evaluation of cylindricity error is presented. The surface data of a workpiece can be measured from different views using digital fringe projection profilometry, and these data can be connected accurately using multi-aperture overlap-scanning connection technique. Thus all surface data of a workpiece can be obtained. The proposed method offers such advantages as non-contact, high efficiency and whole-field information. It can also be used to effectively overcome the axial undersampled problem with reference to the existing cylindricity measurement method. On the basis of new GPS, verification operators used for cylindricity error evaluation are constructed. The accuracy and reliability of cylindricity error evaluation can be ensured with the standard and optimal operation process. The validity and performances of cylindricity error measurement have been investigated through experiments.
