The technology of three-dimensional inspection planning for parts is studied. An inspection planning and quality assessment framework based on multi-geometric characteristics is proposed. Then it is introduced through measurement requirements expression based on MBD, inspection planning, measurement execution and data preprocessing, and quality assessment. Finally, the prototype system was developed in the CATIA secondary development platform and the preliminary verification was carried out. The research provides technical support and methodological guidance for engineering and comprehensive evaluation of model-based measurement planning technology.
