A Method of Knowledge Based Measurement Points Distribution in Three-Dimensional Inspection Planning

Aiming at promoting the efficiency of inspection planning and improving the integration between digital measurement equipment such as CMM (Coordinate Measurement Machine) and CAD system, a method of measurement-points distribution based on knowledge in three- dimensional inspection planning was discussed in this paper. The algorithm of measurement-points arrangement directly based on three-dimensional CAD models was put forward. Furthermore, a measurement-points distribution tool was developed and integrated with the three-dimensional inspection planning system on Pro/E CAD platform. A case study was also given to validate the effectiveness of the method.
