To improve the development of automatic inspection technique, an effective system that incorporates computer-aided inspection (CAI) and computer-aided analysis (CAA) subsystems into CAD/CAM system for industrial use is urgently needed. In this paper, a new concept is proposed for dimensional inspection and geometry error analysis by introducing the idea of Virtual-CMM. In recent years, because of the improvement in measurement hardware, it is easier to get huge and high precision measuring data than before. But the general solution to handle this large and random data had not been found. To solve this problem, the Intelligent Virtual-CMM system is developed. The developed Virtual-CMM system is a computational analysis software kernel aiming at analyzing the “virtual part”, which is a collection of scanning points of products created by any type of dimensional measuring equipment (DME), such as laser scanner or CMM. In this measuring system, it provides common analysis tools such as alignment, best-fit of standard and free-form geometric features, intersection of geometric entities, form error evaluation and tolerance analysis. It is tedious and slow to inspect a complex part using the manual operations or simple CNC measuring methods. To solve this problem, the CAD directed inspection module included in the Virtual-CMM system is proposed. This module includes the automatic generation of inspection points, the simulation of the inspection process, and the creation of a DMIS CNC inspection program that will automate the CMM inspection. In addition, the inspection result from the DMIS CNC inspection codes can be returned in the DMIS format, and can feed back into the Virtual-Part analysis module to analyze the inspection results by registration and best-fit methods.
