A STEP-NC Compatible on-Machine Measurement System with Automated Correlation of Inspection Data

Abstract:

On-machine measurement (OMM) is an important part of closed-loop manufacturing (CLM) system. How to achieve real-time measurement operation and measurement result integration claimed by CLM is a major issue that concerns software and hardware vendors. This paper proposed a STEP-NC compatible on-machine measurement system that was compatible with interoperable data model. In the beginning, information model of the system was proposed referring to current data model standards supporting closed-loop manufacturing. After that, a hierarchical process planning approach was present to plan the OMM process. Object-oriented macro programs were utilized to post process the planned inspection information and ensure the correct measuring result correlation. Besides, inspection items and measurement points were uniformly and uniquely identified to ensure the accurate and reliable associations of measurement results with the design model. At last, a STEP-NC compatible on-machine measurement prototype system was developed based on CATIA, and the validity and practicality of the proposed on-machine measurement system was demonstrated with an aeronautic test part.
