Construction of MBD Model-Driven Quality Control Data Chain for Parts Machining Process

Abstract

Aiming at the problems of inconsistent data sources and much manual intervention in the process of quality inspection planning, data acquisition and analysis of traditional parts machining, an MBD model-driven quality control data chain model for parts machining process is constructed. Firstly, through the analysis of the MBD model and the quality characteristics-oriented primary inspection planning, the automatic generation of the inspection task XML file for the inspection process is presented. Secondly, the automatic generation method of the MBD model-driven CNC program for the on-machine inspection of the CNC machine tool and the CMM inspection DMIS program is given. Then the automatic acquisition method of the on-machine measurement results of the CNC machine tool based on OPC UA and the CMM inspection results based on the secondary development of PC-DMIS are proposed, which realizes the automatic acquisition of quality data for process-oriented tasks, XML format packaging, and then realize the quality analysis and monitoring of the processing based on quality data. Finally, the MBD model-driven inspection planning and quality data acquisition system (MD-IPQDA) is developed, which significantly improves the accuracy and transmission efficiency of quality data verified by application.
