MBD-BASED THREE-DIMENSIONAL PROCESS DESIGNING METHOD AND PLATFORM FOR TYPICAL AUTOMOBILE MACHINED PART

摘要

The present invention falls within the technical field of computer-assisted process design, and an MBD-based three-dimensional process designing method and platform for a typical automobile machined part are disclosed. By taking three-dimensional CAD software as a carrier, an MBD design model as an unique data input, and a process MBD model as a data output, the design flow comprises steps such as establishment of MBD-related standards, creation of an MBD design model, feature classification and creation of a feature library, feature recognition and information extraction, generation of a machining element, procedures for generating a machining element cluster, sequencing of procedures, and creation of a manufacturing feature body and a procedure model. The final application example of the present invention is realized in a three-dimensional CAPP system with NX as a carrier and developed in C++ and NXopen languages. According to the present invention, the process MBD model integrating a process model and a manufacturing feature body can be rapidly generated, visualization of the process design flow can be realized, and the process design efficiency can be improved, thereby laying a foundation for the integration of CAD/CAPP/CAM.
