Abstract: Aiming at the application situation of Model-Based Definition (MBD) technology in process planning,the definition of model-based process was proposed.By taking the process model as basic unit,process MBD information was organized with the machining features,and the model-based part process administration architecture was established.Taking the process model as carrier,a part process information model based on MBD was built.A three-dimensional process annotation sign was put forward,and its composition was also analyzed.A three-dimensional process annotation module was developed,and a part annotation was taken to illustrate the validity of the method.

Key words: model-based process, process model, three-dimensional annotation, computer aided process design
