The working procedure model (WPM), which is composed by a set of models, is used to describe a process of a part made from roughcast to product. And the WPM plays a key role while part being produced. The process information comprises process drawing and process steps and shows a sequencing and asymptotic course that a part is made. The 3D model canpsilat(More)
This paper proposed to get 3D process model and final part through by process language understanding and graphics understanding. Based on the characteristics and structure of the machining process language, machining process language could be represented by “four elements”. Then constructed the knowledge base based on ontology. Through(More)
