| Abstract: |
| To meet the requirement of the complex structure product development on digital manufacturing technology, a three-dimensional model based digital process planning method and its three-dimensional application mode are presented in this paper. The connotation, research status and existing problems of three-dimensional digital process planning are addressed. Three key issues to realize 3D digital process planning have been discussed. The 3D digital process planning based on 3D manufacturing process model plays an important role in complex structure product development, which can effectively improve process planning and shorten product development cycle. |
