Frontiers of Mechanical Engineering 2016, Volume 11, Issue 4, Pages 423-432 doi: 10.1007/s11465-016-0382-1

Abstract:

An assembly design system is an important part of computer-aided design systems, which are importantThe traditional assembly design system does not record the connection information of production on theengineering layer; consequently, the upstream design idea cannot be fully used in the downstream designAn assembly design model based on the relationship of engineering connection is presented.The relationship between the CAP system and the commercial assembly design system is also established
