Study on a three-dimensional digital assembly process planning system

Assembly planning is a sophisticated problem. The traditional computer aided process planning systems are two-dimensional, and now there aren' t commercial three-dimensional digital assembly process planning systems. Taking the turbine pump digital assembly process planning system developed for a factory by the author as example, the architecture of the system is presented, an integrated assembly model is erected, and key technologies involved in the system are studied. A method combining geometrical reason with human knowledge is applied to generate the best assembly sequence. Path planning and collision detection algorithm is implemented. The interactive assembly process planning and simulation system is developed under 3D environment.
