Research on Three Dimensional Computer Assistance Assembly Process Design System

摘要

The computer aided process planning will certainly play a significant role in the success of enterprise informationization. 3-dimensional design will promote Tri-dimensional process planning. This article analysis nowadays situation and problems of assembly process planning, gives a 3-dimensional computer aided process planning system (3D-VAPP), and researches on the product information extraction, assembly sequence and path planning in visual interactive assembly process design, dynamic emulation of assembly and process verification, assembly animation outputs and automatic exploding view generation, interactive craft filling and craft knowledge management, etc. It also gives a multi-layer collision detect and multi-perspective automatic camera switching algorithm. Experiments were done to validate the feasibility of such technology and algorithm, which established the foundation of tri-dimensional computer aided process planning.
