Research And Practice On Object-Oriented Computer-aided Plank Furniture Design System

In the process-oriented computer-aided plank furniture design system, there is only the geometrical graph to express furniture product, but there is no necessary information such as material, process, and assembly etc. For this reason, when furniture enterprise implements information integration, it's difficulty that CAD system integrate with other system such as CAPP, CAM, ERP etc.After deeply research on design principle and design method of plank furniture, a computer-aided plank furniture design system is developed by using object-oriented method. This system simulates the real design activity, can aid designer to finish plank furniture design, and integrates effectively other system such as CAPP, CAM, ERP etc. The main work of this dissertation includes :1 Analyzes deeply various object-oriented modeling methods. According to the requirement and characteristic of plank furniture design, this dissertation use integrative object-oriented modeling method to develop the item.2 Research on part modeling and components modeling of plank furniture. According to their characteristic, this dissertation finishes their object information model. This dissertation researches reused components database too, brings forward the method to restore and pick-up components.3 Research the key technology of plank furniture fitting design including identifying the connection types, fitting database, automatic locating holes, and finish fitting connection object model to resolve the questions.4 According to above research, a applied computer-aided plank furniture design software have been developed. It's used in GuangMing Co. It's proved that it fill the requirement of furniture enterprises.
