Reverse Engineering In Industrial Design In Applied Research

Reverse Engineering (RE) refers to the process of creating engineering design data from existing parts. Some product' s figure is very complicated and is hard to build CAD model directly. To resolve this question, Designers and engineers use some material like clay or wooden mock-ups to make a model of the product, scan it by 3D measuring machine, get the data of the figure, then build it' s CAD model on the basis of the scan data. And sometimes we need to clone and re-create an existing product. The Reverse Engineering technology enables us to create the CAD model of the new product quickly by capturing the surface of a model using laser digitizers or coordinate measuring machines.Reverse Engineering, as a method of design, has been used in many fields. It' s proved that the period of the design can be shorten remarkably. So, in recent years, Reverse Engineering is getting accepted by more and more enterprises.As the main tool to enhance the value of the product, Industry Design is becoming more and more important in the market compete, consumer make the choice not only by the function, but also by the appearance of the product. As product varieties increase and life cycles shorten, the need to reduce development time becomes more critical to maintain competitiveness in the market. Though the CAID (Computer Aided Industry Design) has been widely used, that's not enough. Designers need more powerful tool to make their concept come true and they need to re-create new product on the basis ofinold product.in this thesis, the theory and application of Reverse Engineering in the Industry Design fields are researched in details, which are compared with that of forward design. Some key technologies in the reverse engineering, such as data measuring, data disposal, data output and freeform surface reconstruction are discussed and some actual application examples are showed in the thesis. How to use Reverse Engineering in Industry Design as a creative tool is studied.If Reverse Engineering is integrated in Industry Design as a tool to ameliorate the appearance of old product, the period of the development would be shorten, the cost would be reduced, the level of Industry Design in Yunnan would be improved.
