In ancient China, there was a mythological story about a young boy named Ma Liang who learned a painting by himself and got a magic pen。
　　The copy number is a common name for reverse engineering in Guangdong, and it is called modeling in Jiangsu and Zhejiang. It is often used in imitation work. It is the reverse process of design in the ordinary sense。That is, using a laser scanner to scan existing models,Get 3D contour data,Collaboration with professional reverse engineering software for model reconstruction,Finally, the NC program is generated and CNC machining is performed。
　　Reverse engineering is a reproduction of product design technology,The reverse analysis and research of a target product,In order to deduce and derive the product's processing flow、Organizational Structure、Features and technical specifications and other design elements,To produce similar, but not exactly the same products。
　　Today, with the rapid development of computer technology, three-dimensional geometric modeling technology has been widely used in the manufacture of products and tooling design, program review, automated manufacturing and management and maintenance of all aspects. The technical data we receive from upstream vendors may be three-dimensional models of various data types. However, due to various reasons, we may not be faced with CAD models, but may be actual physical samples. Sometimes, it may even be possible. Even a drawing that can be referenced does not exist, which brings a lot of obstacles for us to adopt advanced design means and advanced manufacturing technology in the follow-up work. We must pass various measurement means and three-dimensional geometry to check numbers. The modeling method converts the original physical object (product prototype or sludge model) into a three-dimensional digital model on a computer. In the CAD field, this is the so-called reverse digit modeling reverse engineering technology。
