Introduction to reading design

As a brand-new product development concept, replication design (also known as reverse engineering) combines high and new technologies such as three-dimensional measurement, computer-aided design and rapid prototyping. Using laser copier as light source, industrial samples, machine heads and models are scanned at high speed and accurately, and their three-dimensional contour data are obtained. Combined with special reverse engineering software (such as proe and ug), 3D design is reconstructed to generate entities.

Replication is usually called replication design, reverse engineering or reverse design. As the name implies, copying is to copy the 3D data of the template according to the template, so as to realize reverse design. At present, the design of copying is to scan the existing model (template) with a laser copying machine to obtain three-dimensional cloud point data, and cooperate with professional reverse engineering software to reconstruct the model (generally designed by PROE); In China, imitation and reverse design of shanzhai products, especially shanzhai mobile phones, digital products, shoe models and other products are the most common.

In fact, replication is a common name of reverse engineering in Guangdong, and it is called modeling in Jiangsu and Zhejiang. It has become an industry and is often used to imitate works. This is the reverse process of design in the ordinary sense. That is, the existing model is scanned by laser reader to obtain three-dimensional contour data, and the model is reconstructed by professional reverse engineering software, and finally the NC program is generated for NC machining.

With the rapid development of computer technology, three-dimensional geometric modeling technology has been widely used in the design, scheme evaluation, automatic manufacturing and management and maintenance of products and molds in manufacturing industry. The technical data we receive from upstream manufacturers may be three-dimensional models of various data types. However, for various reasons, we may not be facing a CAD model, but a real physical sample. Sometimes there is not even a reference drawing, which brings great obstacles for us to adopt advanced design means and advanced manufacturing technology in the follow-up work. Various measuring methods and three-dimensional geometric modeling methods must be adopted. Transforming an original object (product prototype or sludge model) into a three-dimensional digital model on a computer is the so-called reverse engineering technology in the fields of CAID and CAD.
