Abstract
Reverse engineering is currently used for product development and imitation of an advanced means of processing, is set measurement technology, CAD technology, laser technology, materials technology and computer-controlled technology, which integrates high-tech, it addresses the existing part (or sample MODEL), using 3 D digital measuring instruments quickly and accurately measured the outline of a large number coordinates, and coordinates of these points denoising, match to build, the revised import to CAD / CAM system, generating the NC tool processing path, or enter CNC to generate the necessary die, or generate a certain format of the files into a rapid prototyping machine will be created by the sample model. Three-dimensional optical measuring machine is one such device, which can be three-dimensional physical space of the detected objects copied to the 3D data space and return them, we call it the establishment of three-dimensional model. This ability to 3-D scanner has a very great prospect. Since reverse engineering is a wide range of applications and practical value, the world's major industrial countries have invested heavily in research and development of the technology and application, they all stand in the 21st century global competition in world manufacturing strategy to deal with this highly A technology. Currently the technology has been widely used in the rapid development of machinery parts, automobile and aircraft coverage of the rapid detection and anti-seeking, rapid tooling, medical and rehabilitation engineering, home appliances, industrial design, craft making and children's toys, and other fields and achieved A huge economic benefits. The optical design is complete three-dimensional measuring machines and mechanical control system design, the paper's three-dimensional structure of optical measurement system is a grating structure of binocular vision measuring optical scanning technology. Since the scan, therefore, have great speed on the edge, you can achieve very good surface tested free of the fast, high-precision 3D measurement. By measuring machine parts parts of the design, the final completion of three-dimensional optical measuring machine design.
