The number of copies is commonly known as the reverse project. It is called shape in Jiangsu and Zhejiang. It is often used for imitation work. It is a reverse process designed in the usual sense. That is, the laser copy machine scan the existing model to obtain the three -dimensional contour data, and cooperate with the professional reverse engineering software for the model to repeat it, and finally generate a CNC program, and perform CNC processing. Today, with the rapid development of computer technology, the three -dimensional geometric modeling technology has been widely used in the manufacturing industry in all aspects of the design, solution review, automation processing and manufacturing, and management and maintenance of product and work mold. The technical data we receive from upstream manufacturers may be a three -dimensional model of various data types, but for various reasons, what we may face is not a model of CAD, but a real physical sample, sometimes, even may even be possible Even a reference drawing does not exist, which brings great obstacles to our subsequent work and advanced manufacturing technologies in the subsequent work. We must use various measurement methods and three -dimensional geometry modeling through various measurement methods and three -dimensional geometry modeling Methods, converting the original physical (product prototype or sludge model) into a three -dimensional digital model on the computer, in the field of CAID and CAD, this is the so -called reverse engineering technology (the English in English is Reverse). Some issues that should be noted in reverse engineering technology work to do a reverse engineering work may be more challenging than doing a positive design, because if you want to make a perfect product, you must first try to understand the design ideas of the original model. On this basis, it may also be repaired or overcome the defects existing in the original model. In a sense, reverse engineering technology is also a redo -design process. Before starting a reverse project, we should carefully consider the following main points of reverse engineering technology: the type of the model: free curved surface, car, motorcycle outer coverage, other stamping parts, toys and other primary analytical curves -plane, cylindrical surface, cylindrical surface The type of parts composed of cone surface and other parts of the parts is directly related to the modules or software selected when we modeling. For free curved parts, the modules with convenient adjustment of curves and curves must be used. There is a random curved surface to fit a curved surface with a free curved surface. The quality required by the model: Class A surface, such as the outer coverage of the car and motorcycles, the B -level surface of the car, such as the interior of the car, the quality of most plastic parts of the plastic parts requires lower curved models. Selected, for example, for the A -class surface, it is required that the software must have a convenient and direct surface adjustment method, the powerful curved surface detection function, and the detection result must be dynamic, that is, the curved surface adjustment is updated. Of course, there are no 100 % things in the project. Taking the A -class surface on the outer surface of the car as an example, the connection error between the two noodles is mainly large: the cut error should be 0, and the curvature error allows within 0.1; For other curved cutting errors, the permission is allowed to be less than 10 points. Reverse engineering technical measurement method: Simple tools of hand -measurement mechanical tri -nald measuring machine measurement measured data laser, digital imaging three -coordinate measurement data, which is a large number of ordered cloud data. It is more convenient to use laser and digital imaging measurement methods. If you only need to measure the main line, it is more appropriate to use a mechanical measurement machine. The quality of the original physical, the accuracy of the measurement data, whether there are noise points, how to consider the benchmark during multiple measurement, and how large is the error. If the quality of the original physical object is high and the accuracy of the measurement data is high, the established curved surface and measurement data should be adjusted to a relatively small value. For example, for a relatively good car mud model, the adjustment error should be small and 1.5-2 after the adjustment. Millimeter. The downstream application field of the establishment model is just for design, or for molds, processing or analysis. For example, if you only do the design, you can consider some technical details, such as the slope of the departure. However, if you want to process and analyze, the model must be complete. If the mold design and processing, some small rounded corners can be omitted, and the tool is automatically brought out by the tool during processing. The reverse engineering technology tools that PTC can provide can be used to process the measurement point data in the product of PTC. Features, suitable for different application areas. ICEM Surf is a constructor of A -level free curved surface. Its main feature is dynamic evaluation of direct constructing curved surface (no need to construct curve) and curved surface quality (dynamic update of curved surface diagnosis results in curved surface adjustments), outside cars, motorcycles outside the car, motorcycle car Free curved surfaces such as covering parts, interior parts are used to construct it. But it is best to have a relatively complete measurement data. Of course, ICEM Surf can also be used to construct the design of the surface. ICEM Surf can also automatically convert the point cloud data into a triangular dough model. You can use it to find any cross -section line, boundary line, and feature line. It can also be used for fast molding or NC processing programming. But this surface is not a traditional curved model. Pro/Designer (CDRS) is a modeling module of industrial design, which is mainly used for conceptual design. Its characteristic is that it can easily adjust the various lines to get the result that the designer wants to get. When used in reverse, it can be used in the case of relatively small measurement data, only the main line and boundary line. This is actually a part of the reverse direction. Pro/Scantools is a reverse curved construction package that is completely integrated in the Pro/ENGINEER physical modeling. The functions in the new version of 2000i have greatly improved. You can accept an orderly point (measurement line), or you can accept point cloud data, which can be used to build non -A -level free curved surfaces. General industrial products such as electrical products, general plastic parts, and car interior parts can be applied to this. The module is successfully resolved. For parts composed of primary analytical planes, the entity and curved integrated scheme of Pro/Engineer can be directly solved. Of course, the measurement data can be directly used as the basis for the shape, but it should be emphasized that the purpose of our reverse product is the function of the product rather than the specific small structure.
Computer copying staff is the number of copies. The existing sample model is copied through three -dimensional scanning Sentu copied companies are generally exported to STL format, which can be used directly in the sculpture and and and again Or import it into the three -dimensional design software to make models generate entity, divide molds, process processing
