1. Curve Process: Decide on the type of curve to be created. The curve can be designed to be the same as a fragment of a point, or to make the curve smoother; create a surface from an existing point; check/modify the curve, check the accuracy, smoothness and continuity correlation between the curve and the point or other curves.
2. Error analysis: you can consider the integrated trajectory error caused by the measured object to the mechanism, the measurement error that exists in the data values on which the reverse engineering design is based, the machining error that exists in the measured object in the design, and the fitting error that exists in the curve-fitting in the design, etc.
2. 4. Reverse engineering starts with a model or a physical part, which then determines the downstream engineering.
3, point processing process: mainly includes point cloud chunking, collocation of multi-view point cloud, point cloud filtering and data streamlining. This article is completed by Hunan Huashu Hi-Tech rapid modeling editorial.
Extended information
Reverse engineering role:
I, shorten the product design, development cycle, accelerate the speed of product replacement;
II, reduce the cost and risk of enterprise development of new products;
Three, accelerate the product modeling and serialization of the design;
four, suitable for single-piece, small batch parts manufacturing, especially the manufacture of molds, which can be divided into direct mold making and indirect mold making method.
1, direct molding method: RP technology based on rapid direct molding method is the mold CAD results from the RP system directly manufacturing molding. The method does not need to use RP systems to produce samples, but also does not rely on the traditional mold manufacturing process, metal mold manufacturing is particularly fast, is a very promising development of the mold method;
2, indirect molding method: indirect molding method is the use of RP technology to create a prototype of the product parts, prototype as a master mold, mold core or mold tool (grinding mold), and then with the combination of traditional molding process, the manufacture of the required mold. out the required mold.
