Copycad In Reverse Engineering
As a means of advanced product design, reverse engineering in China are now more and more importance in enterprises, reverse technology, attention of more and more widely. Reverse Engineering (Reverse Engineering) project concept: Through the existing product model three-dimensional digital scanning, to obtain the product model of the surface contour of the point cloud data, the point cloud data processed by specialized software and ultimately the formation of three-dimensional mathematical model for product re-design and CNC machining and structural analysis. It is different from our usual two-dimensional sketches by the three-dimensional model of design to design and then to processing or rapid prototyping of design ideas, so it is not based on solid mathematical model of design.
Reverse engineering is widely used in aerospace, automotive, mechanical, electronic and mold, toys, medicine, footwear and other industries, its application mainly in the following areas:
1. The design of new parts, mainly used for imitation products, modifications or design.
2. Has been part of the copy, reproduction of the original product's design intent, data management and archiving.
3. Parts directly from existing products to quickly generate STL models for rapid prototyping (RPM) or mold design.
4. Digital model of the testing, deformation analysis, finite element analysis, as well as comparison with the original design model.
5. To restore damaged or worn parts and repair.
However, as the kinds of emerging technologies, many enterprises on the reverse engineering does not understand that as long as three-dimensional measurement or scanning equipment, a common
CAD Software can reverse the work. In fact, this is not enough, in the reverse engineering of the application process there are many other common reverse software and CAD software can not be achieved in the difficult, reverse reverse must have a professional software and process knowledge to complete such a complex good work.
Professional reverse software relative to the general advantage of the software:
1. On the measured data for optimization and editing capabilities
: Because there are many measurement devices can provide scanning, so reverse the software required to read the vast majority of devices have generated a different point cloud data format capabilities. At the same time as the number of point cloud is very large, often several hundred thousand to tens of millions, or billions of points need to be addressed, which requires the software to reverse such a huge amount of point cloud data with efficient computing, editing capabilities. With the premise of ensuring the quality of surface optimization to reduce the number of point clouds, ruled out the functions of dead pixels. As the model also tested different geometry and different equipment, different measurement purposes to determine the measurement process and the different measurement methods. This requires that reverse software can have these different classification ability.
2. To Triangle model optimization and editing capabilities:
As the measuring device accuracy is not high, the low quality of measurement data, measurement models such as defective or damaged for various reasons, tend to cause the resulting STL model have many holes and gaps, which need to reverse the software with powerful editing STL model and optimization of processing power, can be designed within the tolerance allowed repair, smoothing triangulated surfaces. It should also have the Boolean operation on STL model and design model, consistent with the design of the STL model generated, thus unnecessary to convert the surface model for other CAM mold design or processing software can read the question, because it will greatly increased workload and reduced efficiency.
3. Difficult to use surface fairing, skills and strong:
As the reverse of the product are often more complex products, surface structure is complex, often need to generate to B-Spline or NURBS surface based on surface, and the need for multiple surface tailoring, stitching, rounding, smoothing and other editing Therefore, smoothing the surface and the ability to generate strict, and most software can only reverse into a curve point cloud processing, and then switch to other CAD software using curves generated surface dimensions of the way, this way of generating a single, heavy workload encounter complex body of work is extremely complicated products, but also easy to cause large deformation, which makes the formation of surface depends largely on the experience of engineers.
4. System integration problems with other software:
Since many CAD / CAM software does not reverse the function, while the common reverse the software does not have strong surface editing capabilities and assembly, the drawing function, it is necessary to reverse combination of software and cad software to complete the reverse, and this is on the need to reverse the process of frequent data format will be different in different software to convert each other, this will certainly result in the loss characteristics of the data file and may even damage the data file, and also makes the work more tedious work and reduced efficiency .
Address the problem, DELCAM professional company provides a complete reverse engineering solution.
DELCAM is the world's leading CAD / CAM software suppliers, five major software:
PowerSHAPE, PowerMILL, CopyCAD, PowerINSPECT, ArtCAM Range from three-dimensional product design, CNC machining, quality control and reverse the process of design integrity. For reverse engineering, Delcam software solution see the following figure:
First, by measuring the equipment or scanning equipment to the existing three-dimensional model of the scanned point cloud data into Copycad in reading. In Copycad the one hand can generate triangular facets of the STL model, the output STL model to
Rapid Prototyping Equipment For rapid prototyping, or output to the PowerSHAPE for mold design, you can output to PowerMILL for machining. On the other hand can be generated in Copycad surface, three-dimensional output to PowerSHAPE design, assemble, mold design and a two-dimensional drawings. While Copycad can also be a prototype three-dimensional CAD model of a comparative analysis of output error analysis. Comparison of design defects in the production process and deformation.
Reverse the world's leading software, CopyCAD reverse the course of their work areas with the following features:
1. Dealing with point cloud data:
CopyCAD input and output with a friendly interface, supports multiple formats of the point cloud data read. In addition to generic ASCII, IGES and the NC and other standard formats, but also for different scanning equipment specific data format.
The input point cloud data, CopyCAD for different measuring apparatus and provide
