How to do?
Optical and laser scanner systems are generally used for backward engineering. First of all, poligon data of the part is obtained by scanning system. Sections are taken using software on the resulting data. Sketches are created on the sections taken. These sketches are finalized by creating solids or surfaces. It can be done by following several different paths;
- Parametric modeling can be done with sketch-based modeling. Since solids and surfaces can be obtained through drafts, the changes made through the sketches are reflected in the entire design.
- With a fast surface, data can be easily generated by modeling. Editing is done on the scan data. (Closing gaps, clearing deformations, editing poligon numbers, softening or sharpening poligon transitions) Then the program automatically creates a surface on the poligon data.
According to part geometry, precision, cost or application, the appropriate method is preferred.
The difference between these two processes is that one is controlled data and the other is data that emerges according to the software’s own algorithm.
Applications of Reverse Engineering
- If the original manufacturer of a product no longer produces the product, the product may need to be removed from 2D / 3D documents,
- Used to continue over when the original design is considered insufficient,
- When original design data is lost or not available,
- To fully reveal the good and bad properties of competing products,
- Creating data for mechanical analysis on competitor products in new product development,
- To explore new ways to improve product performance and features,
- Deformation and displacement analyses of worn parts,
- Used for archiving work.
