What is Reverse Engineering?
Reverse Engineering has different meanings according to professional groups. for the manufacturing industry, the process of creating CAD data using digitization systems of a manufactured product. In other words, the discovery of engineering secrets.
How to do Reverse Engineering?
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.
