Reverse engineering

Reverse engineering aims at analyzing and understanding the design of an existing product in order to create a copy, make improvements, or solve problems. In the case of mechanical parts, reverse engineering is often necessary due to the absence of plans or CAD models. The use of a 3D scanner and a measuring arm can be highly advantageous in the reverse engineering process.

Reverse engineering a mechanical part involves several steps to understand its design and create an accurate 3D model. Here are the general steps of a reverse engineering process:

data acquisition

The first step is to obtain data from the existing part, which can be done using a 3D scanner on a measuring arm. The goal is to collect all the necessary information about the geometry, dimensions, and features of the part.

data processing

Once the scanning or measurement data has been acquired, it needs to be processed to obtain a usable mesh. This may involve cleaning up raw data, aligning scans or measurements, or merging different parts of the part.

3D modeling

A 3D modeling software is used to create a digital model of the part from the mesh. The reverse engineering CAD software can be a specialized tool like Geomagic Design X, Polyworks Modeler, or a more general-purpose software like Catia, NX, SolidWorks.

Verification and adjustments

Once the 3D model is created, it is important to verify it against the original part. Compare dimensions, shapes, and features to ensure that the model closely matches the existing part. If necessary, make adjustments to improve the accuracy of the model.
