With small dimension parts and using the GOM small objects modules, you can count on accuracy of the order of ±0.01 m m. At the other end of the scale, on a rotor for a wind turbine we will get ±0.6 mm.
Here is a summary table of the tolerances to expect.

We have two very accurate digitising systems: an optical system and a mechanical sensing system. If your parts are too fragile or too soft, we can use the GOM ATOS scanner which works on projected fringe patterns. If your part is too delicate or too large to be sent to us, or if it is being used in production, the scanning service can be performed at your location.

We can digitise parts measuring 10 mm using the Small Objects module, but also items several metres long using an optical coordinate measuring machine.

We supply you with a control report including a 3D colour cartography of the differences, PDF format screen grabs and also 3D software for viewing and measuring.  In this way it is possible to create sections and dimensions at a later date or to check precisely the differences at all points on the digitised geometry. The check is carried out on the whole of the part and not elements of it and concerns both its geometry and dimensions. It highlights, for example, defects linked to plastic injection (bubbles, distortion, burrs, etc.) Interpretation of the control report is done instantly and is easily understood, even by non-experts.

Creation of a DFN, direct machining of a copy of your pattern, digital archiving, dimensional control, carrying out a cartography of the difference between the actual part's 3D-file and the theoretical CAD.
