NMF Software (NMF OS)
All products are provided with our NMF OS software. This intuitive workflow based software allows you to setup and perform a measurement in a matter of minutes, calculate and analyze the results and export your data for iterative machining. DUI also offers optional software modules which enable advanced measurement input and analysis of freeform surfaces. For more details, please contact DUI.
NMF Benefits
- Setup for any type of surface in minutes
- No setup costs
- Easy to use, results in minutes
- Measure during entire manufacturing process (from ground to finished)
- High-density error maps and linescans, incl. absolute radius measurement
- Single nanometer rms level form error repeatability, even for large wild freeforms
- Traceable calibration to NMI certified artefacts
Custom Metrology Systems
The NMF platform is modular and scaleable so it can be adjusted to your specific metrology needs regarding for instance diameter, height, product interface etc. Contact DUI to discuss your application requirements.
