Quality control surface roughness
Automated roughness measurement
The surface roughness of purchased parts from various manufacturers is to be automatically checked and documented.
Project partner: Siemens Energy
Requirements
- Verification of the required surface roughness of purchased parts from different suppliers
- Determination of the value Rz according to ISO 4288, e.g. Rz < 100µm
- Additional determination of the surface roughness Sa (average height/roughness) and Sz (maximum height/roughness)
- Images of the scanned depth profiles from different views
- Large number of measurements to cover all product variants
Solution
- Measurements with Keyence 3D profilometer
- Automated calculation of the values Rz, Sa and Sz
- Accurate documentation of the measurements and presentation of the results in a report
