Surface Roughness/Finish
This category includes systems used to inspect the surface integrity of a workpiece after it has been processed by any surface modification process, including forming, metal cutting, welding, surface treatment, or other surface alteration. In the fabrication process, a surface’s roughness is a measurement of the height of irregularities and asperities on a finished surface after machining. ‘Finish’ is not a measurable quality, but depend on the viewer’s perception and the requirements of the task. Devices used to measure the roughness of a workpiece’s surface are called profilometers; manual comparison can also be made against a sample of a known surface roughness.
Automation and Metrology
To remain competitive, more shops are searching for ways to better utilize their quality workforce and supplement them with automation. But Ken Myers of Mitutoyo America explains that what automating metrology means to one person might not mean the same to another.

This high-intensity, multidirectional lighting camera technology makes easy imaging of challenging part features on machined heads to provide a clear advantage for this automotive supplier.
The flawless surfaces required in mold making demand large cutting volumes during the roughing sequence, but a perfectly finished surface at the end. This analysis from Heidenhain examines how, along with high quality machine tool mechanics and control performance, the optimal milling result necessary to do this depends heavily on the measuring technology.
The Vanta Element from Olympus Scientific Solutions Americas provides the same fast material- and alloy-grade identification as the line’s other models in a rugged, cost-effective package. The 2.9-lb X-ray fluorescence (XRF) analyzer works in temperatures ranging from 14 degrees F to 113 degrees F (-10 degrees C to 45 degrees C).
Mahr Inc.’s Precimar ICM 100 IP can be retrofit to automatically calibrate dial and digital indicators, test indicators, and dial comparators. Six higher-resolution options expand potential applications for MarCator 1086R-HR and 1087R-HR digital indicators.
A MarSurf GD roughness measuring station from Mahr Inc. can do profile and waviness evaluations in addition to surface roughness evaluations on larger parts or a series of smaller parts staged together – all on the same machine.
