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.

Abrasives Are Not All Created Equal

Quality Manager Tim Urano says Austin-based Wolfram Manufacturing

Many shops hesitate to incorporate abrasive finishing tools in CNC machines for fear of clogging coolant lines and damaging slides and bearings. However, finishing tools generate very little grit.

Prerequisites for High Surface Quality

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.
