Bearing roughness specification
One thing to keep in mind is that Rsk is VERY unstable when trying to measure it on real surfaces. A single pit or pore can drastically change the result. A better approach might be to look at average valley depth (Rv ISO, Rvm ASME) as compared to average peak height (Rp ISO, Rpm ASME)...- mcmalburg

non-contact 3d surface roughness measurement
The standard deviation of peak heights could certainly be calculated from 3D data sets. However, the challenging part is in the determination of "what defines a peak". Is it any local maxima, regardless of its position? Then you would have to count a small bump in the bottom of a pit. Is...- mcmalburg
