Surface roughness and wavyness transform
Surface roughness and wavyness transform
(OP)
I have an excel file with surface height measurements taken with a laser gauge. There are ~17000 measurements taken at .5 micron spacing. I want to calculate various surface finish parameters from this data. Does anyone know of an add in package of excel functions give outputs of Ra, Rmax, waviness, etc?
Basically, I want to do all math functions on this data that a surface texture instrument does.

People that might have something probably consider it somewhat proprietary.

You can apparently download a 30-day trial for this package:

You might be able to use the NIST virtual calibration site to see what their algorithm says: http://syseng.nist.gov/3DVSC/jsp/FileOpen3D.jsp
