Dear,

I have developed peripheral roughness on cross sections of wires 20 years ago, as we follow up roughness of wires during wire drawing process.
All you need is a profile in x,y coordinates in a calibrated image.
Further processing  like cut-off filtering and parameter selections  like Ra, Rt, waviness and others I do with profession software license like Omnisurf, which  is very good and not expensive license.

Hope this helps you further.

Kindest regards,

Martin.

Subject: Roughness from cross-section image

Hello all,

My problem should be relatively simple to solve, but was not able to find it or to find a solution on the forum. I have a coating that was cut and polished and prepared in cross-section. What i want to do is to measure the roughness of that coating using ImageJ in this cross-section image. Any thoughts on how this could be done?

I tried to use the wand tool to define the outer part of the coating with success but then i need to take out the x,y values of only the wand selection cutter part. With this i might try to do a linear interpolation and afterwards measure the roughness. But i was not able to take out the coordinates of the wand selection.

Any other thoughts?

Thank all
