I contacted Taylor Hobson because that's who we bought the unit I'm using from and they said 2% if same operator using both units and everything else is exactly the same and 5% if operators are using the same units, spec and trace.
So I wondering how much it would be for different units, I know...
We recently bought Taylor Hobson S-116 profilometer and I am checking some surface finish measurements and comparing them to what the supplier sent and our other labs data and my Ra is within .1 of theirs but my Rz can totally different from theirs, does anyone know why this is?
