Surface Finishes
Surface Finishes
(OP)
I have a drawing that specifies a surface finish of "12.5s". I have heard of Ra, Rms, etc. but I have not heard of the "s" designation. Can anyone tell me where I can learn more about this? I've looked all over and cannot find anything.
Thanks
Thanks





RE: Surface Finishes
"S" is usually defineed as the length of measurement over which a roughness trace is taken.
Hope this helps
