Surface Finishes by Tolerance
Hi, I'm new to the forum.
Years ago I found a handy chart where it stated the average surfaces finish by the tolerance of the feature. I've been looking in the internet, but I can't find any such chart again. Everything I'm seeing on the internet is finish range by a machining process. An example of what I'm looking for is:
±.005 = 125 RMA
±.001 = 64 RMA
±.0005 = 32 RMA.
These are not the actual values, but rather my best guess. I was looking for a chart to validate.
