Surface finish numbering
system
Letter 10073
Regarding surface finish, (RMS), I believe that they are
incremental; for instance a standard callout may be an 8 RMS or a 16
RMS, a 32 RMS, and a 125 RMS.
My question is is an 8 RMS better than a 16 RMS by a certain
percentage? How are these numbers calculated?
