finishing

(OP)

Hi all friends,

I need to learn something about finishing.Could you give some information about this sentence ?
" The bore should be finished by techniques known to produce approximately 12rms "
 
Thanks for your interest

RE: finishing

If this is a machined surface finish then it represents roughness in micro inches assuming imperial units. RMS = root mean squared average. 12RMS is fairly smooth and would typically be obtained by grinding.
