Charmille Surface finish

[EricatST]

Can anyone point me at a web page that gives equivalents between Charmille and other types of surface finish.

Thanks

EricatST,

Here is a good place to start.

A Charmille finish is referenced when a certain texture is required when using the EDM (Electronic Discharge Machining) process.

Charmiles surface finishes are metric, the surface finish is directly comparable to RMS. I don't remember the conversion, but it is in the machinist handbook.
