"Clean-Up 80%" stated on a drawing
(OP)
I am currently working contract at a company that used to have their own machine shop, but closed it and are now are sending the work to outside sources.
I am looking at one of their drawings, which is a machined weldment drawing for a very large (7000 lb) part.
In one of the views there is a note pointing to a specific machined region stating . . . CLEAN-UP 80% . . .
What does that mean ?
I am wondering if it is something that the guys in their former shop knew the meaning, or if it is a common term, because I am preparing a drawing to be sent out.

It is not common to use this but I have seen it on some prints over the years.

The 80% says that on a 10 x 10 inch plate (100 sq inches) 80% (80 sq in) must be cleaned by the mill or turning process. If one corner is a little lower that the rest of the surface it will not affect the installation.
