(OP)
Folks-
It seems that everybody I talk to has a different opinion on what positional and profile tolerances can be held by different processes for producing feature patterns and outlines in metals and PCBs.

Where can I find, say, A.  difficult, B. somewhat difficult, C. typical, and D. "no-brainer"
i.  in-pattern (feature-relating) tolerances and
ii. pattern-locating tolerances.

1.  punching,
2.  machining,
3.  Waterjet,
4.  EDM, and
5.  Laser

in:

a.  plastic sheets and plates (various kinds, thermoset, thermoplastic, fiber reinforced,...)
b.  sheet metal (various alloys, ferrous and non-ferrous)
c.  metal plate (various alloys, ferrous and non-ferrous)
c.  metal bar stock (varous alloys, ferrous and non-ferrous)

I'm really looking for publications not opinions.  Also, assume all processes are CNC-driven.  We would never buy from somebody with a manually-controlled equipment.
