Does anyone know of a usable guide that spells out the rules for assigning reference designators in documentation? I know I can buy IEEE-315 but that is so formal and nebulous that it only leads to confusion! Thanks!

Does anyone know of a military or government standard that controls TGIC Polyester powdercoating? Thanks for taking a look!

Our company has a boilerplate note on our fabricated metal drawings that says: DEBURR HOLES AND BREAK SHARP EDGES. Is it true that only drilled holes have "burrs" and that we need to "break" only edges to eliminate cutting hazards? Comments?

Thank you BillPSU and dvd! Good ideas. I'll run with them.

mncad- I should mention that the pattern need not be "machined" per se.

mncad- The parts are small: 1" X 2.5" x 4" with a .5 x 1" x 2" recess inside. As for processes, we have only a small shop for prototyping. We outsource our fabricated metal parts.

Thanks. What I failed to mention is that the surface is at the bottom of a recess. This would mean that only the middle part of the surface could be reached with the roller. Any other ideas?

I know this can be done on a cylindrical surface (knurling) but what about a flat surface? I'm aware of the availability of tread plate but my part is substantially thick and the value (and quantity) is not enough to justify casting. Thanks!
