Royce-
      The parts we got from the laser machines were within .002" or better.  
Hole diameters were very accurate to within +- 001".  It really depends a lot 
on the type of material and the setup of the machine.   I have seen the 
results of a wire feed EDM used at the Submarine Repair Facility in Bangor WA 
that held a tolerance of less than .005"  but it was not nearly as fast as 
the laser.
