When you group 6 cabinets together in the same group to be sent to the saw/routers, the different parts of those 6 cabinets get put on the sheet stock to maximize yield.  That usually ends up with the parts for one cabinet spread over several sheets. 

Are there any tricks that you can use to make it easier to sort parts as they come off a saw or CNC router so that you can get all of the parts for cabinet 1 on one skid and all of the parts for cabinet 2 on another?

Maybe color code the labels or the ink some how?
