CNC Tooling

[sanddrag]

Although I'm not Cory, we usually put a good size tooling plate (just 6061 plate, about .75" thick or so) in a vise and face mill it to level it out. Then we run a program to drill and tap that fixture plate with our hole locations for our gearbox plate. Then we clamp 1/4" plate to that with little C clamps, then we drill the 1/4" plate only barely through, using the same XY part zero offset. Then we remove the clamps, bolt down the plate, and do all the pocketing and cut the outside profile.
