Sending this from my Omax 55/100 controller. 5 axis waterjet cutting is quite specialized for certain applications. Most the time Milling operations are a much more accurate and efficient alternative. We have seen some instances where weld prep on production level jobs is a good fit. You should see very little taper in your cuts if the machine is properly set up. We cut .250, Al, Steel and Cu to within +- .003 regularly.We can cut 4.00 steel plate +-.030.
