  1. When facing with a superfly on aluminum, use 2500 RPM, 12 ipm
  2. When facing with a 1/2" on aluminum, use 5000 RPM, 12 IPM
  3. If you have a tall, thin piece of stock, stabilize it on either side with 1-2-3 blocks and face with an endmill to reduce chatter
  4. When cutting a thin plate of aluminum stock, tools like the 1/2" and the shear hog will induce too much pressure and cause chatter. This can be prevented by performing your adaptive and contour operations with a small bit such as a 3/16".

Always reference Z first
