CAM Pocketing/Contouring Methods

[Cory]

My defaults for a 1/4" 3 flute tool in 1/4" aluminum are 40% radial cut width at full depth when pocketing. You should be able to do the same, albeit at a lower feed since you have a slow max spindle speed. The main limiting factor here is ability to clear chips so you are not recutting them.
