I am trying to use surfcam truemill to machine a 3.625 deep pocket
can anyone help me with the proper depth of cut i should take along with stepover,feed rates etc..


I will be using a 3 flute high speed steel 1.250 diameter em .190 rad

machining center is an okuma 852v 120 in 50 taper 10,000 rpm max


Its my first time to use truemill so any advice would be helpful

since don't know the material you are cutting, so I recomment 50% stepover of the tool dia and feed .005/.006 per tooth.
