Climb Milling versus Conventional Milling [ Sneaky CNC ...

Climb Milling = Down Milling. Conventional Milling = Up Miling. Climb milling is when the direction of cut and rotation of the cutter combine to try to "suck" the mill up over (hence it's called "climb" milling) or away from the work. It produces the best surface finish. Here is a diagram showing climb versus conventional milling for ...
