Milling – Safety clearances and oversizes
Approach and departure
 Approach – end face [ANMS]
 Approach – lateral surface [ANMM]
 Departure – end face [ABMS]
 Departure – lateral surface [ABMM]
Approach/departure strategy:
 1: Move simultaneously in X and Z directions
 2: First X, then Z direction
 3: First Z, then X direction
 6: Coupled motion; X precedes Z direction
 7: Coupled motion; Z precedes X direction
