8.2 Parameters
Finishing – Tool tolerances
For tool selection, the following applies:
 Tool angle (EW): EW >= mkw
(mkw: ascending contour angle)
 Tool angle (EW) and point angle (SW):
NWmin < (EW+SW) < NWmax
 Adjacent angle tolerance (FNWT): FNWT = NWmax – NWmin
Finishing – Tool tolerances
Approach and departure are at rapid traverse (G0).
To ol to l er an c es
Adjacent angle tolerance [FNWT]
Tolerance range for secondary cutting edge
Relief cutting angle [FFW]
Minimum angle differential between the contour and
secondary cutting edge
Approach and departure
 Approach – external finishing [ANFA]
 Approach – internal finishing [ANFI]
 Departure – external finishing [ABFA]
 Departure – internal finishing [ABFI]
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
