(5)Face milling
Two types of face milling can be performed: face milling with in–feed
machining and face milling without in–feed machining.
When C–AXIS F. MILL is selected on the machining type screen, the
cutting condition screen appears with the prompt “DRIVE...DR = (1:
on 0: off)” displayed. To perform in–feed machining, set 1 for DR.
For details of in–feed machining, see Chapter 7, “IN–FEED
MACHINING BY C–AXIS NOTCHING.”

For face milling types 1 and 3, roughing is performed around a defined
part figure with a clearance for the finish allowance.
