Operation Manual

330 Teach-in mode
4.8 Milling cycles
Type of machining for technology database access: Milling
Cycle run
1 Activate the C axis and position to spindle angle C at rapid
traverse (only in Teach-in mode)
2 Calculate the proportioning of cuts (infeeds to the milling planes,
infeeds in the milling planes)
3 Move to the safety clearance and plunge to the first milling plane
Roughing
4 Machine the milling plane, taking milling direction J
(unidirectional or bidirectional) into account
5 Plunge to the next milling plane
6 Repeat 4 to 5 until the milling depth is reached
Finishing:
4 Finish-machine the edge of the island—one working plane after
the other
5 Finish-machine the floor from the outside towards the inside
All versions:
6 Position to starting point Z and deactivate C axis
7 Move to the tool change point according to the G14 setting
MFS M at beginning: M function that is executed at the
beginning of the machining step.
MFE M at end: M function that is executed at the end of the
machining step.
WP Displays which workpiece spindle is used to process the
cycle (machine-dependent)
 Main drive
 Opposing spindle for rear-face machining
