cles
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).
Contour milling:
3 Depending on "R," approach the workpiece and plunge to the first
milling plane.
4 Mill the first plane.
5 Plunge to the next milling plane.
6 Repeat 5 to 6 until the milling depth is reached.
7 Position to starting point Z and deactivate C axis.
Pocket milling—Roughing:
3 Move to the safety clearance and plunge to the first milling plane.
4 Depending on "J," machine the milling plane either from the inside
towards the outside, or vice versa.
5 Plunge to the next milling plane.
6 Repeat 4 to 5 until the milling depth is reached.
7 Position to starting point Z and deactivate C axis.
Pocket milling—Finishing:
3 Depending on "R," approach the workpiece and plunge to the first
milling plane.
4 Finish-machine the edge of the pocket—one working plane after
the other.
5 Depending on "J," finish-machine the milling floor either from the
inside towards the outside, or vice versa.
6 Finish-machine the pocket at the programmed feed rate.
7 Position to starting point Z and deactivate C axis.
