HEIDENHAIN TNC 640 User Manual page 191

Fixed Cycles: Pocket Milling / Stud Milling / Slot Milling | POLYGON STUD (Cycle 258, DIN/ISO: G258)
Danger of collision!
The TNC automatically performs an approach motion with this
cycle. A collision may occur if there is not sufficient room.
Specify with Q224 which angle is used to machine the first
corner of the polygon. Input range: -360° to +360°
Depending on the rotary position Q224, the following amount
of space must be left next to the stud: At least tool diameter
+ 2mm.
Danger of collision!
At the end, the TNC positions the tool back to the set-
up clearance, or to the 2nd set-up clearance if one was
programmed. The end position of the tool after the cycle must
not match the starting position.
Control the traversing movements of the machine
In the simulation, control the end position of the tool after the
cycle
After the cycle, program the absolute (not incremental)
coordinates
