Run the drilling cycle on the defined pattern:
Confirm Feed rate F=? with the ENT key: Move at
rapid traverse ( FMAX)
Miscellaneous function M? Switch on the spindle
and coolant, e.g.
M13. Confirm with the END key:
The TNC saves the entered positioning block
Z
Enter Retract the tool: Press the orange axis key
Z
in order to get clear in the tool axis, and enter the
value for the position to be approached, e.g. 250.
Confirm with the
ENT key
Confirm Radius comp.: R+/R-/no comp.? by
pressing the
ENT key: Do not activate radius
compensation
Confirm
Feed rate F=? with the ENT key: Move at
rapid traverse (
FMAX)
Miscellaneous function M? Enter M2 to end the
program and confirm with the
END key: The TNC
saves the entered positioning block
