Programming technology functions (cycles)
10.1 Drilling
Retraction
Retraction can be realized at the pilot hole depth or the retraction plane.
● Retraction to the retraction plane is realized with G0 or feedrate, programmable speed as
well as direction of rotation respectively stationary spindle.
● For retraction at the pilot hole depth, subsequent retraction and insertion are performed
with the same data.
Note
Direction of spindle rotation
The direction of spindle rotation is not reversed; however, where necessary, can be stopped.
Coolant
The technology and tools require that also in the G code, the control for the coolant is
supported.
● Coolant on
Switch on at Z0 + safety clearance or at the pilot hole depth (if a pilot hole is being used)
● Coolant off
● Programming in the G code
An executable block (M command or subprogram call), which can be programmed as string.
