Programming cycles

C a ll and return conditions
The G functions effective prior to the cycle call and the programmable offsets remain active beyond the cycle.
The machining level (G17, G18, G19) must be defined before calling the cycle. A cycle operates in the current plane with:
● First axis of the plane (abscissa)
● Second axis of the plane (ordinate)
● Drilling axis/infeed axis, third axis, standing vertically to the plane (vertical infeed axis)
With drilling cycles, the drilling operation is carried out in the axis standing vertically to the current plane. In milling, the depth
infeed is carried out in this axis.
See the following illustrations for plane and axis assignment:

Me ssages output during execution of a cycle
Messages that refer to the state of machining are displayed on the screen of the control system during program execution.
These messages do not interrupt the program execution and continue to be displayed on the screen until the next message
appears.
The message texts and their meaning are listed together with the cycle to which they refer.
Bl ock display during execution of a cycle
During the cycle execution, the cursor is always located on the program blocks of the cycle.
C ycle call and parameter list
The defining parameters for the cycles can be transferred via the parameter list when the cycle is called.
N o te
Cycle calls must always be programmed in a separate block.
