Cycles
9.1 Overview of cycles
The cycles are supplied with the tool box. They are loaded via the RS232 interface into the
part program memory during the start-up of the control system.
Operation while a machining cycle is underway
All cycles are compatible with both automatic infeed and handwheel infeed. You have the
option of interrupting the machining process while it is underway and forcing intermediate
dressing.
Note
The possible operations (e.g. intermediate dressing) are assigned to the keys of the CNC
machine control panel by the machine manufacturer.
Further processing then takes place on the basis of a preliminary dimensional value.
If a cycle is parameterized, then the icons above the parameter sketch will indicate the
corresponding possible operations that are available (see figure below).
