Hiding cycle parameters

The documentation describes all the possible input parameters for each cycle. Depending on
the settings of the machine manufacturer, certain parameters can be hidden in the screens,
i.e. not displayed. These are then generated with the appropriate default values when the
cycles are called.

Call and return conditions for cycles

● Before the call, the tool offset of the tool being used must be selected.
● The appropriate values for feedrate, spindle speed and direction of spindle rotation must
● The spindle commands always refer to the active master spindle. If necessary, this must
● The G functions active before the cycle call and the programmable frame remain active
● The starting position must be approached in the higher-level program before the cycle is

Cycles for single position or position pattern (MCALL)

Drilling and milling cycles can be programmed either for a single position, or used on a
position pattern.

called. The coordinates are programmed in a clockwise coordinate system.
Program a single drilling position or a reference point for milling cycles.
First you program the technology blocks, exactly in the sequence required
for the machining, e.g.
– Centering with tool and input of spindle speed and machining feedrate
– Drilling with tool and input of spindle speed and machining feedrate
– Reaming with tool and input of spindle speed and machining feedrate
or
– Drilling with tool and input of spindle speed and machining feedrate
– Tapping with tool and input of spindle speed and
