Refer to your machine manual.
This function must be enabled and adapted by the machine manufacturer.

For the cycles, option 157 Gear Cutting is required. If you would like to use these cycles in turning mode, you also need option 50. In milling mode, the tool spindle is the master spindle, in turning mode, it is the workpiece spindle. The other spindle is called slave spindle. Depending on the operating mode, you program the speed or the cutting speed with a TOOL CALL S or FUNCTION TURNDATA SPIN.
To orient the I-CS coordinate system, Cycles 286 and 287 use the precession angle that is also affected by Cycles 800 and 801 in turning mode. At the end of the cycle, the control resets the precession angle to its state at the beginning of the cycle. If one of these cycles is aborted, the precession angle will also be reset.
The axis crossing angle is the angle between workpiece and tool. It results from the angle of inclination of the tool and the angle of inclination of the gear. Based on the required axis crossing angle, Cycles 286 and 287 calculate the required inclination of the rotary axis at the machine. The cycles will always position the first rotary axis starting from the tool.
In order to ensure that the tool can safely be retracted from the gear in the event of a fault (NC stop or power failure), the cycles automatically control the LiftOff. The cycles define the direction and path for a LiftOff.
The gear itself will first be described in Cycle 285 DEFINE GEAR. Then, program Cycle 286 GEAR HOBBING or Cycle 287 GEAR SKIVING.
Program the following:
- Call a tool with TOOL CALL
- Select turning mode or milling mode, with FUNCTION MODE TURN or FUNCTION MODE MILL "KINEMATIC_GEAR" kinematics selection
- Spindle direction of rotation (e.g., M3 or M303)
- Perform pre-positioning for the cycle depending on your selection of MILL or TURN
- Define the CYCL DEF 285 DEFINE GEAR cycle
- Define the CYCL DEF 286 GEAR HOBBING or CYCL DEF 287 GEAR SKIVING cycle.
