The cycle is machine-dependent.

To be able to perform a turning operation, you need to position the tool appropriately relative to the turning spindle. For this purpose, you can use Cycle 800 ADJUST XZ SYSTEM.
With turning operations, the inclination angle between the tool and turning spindle is important, in order to e.g. machine contours with undercuts. Cycle 800 provides various possibilities for aligning the coordinate system for an inclined machining operation:
- If you have positioned the tilting axis for inclined machining, you can use Cycle 800 to orient the coordinate system to the positions of the tilting axes (Q530=0). In this case, make sure to program M144 or M128/TCPM for proper calculation of the orientation
- Cycle 800 calculates the required tilting axis angle based on the inclination angle Q531 − depending on the strategy selected in the INCLINED MACHINING Q530 parameter, the control positions the tilting axis with (Q530=1) or without compensating movement (Q530=2)
- Cycle 800 uses the inclination angle Q531 to calculate the required tilting axis angle, but does not position the tilting axis (Q530=3). You need to position the tilting axis manually to the calculated values Q120 (A axis), Q121 (B axis), and Q122 (C axis) after the cycle
If the milling spindle axis and the turning spindle axis are parallel to each other, you can use the Precession angle Q497 to define any desired rotation of the coordinate system about the spindle axis (Z axis). This may be necessary if you have to bring the tool into a specific position due to space restrictions or if you want to improve your ability to observe a machining process. If the turning spindle and milling spindle axes are not parallel, only two precession angles are realistic for machining. The control selects the angle that is closest to the input value of Q497.
Cycle 800 positions the milling spindle such that the cutting edge is aligned relative to the turning contour. You can use a mirrored version of the tool (REVERSE TOOL Q498); this offsets the milling spindle by 180°. In this way, you can use your tools for both inside and outside machining. Position the cutting edge at the center of the turning spindle using a positioning block, such as L Y+0 R0 FMAX.
- If you change the position of a tilting axis, you need to run Cycle 800 again to align the coordinate system.
- Check the orientation of the tool before machining.
