Tool alignment for turning

The input fields for the β and γ angles for aligning the tool are available in the tool screen and
in all turning screens.
β angle
In the entry field "β" you have the possibility of selecting the main alignment of the tool:
●
●
●
Programming when machining with a counterspindle
When machining on the counterspindle, it is programmed in exactly the same way as the main
spindle.
The direction display of the arrows depends on the settings.
γ angle
In the entry field "γ" you have the possibility of selecting the main alignment of the tool:
● 0°
● 180°
- or -
● Free entry field to enter the required angle
17.3 Milling with a B axis
No special entries are required for face machining and peripheral surface machining.
Face machining
Milling at the face (G17) is realized on the main spindle in the B axis position B = 0°. If you are
machining at the face (G17) of the counterspindle, then this corresponds to the opposite setting
of the B axis position B = 180°.
Peripheral surface machining
Milling on the peripheral surface is always realized in the B axis position, B = 90° (main and
counterspindle).
