Offset C angle G905
G905 measures the angular offset of workpiece transfer with
rotating spindle. The sum of Angle C and the angle offset goes into
effect as the datum shift of the C axis. If you request the datum
shift of the current C-axis in the variable #a0 ( C,1) the sum of
the programmed datum shift and the measured offset angle is
transferred.
The datum shift is effective internally as a direct datum shift for the
respective C axis. The contents of the variables are retained even if
the control has been switched off.
You can also examine and reset the respectively active datum shift
of the C axis in the Setup menu in the Set C-axis values function.
Parameters:
Q: No. axis C
C: Angle – angle of additional datum shift for offset gripping
(range: –360° <= C <= 360°; default: 0°)
NOTICE
Danger of collision!
When switching off the control and when switching the
operating mode (e.g. between Machine operating mode and
Program run submode), datum shifts of the C axis are retained.
Danger of collision during subsequent machining operations or
workpiece transfers!
Always intentionally switch off datum shifts of the C axis
NOTICE
Danger of collision!
The control does not check for jaw collisions during workpiece
transfer (e.g. between the main spindle and counter spindle).
Danger of collision with short workpieces during transfers!
Inspect the datum shift of the C axis and reset if required to
ensure offset gripping of the jaws
