Measuring angular offset during spindle
synchronization G906
G906 writes the angular offset between the master spindle and the
slave spindle into variable V921.
Programming:
„ Program G906 only for active angular synchronization – both chucks
must be closed.
„ Program G906 in a separate NC block.
„ Program a G909 (interpreter stop) before processing V921.
„ G906 generates an interpreter stop
Traversing to a fixed stop G916
G916 activates the monitoring function for the traversing path. Then
you move with G1 to a fixed stop. User G916 for:
„ Traversing to a dead stop (example: transferring a premachined
workpiece to a second traveling spindle if you do not know the exact
position of the workpiece).
„ Press the tailstock against the workpiece (tailstock function)
The CNC PILOT stops the slide and saves the stop position. G916
generates an interpreter stop.
Traversing to a fixed stop (G916 without parameters). The CNC
PILOT
„ moves up to the fixed stop and stops as soon as the servo lag has
been reached. The remaining path of traverse is deleted.
„ saves the position of the fixed stop in variables V901 to V918.
„ move back by the servo lag + reversing path (MP 1112, 1162, ..).
In MP 1112, 1162, .. you specify:
„ Lag error limit
„ Reversing path
Parameters
H Clamping force in daNewtons (1 daNewton = 10 newtons)
D Mode:
„ D=1: Activate tailstock function.
„ D=2: Deactivate tailstock function.
As of software version 625 952-04:
„ D=3: Do not issue message when end point is reached
R Reversing path
