7.8 Feedrate with handwheel override (FD, FDA)
Path feedrate and enabling of velocity override
with handwheel
<velocity>:
• Value = 0: Not allowed!
• Value ≠ 0: Path velocity
Axial feedrate
<velocity>:
• Value = 0: Path default with handwheel
• Value ≠ 0: Axial velocity
Axis identifier of positioning axis
Path definition: The grinding wheel
oscillating in the Z direction is traversed to
the workpiece in the X direction with the
handwheel.
The operator can continue to feed manually
until the sparks are flying uniformly.
Activating "Delete distance-to-go" switches
to the next NC block and machining
continues in AUTOMATIC mode.
