Tooth Feedrate (G95 Fz) - Siemens Sinumerik 840D sl Programming Manual

Feed control

8.12 Tooth feedrate (G95 FZ)

Note
If no traversing motion is programmed in the block (e.g. computation block), the FB has no
effect.
If no explicit feedrate for chamfering/rounding is programmed, then the value of FB also applies
for any chamfering/rounding contour element in this block.
Feedrate interpolations FLIN, FCUB, etc. are also possible without restriction.
Simultaneous programming of FB and FD (handwheel travel with feedrate override) or F (modal
path feedrate) is not possible.
