5.1 Entering Tool-Related Data
Feed rate F
The feed rate F is the speed (in millimeters per minute or inches per
minute) at which the tool center moves. The maximum feed rates can
be different for the individual axes and are set in machine parameters.
Input
You can enter the feed rate in every positioning block or in a separate
block. Press the F key on the alphabetic keyboard.
Rapid traverse
If you wish to program rapid traverse, enter F MAX. To enter F MAX,
press the ENT key or the F MAX soft key when the dialog question
FEED RATE F = ?
appears on the TNC screen.
Duration of effect
A feed rate entered as a numerical value remains in effect until a block
with a different feed rate is reached. If the new feed rate is G00 (rapid
traverse), the last programmed feed rate is once again valid after the
next block with G01.
Changing during program run
You can adjust the feed rate during program run with the feed-rate
override knob.
Spindle speed S
The spindle speed S is entered in revolutions per minute (rpm) in any
block (e.g. during tool call).
Programmed change
In the part program, you can change the spindle speed with an S block:
U U U U Press the S key on the alphabetic keyboard.
U U U U Enter the new spindle speed.
Changing during program run
You can adjust the spindle speed during program run with the spindle-
speed override knob.
