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 point 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 the T block and in every positioning
block (see "Programming tool movements in DIN/ISO format" on
page 100). In millimeter-programs you enter the feed rate in mm/min,
and in inch-programs, for reasons of resolution, in 1/10 inch/min.
Rapid traverse
If you wish to program rapid traverse, enter G00.
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 F.
