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", page 91). 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.
