Feedrate Control and Spindle Motion
7.1 Feedrate (G93, G94, G95 or F..., FGROUP, FGREF)
Fundamentals
274 Programming Manual, 11/2006, 6FC5398-1BP10-2BA0
Caution
The FGREF evaluation also works if only rotary axes are programmed in the block. The
normal F value interpretation as degree/min applies in this case only if the radius reference
corresponds to the FGREF default, when
G71/G710: FGREF[A]=57.296
G70/G700: FGREF[A]=57.296/25.4
Units of measurement and calculation
Machine manufacturer
See machine manufacturer's specifications.
Units of measurement for feedrate F
You can use the following G commands to define the units of measurement for the feed
input. Feedrate functions are not affected by G70/G71.
Note
With G700/G710, feedrate values F are interpreted as geometrical parameters in the
measuring system set by G function (G700: [inch/min]; G710: [mm/min]).
Feedrate G93
Unit 1/rpm. The inverse-time feedrate specifies the time required to execute the motion
commands in a block.
Example: N10 G93 G01 X100 F2 means: the programmed path is traversed in 0.5 min.
