F represents the distance the axis or axes move (in inches or millimeters)
per minute. If the a xis is a rotary axis, the F--word value represents the
number of degrees the axis rotates per minute.
To request a feedrate of 35.5 mm of tool motion per minute, program:

When changing from G93 or G95 modes to G94 mode, an feedrate must be
programmed in the initial G94 block.
Since the G94 c ode is modal, it remains active until canceled by the G93 or
G95 mode. Any F--word programmed while G94 mode is active will be
considered a feed per minute feedrate.
In G95 (feed--per--revolution) mode, the numeric value following the F--
address represents the distance the a xis or axes move (in inches or
millimeters) per spindle revolution. If the axis is a rotary axis, the F--word
value represents the number of degrees the axis rotates per spindle
revolution.
To request a feedrate of 1.5 mm per spindle revolution, program:
G95 G21 F1.5
