Feedrate G93, G94, G95
All of the commands are modal. If the G feedrate command is switched between G93, G94
or G95 the path feedrate must be reprogrammed. The feedrate can also be specified in
deg/rev when machining with rotary axes.
Feedrate F for path axes
The feedrate is specified with address F. Depending on the default setting in the machine
data, the units of measurement specified with the G commands are either in mm or inch.
One F value can be programmed per NC block. The unit for the feedrate is defined in one of
the above G commands. The feed F acts only on path axes and remains active until a new
feedrate is programmed. Separators are permitted after address F.
Example: F100 or F 100 or F.5 or F=2*FEED
