Feedrate Control and Spindle Motion
7.1 Feedrate (G93, G94, G95 or F..., FGROUP, FGREF)
Fundamentals

Example of helical interpolation
Path axes X and Y traverse with the programmed feedrate, the infeed axis Z is a
synchronized axis.

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.
