An F--word with numeric values specifies feedrates for the cutting tool in
linear interpolation (G01), and circular interpolation (G02/G03) modes.
The feedrate is the speed along a vector of the commanded axes, as shown
in the following figure.

The term “feed”refers to moving a tool at a specific velocity in a cutting
path. “Feedrate”is the velocity programmed for the feed of a tool.
Feedrates a re expressed by the distance of movement per interval.
Depending on the mode of the control and the results wanted, the distance
can be millimeters, inches, meters, or revolutions. The interval can be
minutes or revolutions.
