Once the feedrate, F, is programmed it remains effective until another
feedrate is programmed (F is modal). You can override programmed
F-words. For details, see chapter 18.

The feedrate for a multi-axis move is specified as the vectorial feedrate.
The control adjusts the individual axis feeds to obtain the programmed
feedrate. For details on feedrates, see chapter 18.
G02 and G03 establish the circular interpolation mode.
In this
mode:
The tool:
G02 moves alonga clockwisearc
G03 moves alonga counterclockwisearc.
Figure 14.3 shows clockwise and counterclockwise orientation relative to
the positive X and Z axes.
