Range of values: 0, 1, 2 to 100
Significance:
: is used to approach the intersection point of the two equidistant paths in

, but can be programmed in a previous block without
G450
In this example, a transition radius is
programmed for all outside corners
(corresponding to the programming of the
corner behavior in block N30). This prevents
the tool stopping and backing off at the
change of direction.
