Very flat outside corners
Where outside corners are very flat, the response with
G450
(transition circle) and
G451
(intersection) becomes increasingly similar. In this case, it is no longer advisable to insert a
transition circle. One reason why it is not permitted to insert a transition circle at these
outside corners with 5-axis machining is that this would impose restrictions on speed in
contouring mode (
G64
). Therefore, the system switches automatically from
G450
(transition
circle, with
DISC
where appropriate) to
G451
(intersection) when outside corners are very
flat.
The threshold angle (contour angle) for this automatic switchover (transition circle →
intersection point) can be specified in the machine data:
MD20230 $MC_CUTCOM_CURVE_INSERT_LIMIT (Max. angle for intersection calculation
with tool radius compensation).
