Tool offsets

8.10 Compensation at the outside corners (G450, G451)

If the KONTT or KONTC block is the approach block rather than the retraction block, the
contour is exactly the same, but machined in the opposite direction.
8.10 Compensation at the outside corners (G450, G451)
Function
G450/G451 defines the following:
On the one hand, the approach path for active KONT and the approach point behind the
contour (see section "Contour approach and retraction").
On the other hand, the corrected tool path when traveling around outside corners.
Programming
G450 DISC=...
Or
G451
Parameters
G450
DISC=
G451
DISC=... is effective only when G450 is called, but can be programmed in a preceding block
without G450. Both commands are modal.
