Corner behavior: G450, G451
Using the functions G450 and G451, you can set the behavior for non-continuous transition
from one contour element to another contour element (corner behavior) when G41/G42 is
Internal and external corners are detected by the control system automatically. For internal
corners, the intersection of the equidistant paths is always approached.

Transition circle G450
The tool center point travels around the workpiece external corner in an arc with the tool
radius. In view of the data, for example, as far as the feedrate value is concerned, the
transition circle belongs to the next block containing traversing movements.
Point of intersection G451
For a G451 intersection of the equidistant paths, the point (intersection) that results from the
center point paths of the tool (circle or straight line) is approached.
