Corner behavior: G450, G451
Functionality
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 active.
Internal and external corners are detected automatically by the control system. For internal corners, the intersection of the
equidistant paths is always approached.
See the following illustration for corner behavior at an external corner:
See the following illustration for corner behavior at an internal corner:
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.
