SURFCAM creates toolpaths by creating offsets from the contour or sides of a part. The offsets around a corner angle will be two lines that may or may not intersect.
The Sharp Corner Angle parameter tells SURFCAM how to fill the offset gap when a sharp corner angle is between 5° and 160°.
5° < Corner Angle < 160°
If a corner angle is in the range of 5° to 160° and is greater than the value you enter for Sharp Corner Angle, SURFCAM will extend the offsets so they intersect at a point.
If a corner angle in this range is less than or equal to the value you enter for Sharp Corner Angle, SURFCAM will close the offset gap with two lines, an arc, or a loop— depending on your selection of Sharp, Round, or Loop for the Sharp Corner Type parameter on the Cut Control tab.
Notes
Corner Angle
> 180°
The offsets intersect. The wire path will change linear direction at the
intersection.
160° <
Corner Angle < 180°
Offsets of corner angles between 160° and 180° will not intersect, but
SURFCAM will automatically extend them so they do. The toolpath will then
change direction at this intersection.
Corner Angle
< 5°
SURFCAM will close the gap between the two offsets by inserting an arc.
