Corner Condition Types
Corner conditions can be specified for the vertices of the cut motion created using the Edge or Curve option, to avoid gouging sharp corners. Wherever a corner condition is added, a small parallelogram will be incorporated in the cut motion: the tool will continue moving along the first entity, then return to enter tangent to the second entity. The size of the parallelogram is defined by the path parameter CORNER_LENGTH.
If you add a corner condition along an entity or between two tangent entities, the angle of the parallelogram will be defined by the CORNER_ANGLE parameter; if the condition is at a vertex and the corner is sharp, the CORNER_ANGLE value will be ignored and the sides of the parallelogram will be formed as a continuation of the adjoining entities.
The following graphic illustrates the CORNER_LENGTH and CORNER_ANGLE parameters.
The following corner condition types are available:
Straight—Create a straight corner condition.
Concave—Create a round corner motion for a corner that is concave.
Convex—Create a round corner motion for a corner that is convex.
Chamfer—A chamfer whose size is defined by the CHAMFER_DIM parameter, which represents the distance cut on each side of the corner.
Bisect—The tool makes a straight cut into the material, bisecting the angle between adjacent (non-tangent) edges. The length of the cut is defined by the CORNER_LENGTH parameter. Cutter compensation will be turned off for the corner creation motion and reactivated for the continuation of cut motion. This type of corner is used to allow the part to flex and spring back during subsequent assembly.
Fillet—Create a fillet corner motion.
Loop—Create a loop corner motion. Available for convex corner conditions only.
