Undercut processing

SolidCAM recognizes undercuts in the Hole Feature model.

The SolidCAM AFRM Module analyzes Hole Feature segments in order to find an undercut. An undercut is detected when the diameter increases during one topology segment. The undercut consists of a number of segments and ends when the diameter of the lower undercut segment is equal to or smaller than the Undercut start diameter.

SolidCAM determines the Undercut Height (HU) as the sum of the height of all topology segments of the undercut.

In order for SolidCAM to make the appropriate Undercut substitution, undercuts are classified by the last Hole Feature segment included in the undercut. The classification is as follows:

Undercut – None

In this case, the end diameter of the lower undercut segment is equal to the Undercut start diameter. No segment substitution will be made.

 

Undercut – Planar

In this case Undercut finishes with the Planar Hole Feature segment.

 

Undercut – Cone

In this case Undercut finishes with the Cone Hole Feature segment.

 

Undercut – Chamfer

In this case Undercut finishes with the Chamfer Hole Feature segment.

Undercut – Torus

In this case Undercut finishes with the Torus Hole Feature segment.

Undercut – Sphere

In this case Undercut finishes with the Sphere Hole Feature segment.
