Handling Unexpected Feature ID Results

Design Advisor relies on generating a complete and accurate analysis of the machinable features on your part. If Design Advisor did not accurately identify all of the features on your part, please let us know.

Here are a few common issues that can cause unexpected feature ID:

Chamfer shown as Contour Surface

This can occur when a modeled chamfer does not have a consistent angle across the length of the chamfer, unintentionally creating swarf geometry. This would need to be surfaced to be machined as modeled on a three-axis milling machine.

Chamfer shown as Slanted Face

This occurs when a chamfer has no bends, and is not a problem.

Small Nonstandard Chamfers at Triple Edge Intersections

When three faces come together at a sharp corner, if each edge has a chamfer applied then a small extra chamfer at the "triple corner" may be present. This chamfer will have a different angle and may not be easily machined as modeled.

For example, when three 45 degree chamfers converge, a 35 degree corner chamfer may be modeled.

Pocket shown as Contour Surface

The wall of a pocket can be designed with a shallow (and nearly imperceptible) draft angle. Since pockets are required to have vertical walls relative to the machining axis, this causes drafted pockets to be classified as freeform contour surfaces.
