Fillet the base of ribs and bosses so stress and flow do not spike at the root
Rule Card¶
| Field | Value |
|---|---|
| Pack | G_BASELINE — DFM Baseline Codex |
| Title | Fillet the base of ribs and bosses so stress and flow do not spike at the root |
| Severity | major |
| Check logic | Hybrid |
| Applies to | CAD part, CAD wall feature |
| Inputs required | wall_thickness_map, radii_set, geometry_features |
| Fix template | Add or tune the root fillet so the feature carries load and flow smoothly without creating a thick sink-prone section. |
Short Description¶
A root fillet removes the sharp stress raiser at the rib or boss base and improves flow and cooling. Too little radius concentrates stress; too much creates a thick section.
When It Applies¶
This rule belongs to G_BASELINE (Shared across multiple manufacturing routes) and targets CAD part, CAD wall feature.
