Rules

Rule Title Severity Logic Applies to References
DBC-001 Keep nominal wall thickness as uniform as practical and taper transitions gradually major Deterministic CAD part, CAD wall feature REF-BOOK-DFM-SUCCESS, REF-BOOK-DFM-INJECTION
DBC-002 Avoid sharp internal corners; use generous radii so material and tools can move smoothly major Deterministic CAD part, CAD pocket feature, CAD wall feature REF-BOOK-DFM-SUCCESS, REF-BOOK-DFM-INJECTION
DBC-003 Make features reachable in the preferred manufacturing direction major Hybrid CAD part, CAD pocket feature, CAD hole feature REF-BOOK-DFM-SUCCESS
DBC-004 Keep turned parts stubby enough to resist deflection during cutting major Hybrid CAD part REF-BOOK-DFM-SUCCESS
DBC-005 Keep milled floor-and-wall faces orthogonal when a filleted floor is expected minor Hybrid CAD pocket feature REF-BOOK-DFM-SUCCESS
DBC-006 Size molded ribs and bosses from the nominal wall, not from intuition major Hybrid CAD part, CAD wall feature REF-BOOK-DFM-SUCCESS, REF-BOOK-DFM-INJECTION
DBC-007 Fillet the base of ribs and bosses so stress and flow do not spike at the root major Hybrid CAD part, CAD wall feature REF-BOOK-DFM-SUCCESS
DBC-008 Use draft deliberately on molded pull-direction walls, ribs, and bosses major Hybrid CAD part, CAD wall feature REF-BOOK-DFM-SUCCESS, REF-BOOK-DFM-INJECTION
DBC-009 Treat shut-offs and thin tool sections as durability problems, not just geometry details major Hybrid CAD part REF-BOOK-DFM-INJECTION
DBC-010 Avoid unnecessary undercuts and side actions when simpler geometry can do the job major Hybrid CAD part REF-BOOK-DFM-SUCCESS, REF-BOOK-DFM-INJECTION
DBC-011 Keep molded blind holes short enough that the supporting core pin stays stiff major Deterministic CAD hole feature REF-BOOK-DFM-SUCCESS
DBC-012 Deep narrow features and very sharp mold corners should justify the extra tooling process they force minor Hybrid CAD part, CAD pocket feature REF-BOOK-DFM-INJECTION
