Deterministic mechanical pre-review
Challenge the bracket before the drawing is released.
Edit the baseline and candidate geometry. The workbench exposes its screening equations, ranks failure risks, defines critical-to-quality checks, and creates portable review evidence.

Tolerance capability mismatch
44464The stated feature tolerance may be tighter than a routine process can hold without special control or inspection.
3-axis CNC planning floor 0.05 mm vs specified ±0.08 mm. Net-section overload
62448Combined net-section stress and geometric concentration may consume the intended yield margin.
21.7 MPa adjusted stress vs 138 MPa allowable; calculated factor 12.73×. Transition stress concentration
71642A small inside radius relative to stock thickness increases local peak stress and fatigue sensitivity.
Fillet-to-thickness ratio is 0.4; preliminary target is at least 0.30. Hole-edge breakout
71535A short ligament can drive bearing, tear-out, or local deformation at the free edge.
Center-to-edge ratio is 1.8d; this screen uses 1.50d as the preliminary target. Bracket flexibility
51630A tall, thin plate may deflect enough to disturb alignment even when yield strength is acceptable.
Height-to-thickness ratio is 5.4; validate stiffness and interface loads in the assembly model.What the model actually does
Screening math you can challenge.
Net section
σnom = Load ÷ ((Width − Ø) × t)Simple uniaxial screen; it does not model the full assembly load path.
Geometry factor
σadj = σnom × KtKt is a transparent heuristic from edge and fillet ratios, not an FEA solution.
Risk priority
RPN = Severity × Occurrence × DetectionEvery score is traceable to visible evidence and preliminary thresholds.
