A practical look at why a correct-looking CAD model can still create manufacturing problems, with checks for tolerances, tooling, access, assembly and inspection.
Why Your CAD Model Looks Fine but the Part Fails in Manufacturing Read Post »
A drawing can look complete and still send the wrong information to manufacturing. A missing tolerance, an unclear datum, an outdated revision, or a hole that cannot be inspected can turn a five-minute CAD change into hours of rework. A good mechanical design review is the last practical checkpoint before a model and drawing become
Mechanical Design Review Checklist: 12 Checks Before Releasing a Drawing Read Post »
FEA boundary conditions are one of the most important parts of a finite element model. A fine mesh and powerful solver cannot rescue a model that is restrained incorrectly, loaded unrealistically, or connected with the wrong contact assumptions. This guide shows a practical way to build boundary conditions for a mechanical simulation, using a simple
