Mechanical Design Review Checklist Before Manufacturing

Body:
A short design review can prevent expensive rework. Here’s what to check:

The checklist

• Fits & clearances (what can collide?)

• Tolerances (are they realistic and necessary?)

• Materials & finish (availability, corrosion, wear)

• Fasteners (size, grade, access for tools)

• Load paths (where forces actually go)

• Safety factors (document assumptions)

• Drawing clarity (units, notes, revision control)

• Reliability tools for preventing failures.
