1. Measurement
Every feature is captured with calibrated gauges, CMM, or optical measurement. Threads, bores, fits, and datums get special attention because they determine whether the part works.
2. Material identification
The shop determines the alloy or plastic, plus any heat treatment, plating, or coating. Wrong material is the most common reason a copied part fails early.
3. Design intent, not wear
A worn part is not the drawing. Good reverse engineering reconstructs the nominal dimensions and tolerances the designer intended, checked against the mating parts.
4. A drawing you keep
The result is a proper drawing, so the part can be remade, improved, or quoted by anyone in the future.
5. First article and fit check
The first piece is inspected and fit-checked in the real assembly before a batch or spares are made.
What to send the shop
- The part (broken is fine) or 3–5 clear photos with a ruler in frame
- Machine make, model, and approximate age
- What the part does and how it failed
- How many you need now and as spares
