Reverse Engineering

No drawing?
Bring the part.

We’ll scan it, model it, and make it.

FJM Manufacturing offers 3D scanning and reverse engineering in Nashua, New Hampshire. Bring a worn, broken or obsolete part with no drawing and no CAD model, and we will capture the geometry, produce the model, and machine the replacement.

The situation

When the drawing no longer exists

A machine goes down. The part that failed was made twenty years ago by a company that no longer exists, or it was custom, or the drawing went missing three owners back. The OEM quotes sixteen weeks, or simply does not answer.

Most machine shops need a drawing before they will quote. That is a reasonable position — producing geometry from a physical object is a different skill from cutting to a print — but it leaves you with nowhere to go.

Send the part here instead. Even a worn or broken one usually carries enough information to reconstruct what it was when it left the factory.

How it works

From part to part

1. Scan and measure

The part is 3D scanned and measured directly, capturing the geometry including features no drawing ever recorded.

2. Model and interpret

Wear is backed out and intent reconstructed — deciding what a dimension was meant to be is the part that takes judgement.

3. Machine and verify

Cut, then inspected against the reconstructed model. Fixtures are kept in case you need more later.

Specifications

Tolerances and inspection

Tolerances held to ±0.0001″ on critical features. Every part is inspected against print before it ships — 100% inspection, not sampling — on a granite surface plate with a TESA height gauge.

What comes with the work

Materials

Aluminum 6061 and 7075. Stainless 303, 304, 316, 420, 440 and 17-4 PH. Carbon steels and mold steels. Titanium. Brass, bronze and copper. Engineering plastics including Delrin, PEEK, UHMW and PTFE.

FAQ

Common questions

No. That is the point of this service. Send the physical part and we will produce the geometry from it.

Usually still workable. A broken part can often be measured across the fracture, and wear can be backed out to reconstruct the original dimensions. If there genuinely is not enough left, we will tell you rather than guess.

Often, yes. If a part always fails in the same place, that is usually a material or geometry issue and worth discussing before the replacement is cut.

Quotes come back the next business day, and rush service is available including next-morning turnaround on suitable jobs.

Yes. The model and any fixture are retained, so a repeat order is far quicker and cheaper than the first.
