DFM + GD&T DESIGN REVIEW · ASME Y14.5 · UNDER INSPECTION: EM-2117 AFT ENGINE MOUNT

Ship drawings manufacturers accept the first time.

A panel of specialist analyses — cross-examined by an adversarial verification pass, signed off by a mechanical design engineer — returns every defect, every cost trap, and the exact fix. In 24 hours.

FINDING F-001 · CRITICAL
[⊕|Ø0.05Ⓜ|A|B|C]

Position frame on the 8X Ø6.60 flange bolt circle references datum C — never defined anywhere on the drawing. Unmeasurable. Instant shop rejection.

FINDING F-003 · MAJOR

Note 4 demands SHARP (R0) corners in the weight-relief pockets. A rotating tool cannot cut a zero-radius inside corner. As drawn: EDM territory — 10× cost.

FINDING F-004 · MAJOR
Ø14.00 ±0.01

±0.01 mm on the clevis pin bore — tighter than the process holds without honing, and the hard-anodize callout eats the whole band anyway.

FINDING F-023 · MAJOR · CRITIC-FOUND

The STEP model omits the 2X M4 tapped holes called out on the harness bosses. Quote from the model and the holes never get made.

CH.02 — THE CROSS-EXAMINATION

Then our agents attack their own findings.

An adversarial pass re-reads the original drawings and challenges every finding. Unsupported claims get withdrawn. Missed issues get added. Only verified findings reach you.

THE DELIVERABLEWhat lands in your inbox

  • Severity-graded findings — critical / major / minor / info, each with location, evidence, and the exact recommended fix.
  • Cost-reduction opportunities — tolerance relaxations, material substitutions, finish and stock-size savings.
  • Drawing completeness check — the questions a shop would email you, answered before they're asked.
  • Full transparency — withdrawn findings are listed too. You see the rigor, not just the results.

The review of this exact part — intentionally flawed test article.

THE PROCESSThree steps. Twenty-four hours.

  1. 01

    Send your package

    PDF drawings + STEP models — CNC, sheet metal, injection molding, or 3D printing. Fixed quote confirmed before any work starts.

  2. 02

    Panel review + cross-examination

    GD&T per ASME Y14.5, per-process DFM, materials & cost — then the adversarial pass you just watched. A mechanical design engineer signs off on everything.

  3. 03

    Report, fixes, savings

    Severity-graded findings with exact fixes, cost-reduction opportunities, and a completeness check. Standard 24 h; same-day rush available.

PRICINGA review cadence, not a purchase order

Monthly plans for teams that release drawings every sprint — or a single review when one part has to be bulletproof. Independent by design: we don't sell machining, so a shop's "free DFM check" sales filter never touches our findings.

THE ENGINEERReviewed by an engineer, not just software

M3 Solutions is run by Rigo Marulanda, a mechanical design engineer. The AI panel makes the review exhaustive; the adversarial pass makes it honest; the engineer makes it accountable. Nothing reaches you without human sign-off.
