Salvagnini DFM, GD&T and Release Documentation Services

Engineering services turn an RFQ from a price request into a controlled manufacturing plan. Salvagnini reviews the drawing, identifies the risk, defines the evidence path and keeps each technical decision attached to the program record.

DFM review path

From STEP file to documented route in four gates.

Gate 1

File inventory

STEP, DXF, PDF, PMI and revision notes are checked for consistency. Missing datums, ambiguous material notes and conflicting bend callouts are listed before quote release.

Gate 2

Tolerance risk

Critical features are mapped to fixture strategy, machine access, inspection method and expected process capability. Features that cannot be verified are escalated.

Gate 3

Approval stack

The team defines whether the program needs AS9102 FAI, PPAP Level 3, material certificates, coating certificates, CMM reports or customer-specific forms.

Gate 4

Route release

The manufacturing route, hold points, inspection checkpoints and documentation owners are locked before purchasing, scheduling or tooling work begins.

GD&T interpretation

Datum schemes are reviewed against real inspection access.

A drawing may be technically complete and still create production risk. Salvagnini reviews position tolerances, profile controls, flatness, perpendicularity, surface finish and edge-break notes against how the feature will be machined, bent, welded, coated and measured. This is especially important for laser machinery parts, press brake tooling and equipment modules where fabricated geometry and machined interfaces meet in the same assembly.

The review does not replace the customer's design authority. It gives the buyer a practical manufacturing interpretation, identifies where clarification is required and prevents unmeasurable requirements from being discovered at final inspection.

Evidence packages built around the buyer's approval route.

AS9102 FAI

Ballooned drawing, characteristic list, measurement results, material evidence and sign-off fields prepared for aerospace-style first article review.

PPAP Level 3

Process flow, PFMEA extract, control plan, dimensional results, material records and PSW support for production approval workflows.

Metrology evidence

CMM report, scan overlay, gauge method or visual criteria selected according to feature risk and customer acceptance language.

The engineering services page exists because regulated buyers often need a technical conversation before a commercial conversation. A supplier that cannot explain how it will inspect the part, document the route and control revision changes is not ready for the purchase order. Salvagnini's engineering desk gives sourcing teams a way to resolve those questions early.

Technical file review

Start with the drawing set and the approval checklist.

Send the file package, target industry, tolerance concerns and required forms. Salvagnini will identify missing engineering inputs before the RFQ turns into a schedule risk.
