Datum structure
We identify datum references, feature control frames and material condition notes that drive fixturing, machine setup and inspection sequence.
Fanuc Cnc uses this page as the technical center of the site because authority-expert buyers need to see how documentation is created. The service begins with drawing interpretation, controller context and the release question. Is the buyer validating a prototype, replacing a machine component, supporting repeat production or preparing a formal submission packet? Each answer changes the evidence that belongs in the quote.
The goal is not to bury the buyer in paperwork. It is to name the correct paperwork before the purchase order is placed. When GD&T is ambiguous, the quote should say so. When FAI is required, the balloon map and dimensional report scope should be planned. When PPAP is needed, the submission level, control plan and capability expectations should be visible.
We identify datum references, feature control frames and material condition notes that drive fixturing, machine setup and inspection sequence.
Dimensions that affect safety, fit or performance are separated from lower-risk features so the buyer can assign evidence where it matters.
Fanuc Cnc states whether caliper, gauge, CMM, optical or functional checks are appropriate for the requested evidence level.
The review also protects both sides from unrealistic assumptions. A drawing may call for tight position tolerance without a clear datum scheme, or a surface requirement may conflict with the material and process route. Fanuc Cnc flags those points before price and lead time become fixed. Buyers can then revise the print, approve an assumption or choose a higher evidence level with clear cost impact.
| Balloon drawing | Features numbered against the print revision and inspection record. |
|---|---|
| Dimensional report | Measured results, method notes and out-of-tolerance disposition where applicable. |
| Material evidence | Certificate expectations documented before shipment. |
| Change record | Revision, deviation or concession notes kept with the release file. |
For aerospace-style requirements, the packet can be aligned to AS9102 expectations. For other industries, the same discipline can be scaled down to a buyer-specific first-article format. The important point is that the evidence is discussed before manufacturing begins, so inspection time, sample handling and review responsibility are not discovered at the dock.
Clarify whether the buyer needs a limited dimensional package or a fuller PPAP record.
Define in-process checks, sample frequency and reaction plan for repeat production.
Identify which characteristics justify capability tracking after the process is stable.
Track open issues by owner, root-cause status and due date before release.
Fanuc Cnc will return an evidence path that separates quote assumptions, inspection cost and release timing.
