# How to Get an Accurate Aerospace CNC Machining Quote: RFQ Checklist

## TL;DR

- Vendra’s platform and mechanical engineers review your part requirements, identify missing information, and match the work with a suitable U.S. manufacturer. We coordinate quoting, production, inspection, documentation, and delivery.
- Send revision-controlled CAD files and drawings with quantities, forecasts, alloy, material-certificate requirements, critical tolerances, and delivery dates. Complete requirements help manufacturers quote the full scope with fewer assumptions and clarification rounds.
- Specify finishing, heat treatment, inspection criteria, required records, and an AS9102 first article inspection when your program requires one.
- For controlled technical data, confirm recipients, access restrictions, and the transfer method with your export-control team and Vendra before sharing files.
- Check the returned quote against your drawing revision, material, quantities, processes, documentation, setup charges, exclusions, and proposed schedule.

## Why incomplete RFQs lead to inaccurate quotes

An incomplete RFQ leaves a machine shop guessing about the work it must price. A CAD model shows the part’s geometry, but the shop also needs the drawing revision and critical tolerances to plan machining and inspection. If you send an alloy specification without stating the required material certificates, the quote may omit records you need to accept the parts.

Aerospace CNC parts may also require heat treatment, finishing, or special inspection. Those steps can involve outside processing and affect both price and lead time. When the RFQ leaves them unclear, the shop must ask for clarification or make assumptions. One quote might cover machining alone while another includes processing and documentation. A lower price may therefore reflect a narrower scope, and clarifying the requirements later can lead to a revised quote.

## Checklist: Quote-ready files and part data

Send the following inputs with your aerospace CNC machining RFQ. We use them to clarify part requirements before requesting manufacturer quotes.

- **Revision-controlled files.** Provide the current CAD model and engineering drawing, with their revision identifiers and applicable document-precedence requirements. Identify and resolve any conflicting geometry, dimensions, or notes before final quoting.
- **Order quantity and forecast.** Specify the quantity needed now and any expected repeat orders, with estimated volumes. A shop may price a one-time prototype differently from recurring production.
- **Material requirements.** Specify the alloy, applicable material specification, and required temper or condition, including any heat-treatment requirements and material certificates. If you leave the material condition open, the manufacturer may need to clarify availability before confirming price or lead time.
- **Tolerances and critical features.** Include all applicable dimensional and geometric tolerances, datums, drawing notes, and general tolerance requirements. Highlight critical features and any additional inspection requirements.
- **Delivery dates.** Give the required receipt date and any staged delivery quantities. Without those dates, a quoted lead time may not match your program schedule.

## Checklist: Quality and process scope to specify

Send the quality and process requirements with your aerospace CNC machining RFQ. The manufacturer needs them to price the work beyond machining, and we use them to check supplier fit through our [CNC machining service](https://vendra.io/cnc-machining).

- **Finishing and special processes.** Specify the required coating, plating, heat treatment, or other processing by drawing or contract specification. Identify masking, testing, and any approved processor requirements. A quote for machining alone will not cover these steps.
- **Inspection criteria.** Identify the features and tolerances that require inspection, along with required methods, sampling, and acceptance criteria. State whether you need a dimensional report and which characteristics it must include.
- **First article inspection.** If your contract requires an AS9102 first article inspection, state the applicable revision and the required report deliverables. Tell us when your program requires the report so we can include it in the quoted schedule.
- **Records and traceability.** List the documents the order must include, such as material certificates, special-process certificates, a certificate of conformity, and inspection reports. Specify any lot or serial-number traceability requirements so the manufacturer can plan how to retain those records.
- **Manufacturer credentials.** Specify any required manufacturing-site certifications, certificate scope, customer approvals, or approved-source restrictions. Vendra holds AS9100D certification and checks the selected manufacturer’s credentials against your order requirements.

## Handling controlled technical data in the RFQ

Before sharing controlled technical data with Vendra or a prospective manufacturer, confirm the intended recipients, access restrictions, and approved transfer method with your designated export-control team and Vendra.

Include any proposed finishing or inspection subcontractors among the recipients who may need access. Confirm applicable export controls, contract flow-down clauses, program-specific access rules, and supplier requirements before distributing the files.

Vendra is ITAR registered, but [registration does not grant export rights](https://www.ecfr.gov/current/title-22/chapter-I/subchapter-M/part-122/section-122.1). An approved upload method does not establish that every intended recipient may access the files. Your designated export-control team determines the restrictions on your data, and Vendra addresses the requirements for transfers it makes. Hold controlled files until both sides confirm the permitted recipients and method.

## Checklist: What an accurate quote should confirm

Compare the returned quote with your RFQ before placing an order. A price may change if the manufacturer has assumed a different drawing revision, omitted a required process, or excluded inspection records.

| Quote item | What to confirm | Why it matters |
|---|---|---|
| Drawing revision | The quote names the CAD and drawing revisions used for pricing. | A revision change can alter machining or inspection work. |
| Material | Alloy, temper or condition, stock form, and required material certificates match the RFQ. | A substitute material or missing certificate may not meet the order requirements. |
| Quantities | The quote identifies the quantity priced and any separate prototype or production pricing. | Setup costs and unit prices can change with volume. |
| Finishing and special processes | The quote includes specified coatings, heat treatment, and other outside processes. | Omitted work can add cost and lead time later. |
| Inspection and records | The quote lists inspection scope, any required AS9102 first article inspection, certificates, and traceability records. | You need to know which deliverables the order includes. |
| Setup and tooling | The quote identifies any setup or tooling charges and whether they are included in the total price or listed separately. | Check the full order cost, including one-time charges. |
| Exclusions and changes | The quote states assumptions, exceptions, and proposed substitutions. | You must approve departures from the RFQ before ordering. |
| Delivery schedule | Confirm the required receipt date, proposed shipment date or lead time, and what starts the lead-time clock, such as order acceptance, material availability, or drawing approval. | A shipment date may not meet the required receipt date, and the lead-time start affects the schedule. |

Resolve unclear items in writing and obtain an updated quote before you approve the order.

## How Vendra reviews and quotes aerospace CNC parts
