Ordering Process
How to Order Custom CNC Machined Parts
Use this CNC quotation-to-delivery workflow to see how a Formexi project works from controlled inputs. Provide the 3D model, 2D drawing, revision, quantity, material, finish, target date and inspection requirements; production starts only after missing information is resolved and scope, price and lead time receive written approval.
1. Submit Files and Requirements
Accepted project files may include STEP, STP, SLDPRT, IPT, PRT, SAT, X_T, IGES, IGS and STL, with PDF, DWG or DXF drawings. A 2D drawing is recommended for tolerances, threads, datums, roughness, appearance zones and inspection notes that should not be inferred from the model.
2. Engineering Review
Engineering reviews geometry, material, tool access, workholding, tolerances, finishing and inspection requirements. Review timing is confirmed after the files and commercial requirements are complete.
3. Formal Quotation
The quotation identifies part revision, quantity, material, process, finish, inspection requirements, unit price, non-recurring charges, production lead time, packaging, shipping terms, validity and exclusions. Questions are resolved before approval rather than hidden in production assumptions.
4. Order and Revision Approval
Production begins only after the commercial terms and controlling drawing revision are approved. Later changes receive a new revision and may change cost, scrap responsibility or delivery. Verbal design changes are not used as production authority.
5. Manufacturing and Process Control
Material preparation, programming, setup, first-piece checks, batch production and partner processes follow the approved routing. Progress updates may cover material, machining, finishing, inspection, packaging and shipment.
6. Inspection and Documents
Parts are inspected according to the agreed scope. Material certificates, full-dimensional reports, CMM, FAI, CoC and finish records must be requested before production because some evidence cannot be recreated after material is consumed or parts are shipped.
7. Packaging and Delivery
Parts are cleaned, separated where necessary, protected from corrosion or cosmetic damage and labeled to the order. DHL, FedEx, UPS, air or sea freight may be arranged only after the actual route, Incoterm, customs responsibility and charge are confirmed.
8. Delivery Follow-Up and Repeat Orders
For a quality concern, provide the order number, part number, revision, affected quantity, photos and measurement method. Confirmed manufacturing problems are reviewed for containment, rework, remanufacture, replacement, credit or another agreed resolution. Repeat orders are checked against the latest approved revision.
What the Engineering Review Confirms
The review converts the drawing and purchase requirements into a defined machining, inspection and approval scope before price or production is confirmed.
Formexi records open assumptions, required approvals and evidence requirements so the accepted quotation can become the controlled production baseline.
Prepare the RFQ for Review
Provide the controlling 2D drawing and 3D model, part number and revision, material condition, quantity, critical tolerances, GD&T, roughness, heat treatment, finish, inspection documents, packaging, destination and target date.
Price and lead time are confirmed after geometry, material availability, programming, workholding, external processes, inspection effort and logistics are reviewed together.
Check the complete RFQ inputs before submitting the project.
Prepare a Complete RFQ
Providing the model, drawing, material, quantity and inspection needs together reduces clarification time and prevents inaccurate quotations.
