Capability boundary

Machine and inspection capability for CNC prototype RFQs

Use this guide to understand what DFocus can review before quoting: in-house CNC capacity, vetted partner routes, inspection equipment, dimensional evidence, tolerance limits, and when outside measurement may be needed.

Capacity is route-specific

3-axis, 4-axis, 5-axis, turning, mill-turn, sheet metal, casting, and 3D printing routes are confirmed after CAD, material, quantity, tolerance, finish, and deadline review.

Inspection is scoped by RFQ

Caliper, micrometer, height gauge, roughness, CMM, FAI, and dimensional reports are selected according to drawing callouts and agreed acceptance criteria.

Partner boundary is disclosed

If vetted partner capacity or outside measurement is needed, the route should be confirmed before production with confidentiality and documentation requirements agreed in writing.

Capability review table

What engineers confirm before production

Final capability depends on geometry, material, setup, feature access, finish, inspection method, and queue capacity. Critical dimensions should be marked on a 2D drawing.

Area
Typical review
RFQ evidence to provide
CNC milling3-axis, 4-axis, and 5-axis route fit, workholding, datum access, thin-wall risk, and surface reach.STEP/STP, 2D drawing, material, finish, tolerance class, marked critical dimensions.
Turning / mill-turnConcentricity, bore depth, thread callouts, OD/ID finishing, and secondary milling operations.Drawing with threads, fits, datum references, roughness, and inspection notes.
Inspection equipmentCaliper, micrometer, height gauge, pin gauge, roughness checks, CMM/FAI when required by drawing risk.Critical-to-function dimensions, sample size, report format, acceptance criteria.
Outside measurementSpecial CMM programs, third-party lab checks, material testing, or finish testing may require partner scheduling.Required standard, certificate format, due date, and whether buyer approval is needed before shipment.

Tolerance boundary

Do not quote critical tolerances from CAD alone

Critical tolerances must be marked on a 2D drawing. Final tolerance capability depends on geometry, material, setup, finish, feature access, and inspection method.

Lead-time boundary

Inspection scope can change the schedule

Simple machining may move faster, but CMM, FAI, special material certificates, cosmetic approval, outside testing, or partner routing can extend lead time.

Machine and inspection FAQ

Can DFocus guarantee a tolerance before reviewing drawings?

No. Standard and critical tolerances are confirmed after engineer review of geometry, material, setup, finish, feature access, and the required inspection method.

Which inspection documents should I request?

Start with marked critical dimensions. Ask for dimensional reports, CMM, FAI, material certificates, COC, finish photos, or packing proof only when they are needed for receiving inspection or approval.

Will all work be done in-house?

DFocus uses in-house manufacturing capacity and vetted partner routes when needed. If partner capacity or outside measurement matters for confidentiality or approval, state that requirement during RFQ.

Need capability checked against your drawing?

Upload CAD, 2D drawings, quantity, material, finish, tolerance notes, destination, and documentation needs. Complete RFQs are reviewed within 24 hours; complex DFM or multi-process quotes may take up to 48 hours.
