Feature-led review
Pockets, profiles, slots, holes, threads, inside radii, and edge requirements are organized before the process path is confirmed.
CNC milling services
CNC milling, built around the features that matter.
Pockets, inside radii, hole patterns, datum faces, and edge requirements all shape the manufacturing plan. Share the model and drawing so Pearson can review what is functional and confirm the project path before acceptance.

Capability review
This page describes common request types. Available processes, equipment, tolerances, inspection, documentation, and fulfillment are confirmed for each quote.
Overview
A clearer way to plan a milled part.
A useful milling review starts with the part function, the geometry that drives cutter access, and a drawing that identifies the faces, holes, fits, and finishes that are actually critical.
Access and setup context
Part orientation, workholding surfaces, feature depth, and relationships across faces help reveal likely setup questions early.
Functional intent up front
Datums, mating faces, fits, finish areas, and inspection expectations belong in the request instead of being inferred later.
Fulfillment review
Requests are reviewed manually. The fulfillment route and availability are confirmed before acceptance.
Quote inputs

- Helpful files
- STEP or STP model, PDF drawing, DXF when relevant, sketch, or clear photos of an existing part
- Features to identify
- Pocket depth, inside radii, hole and thread details, datum faces, edge breaks, and surface requirements
- Project context
- Material preference, quantity, target timing, finish, part function, and inspection or documentation needs

Pocket depth, inside radii, and cutter access
Pocket depth, wall geometry, and the smallest inside radius influence tool selection, reach, and the likely cutting approach.
- Pocket depth and floor geometry
- Smallest inside corner radius
- Wall access and required finish
Helpful upload
Use the 3D model for geometry and mark critical pocket dimensions, radii, and floor requirements on the drawing.
Illustrative part only. Geometry, equipment fit, tolerances, inspection, and documentation are confirmed from your files during quote review.
Capabilities
Common CNC milling request patterns, kept easy to scan.
These examples help identify the likely starting point. Exact equipment fit, achievable tolerances, and availability are confirmed from the project files.
Prismatic geometry
Pockets & profilesPlates, brackets, housings, covers, adapters, pockets, slots, profiles, and fixture components with features on flat or stepped faces.
Patterns, counterbores, and threads
Hole detailsClearance holes, dowel locations, counterbores, countersinks, tapped features, and hole patterns defined by function.
Features across multiple faces
Setup planningGeometry that crosses faces or depends on a shared datum may require additional orientation, access, and inspection review.
Finish and inspection requirements
CompletionEdge condition, surface treatment, critical dimensions, documentation, and inspection intent reviewed with the part request.
Quote workflow
From files to a confirmed milling path.
A short, human-managed review keeps geometry and open questions visible before work is accepted.
- 01
Share the part
Upload the model, drawing, photos, quantity, material preference, and known functional requirements.
- 02
Review the features
Pockets, radii, access, hole details, datums, finish, and inspection intent are organized for follow-up.
- 03
Confirm the path
Equipment fit, tolerances, fulfillment, timing, and remaining questions are resolved before acceptance.
- 04
Coordinate the project
Approved drawings and requirements become the reference point for production communication and delivery planning.
Drawing readiness
Small decisions that make a milled part easier to review.
Clear functional intent is more useful than applying tight requirements everywhere.
Design intent before assumptions
- 01
Use the largest practical inside radius.
Round milling cutters leave an internal radius. More generous corners can improve access and reduce reliance on smaller tools.
- 02
Avoid deep, narrow pockets where possible.
Depth relative to width can affect cutter reach, rigidity, chip removal, and the number of passes needed.
- 03
Tighten only functional features.
Apply close requirements to the fits, faces, bores, and locations that affect how the part works.
- 04
Define holes and threads completely.
Include diameter, depth, counterbore, thread, fit, and pattern intent where those details matter.
- 05
Identify the datum relationships.
Show how mating faces and features across setups relate instead of leaving the inspection origin unclear.
- 06
State the edge and finish intent.
Separate functional, cosmetic, deburred, chamfered, and surface-treated areas on the drawing.

FAQ
CNC milling quote questions.
A STEP or STP model and a PDF drawing are the best starting pair. Add quantity, material preference, pocket and hole details, datum intent, finish, inspection or documentation needs, and target timing when known.
Plates, brackets, housings, fixture plates, covers, adapters, blocks, pockets, slots, profiles, hole patterns, and features across multiple faces can be submitted for review.
Show the pocket geometry in the model and identify critical depth, floor, wall, and inside-radius requirements on the drawing. Round cutters leave an internal radius, so the smallest functional corner should be clear.
Identify the dimensions, fits, faces, and relationships that affect function. Achievable tolerances and the required inspection approach are confirmed from the drawing during quote review.
Include the required finish, affected surfaces, critical dimensions, and documentation expectations in the request. Scope and availability are confirmed before acceptance.
Requests are reviewed manually. The fulfillment route and availability are confirmed before acceptance.
