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 machined part.
A useful machining review starts with the drawing, the part function, and a clear view of what is critical. Pearson organizes those details before confirming a manufacturing path.
Project-specific routing
Material, quantity, timing, and feature access are considered before the process and fulfillment route are confirmed.
Quality intent up front
Critical faces, datums, tolerances, and documentation needs belong in the request so they can be reviewed before acceptance.
Fulfillment review
Requests are reviewed manually. The fulfillment route and availability are confirmed before acceptance.
Quote inputs
The information that starts a useful review.
You do not need every answer before submitting. Share what is known and mark the rest for follow-up.
- Request types
- Milling, turning, drilling, tapping, boring, reaming, deburring, finishing, and inspection requirements
- Helpful files
- STEP or STP model, PDF drawing, DXF, sketch, or clear photos of an existing part
- Material examples
- Aluminum, steel, stainless steel, brass, copper, and engineering plastics
- Project context
- Quantity, target timing, finish, mating features, part function, and inspection or documentation needs
Interactive part review
Explore the details that shape a machining review.
Select a feature on the sample housing to see what the drawing should communicate and why it matters during review.

Pocket depth, inside radii, and tool access
Deep pockets, narrow features, and small internal radii can influence tooling, setup planning, and machining time.
- Pocket depth
- Inside corner radii
- Wall and floor geometry
Helpful upload
Include the 3D model and call out any critical pocket dimensions on the drawing.
Illustrative part only. Geometry, equipment fit, tolerances, inspection, and documentation are confirmed from your files during quote review.
Capabilities
Common CNC request paths, kept easy to scan.
These examples help identify the likely starting point. Exact process fit and availability are confirmed from the project files.
Milled geometry
MillingPlates, brackets, housings, pockets, slots, fixtures, and prismatic parts with features across one or more faces.
Turned geometry
TurningShafts, bushings, pins, sleeves, spacers, rollers, and other components based around cylindrical geometry.
Holes, threads, and edge work
Secondary detailsDrilling, tapping, reaming, boring, countersinking, counterboring, chamfers, and deburring requirements.
Finish and inspection planning
CompletionSurface treatment, critical dimensions, documentation, and inspection expectations reviewed as part of the request.
Quote workflow
From files to a confirmed project path.
A short, human-managed review keeps assumptions visible before work is accepted.
- 01
Share the part
Upload the model, drawing, photos, quantity, material preference, and known requirements.
- 02
Review the details
Geometry, tool access, critical dimensions, finish, inspection, and documentation needs are reviewed.
- 03
Confirm the path
Process fit, fulfillment, timing, and open questions are resolved before acceptance.
- 04
Coordinate the project
Approved requirements become the reference point for production communication and delivery planning.
Drawing readiness
Small decisions that make review easier.
Clear intent is more useful than adding tight requirements everywhere.
Design intent before assumptions
- 01
Pair the model and drawing.
Use the model for geometry and the drawing for critical dimensions, threads, finishes, and notes.
- 02
Identify functional features.
Mark mating faces, fits, datums, and dimensions that affect how the part works.
- 03
Define holes completely.
Include diameter, depth, thread, fit, and access direction when those details are important.
- 04
Explain the application.
A short note about load, wear, environment, or mating components helps clarify design intent.
- 05
Include finish expectations.
Call out the required finish and which surfaces or cosmetic areas it applies to.
- 06
Flag what is still unknown.
Unknown material, timing, or inspection details can be discussed during follow-up instead of guessed.

FAQ
CNC machining quote questions.
A STEP or STP model and a PDF drawing are the best starting pair. Add quantity, material, critical dimensions, finish, inspection or documentation needs, and target timing when known.
Yes. Clear photos and key dimensions can start a replacement or repair discussion when CAD is unavailable. Additional measurements or a drawing may be needed before the project can be confirmed.
Identify the dimensions, fits, 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.
Prototype, replacement, repair, bridge, and repeat-production requests can be submitted for review. Process fit, quantity, timing, and fulfillment are confirmed per project.
Requests are reviewed manually. The fulfillment route and availability are confirmed before acceptance.
