WHAT WE REVIEW

What We Review in Your Drawings

We review the key features that affect machinability, cost, part quality, and production efficiency.
CNC machined part and caliper for tolerance review

Tolerances

Review tolerances to balance part function, machinability, and cost.
CNC machined bracket used for geometry and manufacturability review

Geometry

Review wall thickness, radii, undercuts, and other critical design features.
CNC cutting tool used to evaluate machining tool access

Tool Access

Check tool access and identify features that may be difficult to machine.
Threaded feature used for CNC hole and thread design review

Holes & Threads

Review hole sizes, thread specifications, depths, and machining access.
Machined metal samples used for CNC surface finish review

Surface Finish

Review surface finish requirements and suitable finishing processes.

OUR DFM REVIEW PROCESS

Our DFM Drawing Review Process

From drawing submission to engineering feedback and production planning.
01

Upload Drawings

Send your 2D drawings, 3D CAD files, and project requirements.
02

Engineering Review

We review manufacturability, tolerances, geometry, material, and key machining requirements.
03

DFM Feedback

04

Quotation & Next Steps

Confirm the final requirements, receive your quotation, and move forward with prototyping or production.
BEFORE VS. AFTER DFM REVIEW

Small Changes. Big Improvements.

Practical design adjustments can improve machinability, reduce unnecessary cost, and lower production risk.

Overly Tight Tolerances

Tighter than function requires, increasing manufacturing cost.
Use practical tolerances based on functional requirements.

Sharp Internal Corners

Sharp internal corners may require special tooling or additional machining.
Add a practical internal radius for easier and more efficient machining.

Deep & Narrow Features

Deep, narrow features can limit tool access and increase machining difficulty.
Improve tool access by adjusting depth, width, or feature geometry.

FAQ

Frequently Asked Questions

Common questions about our DFM and drawing review services for CNC machined parts.

We accept common 2D and 3D file formats, including STEP, STP, IGES, IGS, PDF, DWG, and DXF.

Yes. We can review 2D drawings, 3D CAD files, or both together to evaluate dimensions, tolerances, geometry, and overall manufacturability.

Please include material, quantity, tolerances, surface finish, and any critical functional or assembly requirements where applicable.

Yes. Where appropriate, we can suggest practical changes to improve tool access, tolerances, geometry, and overall manufacturability while considering the part’s functional requirements.

Yes. Once the design and project requirements are clear, we can provide a quotation for prototyping, low-volume, or ongoing production.

Review time depends on part complexity, drawing completeness, and project requirements. We will confirm the expected review time after receiving your files.
