MachForge — CNC Manufacturing
Coordination &
Engineering Support

Engineering-led CNC manufacturing coordination for robotics, UAV and hardware teams.

From DFM review to prototype and low-volume production, I match each job with suitable manufacturing capacity based on the part's process, material, tolerance and finish requirements.

What This Is

An engineering coordination
layer for CNC manufacturing
and manufacturability decisions.

This is not a factory. I connect design teams with manufacturing suppliers in China.

I work directly with clients to review manufacturability, identify production risks, and recommend practical manufacturing approaches before production begins.

Why not just contact a CNC factory directly?

Most machine shops focus on making parts after a quote is approved. My role starts earlier, while the design can still change.

How to Work Together

Not a platform.
A conversation.

01

You send CAD or project information

File, drawing, or a description of what you're making — by email or LinkedIn. No form, no account.

02

I review manufacturability

I go through the geometry, tolerances, and process fit. Real engineering review, not an automated check.

03

I provide feedback and recommendations

You receive written DFM feedback: risks, recommended approach, and cost range where applicable. No commitment needed.

04

I coordinate manufacturing if needed

If you want to proceed, I route production to the right supplier and inspect parts before they ship.

Engineering Case Studies

Real DFM decisions
made before production.

Case 01

316L Stainless Steel Component
DFM Review

Identified an O-ring groove tolerance that would over-compress the seal at assembly. Groove depth, sealing-face finish, and thread-interface tolerances — held to roughly ±0.02–0.03 mm — were reviewed across several rounds before the first prototype was cut.

Case 02

Robotics Component
CNC Process Optimization

Reviewed a robotics housing's mechanical geometry in 6061 aluminum and worked out a fixture strategy to control thin-wall deformation, along with machining sequence and tolerance allocation — including a mounting-hole position tolerance held to ±0.01 mm. Focus: reducing machining difficulty without loosening the tolerances the part's function depends on.

Case 03

UAV Hardware
Prototype to Low-Volume Production

Coordinated CNC machining of 7075 aluminum components, red anodizing, and CMM inspection for a UAV hardware program moving from prototype into a 100-unit low-volume production run, with parts tracked through to shipment.

See the FAQ below for full conditions.

Q1

What is your typical lead time?

+

Typical prototype lead time is 3–7 business days after the drawing, material, process, and inspection requirements are confirmed. Low-volume production is typically 10–15 business days, depending on quantity, complexity, finishing, and inspection scope.

Q2

What machining tolerances can you support?

+

Standard CNC features can often be produced around ±0.05 mm, depending on geometry and material. Tolerances down to ±0.01 mm may be achievable on selected features after process review, with appropriate equipment and inspection. These values are not blanket tolerances for every dimension.

Q3

What is your minimum order quantity?

+

MOQ is typically 1 piece. I support engineering prototypes, DFM validation builds, and small-batch production without strict volume requirements.

Q4

Can you work under an NDA?

+

Yes. I can work under a standard NDA or review a customer's NDA before handling confidential engineering information.

Q5

Is shipping included in the production lead time?

+

No. Production and shipping times are quoted separately. The shipping method, destination and import responsibilities are confirmed before the order is approved.

Get in Touch

The fastest way
is the direct way.

Send your CAD file or drawing. I'll review manufacturability and provide feedback.

Typical response time: 24–48 hours depending on project complexity.
