Acrylic CNC machining for functional geometry
CNC is the route for pockets, stepped faces, countersinks, controlled holes and thick-stock features that a flat 2D cutting path cannot produce. The drawing and approved paid sample set the inspection method.
Holes and mating features
Drilled, countersunk and counterbored holes and mating features located from the stated datums.
Fit-critical 2D dimensions: ±0.1 mm after review

Bases, fixtures and OEM components
Visible and functional edges finished to the approved sample; bonded parts, inserts, labels and protective packing.
Clear, colored and frosted cast PMMA

Choose CNC, laser or a mixed route
Use the drawing feature to select the process; a mixed route can assign each feature to the suitable machine.
| Drawing feature | CNC machining | Laser cutting |
|---|---|---|
| Pockets and steps | Primary route | Not a 3D pocketing process |
| Flat profiles | When stock or edge geometry needs machining | Efficient for compatible sheet |
| Countersinks and bores | Drawing-controlled toolpath | Needs a secondary operation |
| Visible edges | Machined or polished sample | Sample the process edge |
The quote states which route controls each feature. See the tolerance guide for critical dimensions.
Specify tolerance by feature
A useful CNC drawing separates functional dimensions from reference dimensions. State the datum, acceptable limit, material, visible surface, edge condition, revision and inspection method so the paid sample and production share one acceptance record.
- ±0.2 mmStandard working tolerance unless the approved drawing states otherwise.
- ±0.1 mmFit-critical 2D dimensions, after drawing review.
- Per featureMark only the dimensions that control fit or movement; we confirm the quoted capability and gauge before sampling.
A question we often get: “Does ±0.2 mm tolerance cover thickness, length and width?”
Drawing fields that change the quote
Material, datums, critical limits, machined features, appearance zones and released revision each affect machining or inspection.
| Material | Named PMMA grade, color and starting stock |
|---|---|
| Datums | Faces or features that control measurement |
| Critical limits | Only dimensions that control fit or movement |
| Machined features | Pockets, holes, threads, countersinks and edge breaks |
| Appearance zones | Visible faces, polish route and approved sample |
| Revision | One released drawing and artwork revision ID |

What sets the CNC part price?
We quote from the drawing and quantity tiers, because machine time and inspection vary with geometry.
- Starting stock and material grade
- Tool changes and workholding
- Critical dimensions and inspection
- Edge finish, packing and quantity
We run repeat production from a released drawing at 100+ pieces per design; we are not a one-off rapid-prototyping shop. See the prototype-to-production checklist.
Acrylic CNC Service FAQ
What is the MOQ for acrylic CNC machining service?
Production starts at 100 pieces per design. A different geometry, material, thickness or controlling drawing revision may count as a separate design. A paid pre-production sample is ordered separately before the production run.
How much does acrylic CNC machining cost?
The quote is driven by starting stock, machine time, tool changes, workholding, quantity, inspection scope, finish and packing. Send the drawing and the quantity tiers you are considering; we return an itemized production quote within 24 hours. We do not apply a generic per-part price to unmatched geometry.
What tolerance can Wetop hold on a CNC acrylic part?
Tolerance is reviewed dimension by dimension against the drawing, material, stock condition, geometry, datum plan and measurement method. Mark fit-critical dimensions and their acceptable limits. We confirm the quoted capability and inspection method before sampling instead of promising one tolerance for the entire part.
Which file formats should I send?
Send STEP for 3D geometry, DXF for controlled 2D profiles and a dimensioned PDF that identifies critical dimensions, material, finish and revision. The CAD and DXF preparation guide explains how the files work together.
Should my acrylic part be CNC-machined or laser-cut?
CNC is normally the better route for pockets, steps, countersinks, controlled holes, thick stock and functional edge geometry. Laser cutting is efficient for repeated 2D profiles in suitable sheet thicknesses. The CNC versus laser guide separates the two by geometry and finish.
Can I approve a prototype before production?
Yes. Paid samples normally take 3-5 days after the drawing, material and acceptance criteria are approved. Sample fees are paid separately and never credited. Production starts only after written sample approval and the agreed payment gate.
Can Wetop sign an NDA before I share drawings?
We can sign a reasonable NDA after reviewing and agreeing its terms. Your artwork and project files are used only to quote, sample and manufacture your order, never published or reused for another customer. The agreement should protect your confidential project information without treating common manufacturing methods as your exclusive property. Please send the proposed agreement for review before sharing confidential files.
Can you ship CNC acrylic parts DDP?
Yes. Ask for FOB Shenzhen and DDP as separate quote lines if you need to compare factory price with door-to-door landed scope. The final DDP line depends on the packed dimensions, weight, destination and current freight and duty treatment.
