## How It Works

CNC (Computer Numerical Control) routing is a subtractive machining process that uses rotating cutting tools to shape materials along a programmed path. Unlike CNC milling, which operates on three axes and handles harder metals, CNC routing specializes in softer materials and achieves excellent edge quality on wood, plastic, composite, and foam. Our process begins with your digital design file (DXF, DWG, or PDF). We convert your design into machine code, run feasibility checks, and set up your material on our routing bed. The cutting tool then follows the programmed path with precision, removing material to create your custom shape. Typical turnaround: 3–5 business days for standard jobs; rush options available. For CNC cabinet manufacturing specifically -- door styles, box construction, sheet nesting, and hardware integration -- see [CNC Routing for Cabinets](/capabilities/cnc-routing-cabinets).

## Precision and Specifications

What you can expect from our routing process.

- **Standard tolerance:** ±0.03 in. (up to 24 in. dimensions)
- **Tight tolerance (extra):** ±0.01 to ±0.02 in. on critical features
- **Surface finish:** Standard tool marks; sanded or mirror finishes available
- **Min feature size:** 0.125 in. interior corners and tight radii
- **File formats:** DXF, DWG, PDF (vector), AI, CorelDRAW
- **Edge quality:** Clean on most materials; minor cross-grain chipping on wood
- **Color & finish:** Routing is mechanical; staining/painting/edge-banding are secondary operations

**Design for manufacturability:** Avoid extremely long, thin walls (prone to vibration); keep inside corners at minimum 0.125-inch radius; specify material thickness clearly. Acrylic may show white stress marks on internal cuts.

## Cost and Pricing

CNC routing cost is driven by several factors. The ranges below are illustrative -- your actual quote depends on your specific project.

**What affects cost:**

- **Material cost:** Wood is typically $15–$80 per sheet (walnut higher than pine). Plastic and composites $20–$150+. Aluminum $40–$200+.
- **Setup & tooling:** A one-time programming and setup fee ($50–$150) applies per unique design. Repeat orders reuse the same setup.
- **Run quantity:** Single parts cost more per unit than production runs. Batches of 5–50 units reduce unit cost by 20–40% vs. one-offs.
- **Complexity:** Simple rectangular cuts cost less. Intricate detail, tight tolerances, and secondary operations increase price.
- **Turnaround:** Standard 3–5 business day turnaround is included. Rush orders (24–48 hour) incur a 15–25% premium.

**Typical price ranges:**

- Individual component: $25–$150
- Door panel: $40–$300
- Custom signage: $100–$500+

## Frequently Asked Questions

### What is CNC routing and how does it differ from other cutting methods?

CNC routing is a computer-controlled subtractive process where a spinning bit removes material from a flat sheet or block. Unlike laser cutting, routing works on thick, dense materials and leaves a clean machined edge. Unlike waterjet, it requires no drying time and leaves no heat-affected zone. CNC routing excels on wood, plastics, composites, and aluminum sheets up to 4 inches thick, making it the preferred method for structural components, dimensional parts, and anything requiring a routed profile or pocket.

### What tolerances can you hold on CNC routed parts?

OpenSpindle holds tolerances as tight as +/-0.01 inches on standard CNC routed parts. For most wood and sheet goods, we target +/-0.015 inches across the full part. Tolerances on plastics like HDPE and acrylic are typically tighter due to lower material movement. If your design requires tolerances under +/-0.01 inches, share your specs when requesting a quote at openspindle.com/quote and we will confirm feasibility and any additional setup requirements before production begins.

### What materials can you CNC route?

We route hardwood and softwood lumber, MDF, plywood, MDO, HDPE, UHMW, acrylic, polycarbonate, PVC foam board, Corian and solid surface, fiberglass composite panels, and aluminum sheet up to 0.25 inches thick. Material availability can vary, so if you have a specific grade or specification such as marine-grade plywood or flame-retardant ABS, include it in your quote request at openspindle.com/quote and we will confirm stock or sourcing options.

### What file formats do you accept for CNC routing?

We accept DXF, DWG, SVG, and AI vector files for 2D profiles and cuts. For 3D machining and relief work, we accept STL, OBJ, and STEP files. Fusion 360, Rhino, and SolidWorks exports are all compatible. Files should be drawn at 1:1 scale with cut lines, score lines, and drill locations on separate layers. If you only have a PDF or raster image, our team can redraw the geometry for a small setup fee. Submit your project at openspindle.com/quote or contact us before submitting.

### How much does CNC routing cost per piece or per sheet?

CNC routing pricing depends on material, part complexity, cut time, and quantity. Simple parts from a 4x8 sheet of MDF or plywood typically start around $25-$60 per sheet for cutting time alone, not including material. Complex parts with interior pockets, multiple tool passes, or tight tolerances cost more. Per-piece pricing drops significantly at quantities of 10 or more. There are no minimum order requirements at OpenSpindle. Submit your project at openspindle.com/quote with your DXF or DWG file for an accurate line-item estimate.

### How long does CNC routing take from file to finished part?

Standard turnaround is 3-5 business days from approved file to completed parts. This covers file review, CAD/CAM programming, Cutting, and quality inspection. Rush orders can often be completed in 1-2 business days for an additional fee, subject to schedule availability. Complex 3D machining jobs or large production runs may require 7-10 business days. Lead times are confirmed at the time of quoting, so you always know your timeline before committing. Submit your project at openspindle.com/quote to get started.

### Is there a minimum order quantity for CNC routing?

No, OpenSpindle has no minimum order quantity. We cut single prototypes and one-off custom parts as readily as we handle mid-volume production runs. For single pieces, expect a one-time setup fee that covers file review and CAD/CAM programming. That fee is reduced or waived on repeat orders of the same part. If you need a prototype first and then a production run, just let us know at openspindle.com/quote and we will hold your toolpath on file for fast reorders.

### Do you offer finishing services after CNC routing?

Yes. We offer Edgebanding on plywood and MDF panels, Sanding to 120 or 220 grit, and priming for paint-ready surfaces. We do not offer painting, staining, or coating in-house, but Finished and sanded parts are ready for your Finishing process immediately on receipt. Edgebanding is available in PVC and wood veneer tape in standard widths. Request finishing options when submitting your project at openspindle.com/quote so they can be built into your lead time and pricing.

### Can you CNC route aluminum?

Yes, we route aluminum sheet and plate up to 0.25 inches thick, including 6061-T6, 5052, and 3003 alloys. Aluminum routing requires slower feed rates and carbide tooling, which is reflected in pricing. Expect roughly 2-3x the cutting time compared to equivalent cuts in MDF or plywood. Tolerances of +/-0.015 inches are standard for aluminum sheet work. For aluminum extrusions, thicker plate, or structural profiles, submit your project at openspindle.com/quote or contact us to discuss feasibility before submitting files.
