Advertising & signage
Acrylic cutting and 3D letter / character production for logos, light-box panels, and display graphics.
Large-format CNC routing for sheet goods and soft materials — cutting, engraving, drilling, and shaping at speed.
CNC Routing Services use computer numerical control (CNC) routers with high-speed rotating bits to cut, engrave, drill, and shape materials. As a subtractive process, routing is especially strong on large-format panels and soft materials, and is a core method for woodworking, advertising signage, and furniture manufacturing.
CNC routing is a computer-controlled subtractive process. A rotating router bit moves in X, Y, and Z according to a programmed path, cutting material fixed on the table into the required shape, pattern, or text. CAD designs are converted to G-code through CAM software, which then drives the machine.
Best fit: large sheet work and soft materials where “large and fast” beats “small and ultra-precise.”
This is key to understanding CNC routing — both are CNC subtractive processes, but they focus on different jobs:
| Comparison | CNC Routing | CNC Milling |
|---|---|---|
| Applicable materials | Primarily soft materials: wood, plastics, foam, aluminum, brass | Soft and hard metals: steel, titanium, stainless, and more |
| Machine structure | Gantry-style; lighter rigidity | Heavy-duty frame; high rigidity |
| Spindle traits | High speed, lower torque | Lower speed, high torque |
| Work format | Large-format sheets; large table area | Typically block-shaped workpieces |
| Accuracy level | Medium precision (around ±0.025 mm class) | Micron-level high precision |
| Typical applications | Furniture, signage, decorative panels, packaging molds | Precision molds, aerospace parts, medical devices |
Simply put: routers excel at “large and fast” sheet work; mills excel at “small and precise” hard-metal parts.
AIHFABS CNC routing is especially strong in these application areas:
Acrylic cutting and 3D letter / character production for logos, light-box panels, and display graphics.
MDF and solid-wood panel carving for cabinet doors, decorative panels, and custom furniture components.
Aluminum and plastic shell milling for device housings, panels, and lightweight covers.
Circuit-board engraving and drilling for rapid PCB prototypes and isolation routing.
| Type | Characteristics | Typical Uses |
|---|---|---|
| Desktop router | Small footprint, low cost | DIY projects, small parts, education |
| Industrial router | High power, large format, higher rigidity | Batch furniture and advertising signage |
| Multi-axis (3/4/5) | Multi-axis motion for complex 3D shapes | Sculptures, complex contoured molds |
| ATC (auto tool change) | Automatic tool changes between operations | Multi-step complex parts with less manual work |
| Nesting-optimized | Intelligent nesting for material yield | Cabinet doors and batch furniture panels |
| Operation | Description |
|---|---|
| Profiling | Cut and form along the outer contour of the part |
| Pocketing | Mill grooves or cavities inside the material |
| Drilling | Through-holes or blind holes |
| Slotting | T-slots, cable channels, and similar grooves |
| V-grooving | V-bit engraving for text and decorative lines |
| Surface engraving | Shallow engraving of text, logos, and patterns |
| 3D carving | 3D reliefs and sculptural forms |
| Chamfering | Edge chamfers and bevels |
CNC routers are not suitable for high-hardness materials such as hardened steel or titanium alloys — choose CNC milling for those parts.
Table area far larger than typical mills — ideal for full-sheet cutting
Lower equipment and process cost than milling on soft materials
High-speed spindles with ATC deliver high throughput
AI nesting can reach about 94%–97% sheet utilization
The same design can be replicated accurately in batch
Excellent for intricate decorative patterns and 3D reliefs
| Industry | Typical Applications |
|---|---|
| Woodworking & furniture | Cabinet doors, table/chair parts, decorative panels, carving |
| Advertising & signage | 3D letters, LED light-box bases, acrylic logos, display racks |
| Construction & décor | Decorative wall panels, door carving, railing balusters |
| Automotive / aerospace | Instrument panels, interior trim, carbon-fiber parts, battery housings |
| Mold making | Thermoforming molds, casting molds, packaging molds |
| Electronics | PCB prototypes, equipment housings, ceramic substrates |
| Medical devices | MRI enclosures, surgical guides, equipment panels |
Routing cost is mainly driven by:
Wood is usually cheapest; carbon fiber and aluminum cost more
3D reliefs cost more than simple 2D cutting
Tighter accuracy increases machining time
Larger batches lower unit cost
Finishes and paint add extra cost
5-axis costs more than 3-axis; ATC raises efficiency and machine cost
