CNC Routing is a specific process within CNC machining (Computer Numerical Control Machining). It primarily involves using pre-programmed computer software to control a rotating cutting tool (such as an end mill or engraving bit) for precise cutting, engraving, milling, or shaping of materials. This technique is widely used for 2D or simple 3D planar processing, removing excess material from the surface to create detailed patterns, shapes, or structures.
Core Characteristics
Working Principle
Utilizes a rotating tool to cut materials layer by layer. It mainly operates along the X and Y axes (with limited Z-axis linkage for some machines), making it suitable for flat or slightly curved surfaces (distinct from complex multi-axis milling).
The tool’s movement and speed are controlled by numerical codes (G-code), ensuring high precision in each operation.
Suitable Materials
Primarily used for non-metallic or soft metallic materials, including:Wood (furniture panels, crafts), plastics (acrylic, PVC), foam (model making), composites (fiberglass, carbon fiber boards), and soft metals (aluminum, copper).
Less ideal for hard metals (e.g., steel), which are better suited for CNC milling or lathe processing.
Typical Applications
Advertising industry: Cutting acrylic signs, display boards, and lettering.
Woodworking & furniture: Engraving decorative patterns, cutting custom cabinet components, or shaping wooden parts.
Prototyping & modeling: Fabricating architectural models, industrial design prototypes (e.g., foam/plastic models).
Art & crafts: Creating relief carvings, personalized gifts, or decorative items.
Electronics & aerospace: Machining lightweight components (e.g., circuit board trays, composite parts).
Differences from CNC Milling
| ITEM | CNC Routing | CNC Milling |
| Material | Focuses on non-metals or soft metals. | Handles hard metals (steel, titanium) and rigid materials. |
| Axes | Mostly 2-axis (X/Y) or 2.5-axis (limited X/Y/Z linkage). | Typically 3-axis or multi-axis (4/5-axis) for complex 3D surfaces. |
| Tool Type | Uses small engraving bits or flat-end mills. | Employs larger milling cutters or drills for heavy-duty cutting. |
| Cutting Depth | Suitable for shallow or planar cuts. | Capable of deep cavities, through-holes, and intricate 3D structures. |

CNC Routing Advantages
High Precision & ConsistencyAchieves minimal error (usually within ±0.1mm) through program control, ideal for mass-producing identical parts.
Flexible CustomizationEasily adapts to design changes via CAD/CAM software (e.g., AutoCAD, VCarve) without physical mold adjustments, making it cost-effective for small-batch or custom projects.
Efficiency & Cost-EffectivenessReduces manual labor through automation and optimizes material usage, appealing to SMEs and creative industries.
Common Equipment & Software
Machines: Desktop CNC engravers, industrial CNC Router systems (often equipped with vacuum tables for material fixation).
