What is CNC Routing? The Basics

Last month, a furniture designer came to me with a hand-drawn sketch of an elaborate headboard featuring intricate floral patterns. She’d spent weeks trying to find woodworkers who could carve it by hand—quotes ranged from $4,500 to $8,000, and timelines stretched 8-12 weeks. We used a CNC routing machine to produce it in 6 hours for $850. The precision was perfect, every detail crisp, and she could order more anytime at the same price. That’s the power of CNC routing.

The Simple Definition

Défonçage CNC is a computer-controlled cutting process where a spinning cutting tool (router bit) moves in three dimensions to cut, carve, and shape materials based on digital designs. CNC stands for “Computer Numerical Control”—essentially, a computer controls the machine’s movements with extreme precision.

Comment fonctionne le fraisage CNC

The basic process:

Step 1: Design Creation

• Create or import a digital design (CAD file)
• Define cutting paths, depths, and operations
• Generate toolpaths using CAM software
• Choose appropriate router bits and cutting parameters

Step 2: Material Setup

• Secure material to the CNC routing machine bed
• Use vacuum hold-down, clamps, or fixtures
• Set work zero (reference point for cutting)
• Verify material thickness and dimensions

Step 3: Machine Operation

• Load toolpath program into CNC controller
• Router spindle spins at high speed (8,000-24,000 RPM)
• Machine moves cutting tool through material on X, Y, and Z axes
• Material is removed layer by layer based on programmed paths

Step 4: Finishing

• Remove finished part from machine
• Clean up any remaining tabs or holding features
• Sand, finish, or paint as needed
• Quality check dimensions and details

Key characteristic: Unlike manual routing where a person guides the tool, a CNC routing machine follows programmed instructions with precision impossible for human hands to match.

Machine Components

Essential parts of a CNC routing machine:

Broche :

• High-speed motor holding the cutting tool
• Typical speeds: 18,000-24,000 RPM for wood, lower for metals
• Power: 1.5 HP (desktop) to 15+ HP (industrial)

Gantry and rails:

• Framework supporting the spindle
• Precision linear guides enabling smooth motion
• Belt-driven, rack-and-pinion, or ball screw systems

Control system:

• Computer brain directing all movements
• Reads G-code (machine instruction language)
• Controls spindle speed, feed rate, and tool position

Work bed:

• Surface where material is secured
• Vacuum hold-down, T-slot tracks, or sacrificial spoil board

Materials You Can Cut with CNC Routing

One of CNC routing’s biggest advantages is material versatility:

Wood and Wood Products

Most common CNC routing applications:

Solid wood:

• Hardwoods: Oak, maple, walnut, cherry
• Softwoods: Pine, cedar, poplar
• Applications: Furniture, cabinetry, decorative elements

Sheet goods:

• Plywood: All grades and thicknesses
• MDF: Medium-density fiberboard (very popular for routing)
• Particleboard: Budget-friendly option
• Baltic birch: High-quality plywood for precision work

Why wood dominates: CNC wood routing services are the most common because wood cuts cleanly, machines easily, and suits countless applications. A quality CNC routing company typically does 60-80% of their work in wood materials.

Real example: I work with a cabinet maker who produces 200+ custom kitchen cabinet doors monthly using CNC wood routing services. What once took two skilled craftsmen 3 days to produce, the Défonçage CNC machine completes in 4 hours with perfect consistency.

Plastiques

Common plastic materials:

• Acrylic (Plexiglass): Signs, displays, lighting
• Polycarbonate: Impact-resistant applications
• PVC: Outdoor signage, decorative elements
• HDPE: Cutting boards, marine applications
• Delrin: Engineering parts, tooling

Avantages : Plastics machine cleanly, come in many colors, and offer weather resistance for outdoor use.

Metals (Soft)

CNC routing machines can cut soft metals:

• Aluminum: Most common metal for CNC routing
• Brass: Decorative elements, architectural details
• Copper: Artistic pieces, electrical components

Limitation: Standard CNC routing machines handle only soft metals. Harder metals like steel require CNC milling machines with different capabilities.

Matériaux composites

Advanced materials:

• Carbon fiber sheets
• Fiberglass composites
• Foam core materials
• Corian and solid surface materials

Common CNC Routing Applications

Based on working with diverse clients seeking custom CNC routing solutions, these applications dominate:

Choosing a CNC Routing Service

If you’re not ready to invest in equipment, finding the right CNC routing company matters. Here’s what to evaluate:

Questions to Ask

About capabilities:

1. What’s your maximum material size?
2. What materials do you work with?
3. Can you handle 3D carving or just 2.5D cutting?
4. Do you offer design services or just cutting?
5. What file formats do you accept?

About quality:

1. Can you provide samples of similar work?
2. What tolerances can you hold?
3. Do you offer finishing services?
4. What’s your typical lead time?

About pricing:

1. How do you price jobs? (by time, square footage, complexity?)
2. Is there a minimum order?
3. Do you offer volume discounts?
4. What’s included in the price?

Finding Local Services

Searching for “CNC routing services near me” or “CNC wood routing services near me”:

Advantages of local providers:

• Easier communication and collaboration

• Good for simple, well-defined jobs

Getting Started with Your First CNC Routing Project

Ready to try CNC routing? Here’s practical advice from someone who has guided hundreds of first-time customers:

Project Selection

Start simple:

• Single-level cuts before attempting 3D carving
• Standard materials (MDF or plywood for wood routing)
• Reasonable size (within common sheet dimensions)
• Clear design without extreme detail

Good first projects:

• Simple wooden signs with cut-out letters
• Cabinet doors with basic panel designs
• Wall art with silhouette designs
• Name plates or address plaques
• Coasters or trivets

Design Preparation

File requirements:

• Vector files preferred (AI, DXF, SVG formats)
• CAD files work (SolidWorks, Fusion 360)
• High-resolution images can be converted (though less precise)
• Specify dimensions clearly

Design tips:

• Minimum feature size: 1/8″ for wood routing
• Corner radius: Router bits are round, so inside corners have radius
• Material thickness: Know this before designing
• Cutting depth: Specify how deep to cut

Working with Your CNC Routing Company

Communication is key:

• Explain intended use and requirements
• Discuss material options
• Ask about finishing recommendations
• Request timeline and pricing
• Clarify revision policies

Be realistic:

• CNC routing isn’t magic (physics and material limits apply)
• Intricate details cost more (time = money)
• Material choice affects results
• Some designs work better than others

Considérations sur les coûts

Understanding CNC routing pricing helps set realistic expectations:

Factors Affecting Cost

Machine time:

• Most CNC routing services charge primarily for machine time
• Complex cuts take longer than simple profiles
• 3D carving significantly slower than 2D cutting

Material cost:

• Material type and thickness
• Sheet utilization (how efficiently design fits)
• Waste material (some designs waste more)

Setup and programming:

• First-time designs require programming
• Simple cuts have minimal setup
• Complex 3D work requires more programming time

Finishing:

• Sanding, painting, or staining adds cost
• Edge finishing important for some applications
• Assembly if multiple components

Typical Pricing

Rough estimates (vary significantly by region and shop):

• Simple 2D cuts in wood: $1-$3 per minute of machine time
• Complex 3D carving: $2-$5 per minute
• Material markup: 30-100% over retail
• Setup fees: $50-$200 for first-time jobs
• Minimum charges: $50-$150 common

Example: A 24″×24″ wooden sign with basic text cutout might cost $85-$150 total (material, machine time, finishing).
