There’s a debate in furniture making circles that’s been simmering for years and has recently boiled over: does using a CNC router make you a real furniture maker?

The traditionalists say no. Hand-cut dovetails are the mark of craftsmanship. If a machine does the joinery, you’re an operator, not a maker. The pragmatists counter that a CNC router is just another tool, no different fundamentally from a table saw or a thicknesser. Both replaced hand tool methods decades ago and nobody questions their place in the workshop.

I’ve been running a mid-range CNC router alongside traditional tools in our workshop for two years now. My take? Both sides are partly right, and both are missing the point.

What’s Actually Available for Small Workshops

The CNC landscape for small furniture workshops has changed dramatically. Ten years ago, a machine capable of furniture-quality work cost $50,000-$100,000 and required a dedicated operator with programming skills. Today, machines from Shapeoko, Onefinity, and Avid CNC offer genuine furniture-making capability for $5,000-$20,000.

These aren’t industrial production machines. They have smaller cutting areas (typically 600mm x 600mm to 1200mm x 1200mm), lower spindle power, and slower feed rates than their industrial counterparts. But for a small workshop producing bespoke pieces, they’re capable enough.

Our machine is an Avid CNC with a 1200mm x 1200mm bed and a 2.2kW spindle. It cost roughly $12,000 including the spindle, dust extraction attachment, and basic tooling. Installation and learning to use it effectively took about three months of evenings and weekends.

Where CNC Genuinely Helps

Repeatable Joinery

This is the biggest win. Cutting 24 identical mortises for a set of dining chairs by hand takes hours and inevitably produces slight variations. On the CNC, I program the joint once, verify the fit with a test piece, and then cut every subsequent joint to identical dimensions.

The consistency doesn’t just save time. It improves the furniture. Joints that fit precisely are stronger, look better, and assemble more predictably. Our chair production, which used to involve individually fitting every joint, now goes together cleanly from the machine.

Complex Curves and Shapes

Cutting consistent compound curves by hand requires exceptional skill and experience. The CNC handles complex geometry without effort, producing curves that are mathematically precise and repeatable.

We’ve taken on design work that we would have declined before getting the CNC. Table legs with tapered spiral profiles, curved drawer fronts, and shaped seat blanks for chairs are all jobs where the CNC’s precision and consistency make previously impractical designs achievable.

Template Making

Even when we cut joints or shapes by hand using a router and template, the CNC makes the templates. Previously, templates were hand-made from MDF, carefully shaped and smoothed, and gradually degraded with use. CNC-cut templates from high-density plastic or aluminium are precise and effectively permanent.

Prototyping

Testing a new design in cheap material before committing to expensive hardwood is much faster with a CNC. We can cut a full-scale prototype of a joint, a component, or even a complete small piece in MDF to check proportions, ergonomics, and assembly sequences before touching the real timber.

What CNC Doesn’t Do Well

Surface Quality

CNC-cut surfaces need finishing work. The tool marks left by a rotating bit aren’t the same as a planed or sanded surface. Every CNC-cut piece still needs hand finishing, whether that’s scraping, sanding, or planing. The machine gets you to 80% of a finished surface. The last 20% is still hand work.

One-Off Organic Work

For truly one-off pieces where the design emerges as you work, sculpting a live edge or following the grain to determine a shape, the CNC adds nothing. You can’t program spontaneity. The machine excels at predetermined geometry, not intuitive shaping.

Setup Time

For a single operation, hand work is often faster. Setting up a CNC cut involves designing the toolpath, setting work coordinates, selecting and installing the right bit, running a test, and then cutting. If you’re cutting one mortise, it’s faster to chop it by hand. The CNC wins on the second, fifth, and twentieth identical cut.

Large Components

Our 1200mm bed limits the size of individual components we can machine. Table tops, long shelves, and bed components don’t fit. We still process large pieces with traditional machines. Larger CNC machines exist but they need more workshop space and cost significantly more.

The Economics

Here’s an honest breakdown of whether the investment makes sense for a small workshop.

Machine cost: $12,000 (our mid-range setup) Tooling and accessories: $2,000 initially, about $500/year ongoing for bits and collets Software: $500/year for CAM software (Fusion 360 personal licence covers most needs) Learning curve: 3 months of reduced productivity while learning Workshop space: The machine takes up a 2m x 2m footprint including clearance

Against that investment, we estimate the CNC saves us roughly 15-20 hours per month on jobs we were already doing, plus enables us to take on projects we would have declined. At our hourly rate, the machine paid for itself in about 14 months.

The Craft Question

Does using a CNC machine diminish the craft? I don’t think so, any more than using a table saw diminished the craft when it replaced hand ripping. The skill shifts from executing cuts to designing them. The aesthetic judgment, material selection, finishing, and assembly are still entirely human decisions.

The best furniture I’ve made since getting the CNC is better than the best furniture I made before. Not because the machine is more skilled than my hands, but because it freed up time and mental energy that I now spend on design, finishing, and details that make the difference between good furniture and great furniture.

The machine doesn’t replace the maker. It replaces the tedious parts of making, and that’s exactly what tools are supposed to do.
