How to Build Cabinets with a CNC Machine
If you’re passionate about traditional woodworking, you already understand the craftsmanship that goes into building quality cabinets. But with CNC technology, you can take that skill to the next level, combining your expertise with the speed, precision, and consistency that only a CNC machine can deliver.
Whether you’re crafting custom CNC kitchen cabinets for high-end remodels or pumping out bulk orders for contractors, a CNC machine gives you the power to build better cabinets faster. In this guide, we’ll cover everything you need to know about building cabinets with a CNC machine, from design and material selection to cutting, assembly, and finishing.
Why Use a CNC Machine for Cabinet Making?
Gone are the days of measuring twice and cutting once. With a CNC router, you measure once, program your design, and let the machine do the rest. The result? Perfect cuts, precise joinery, and flawless cabinet components in much less time than traditional methods.
The Benefits of CNC Cabinet Making:
- Unmatched Precision: No more human error or wasted materials. CNC machines cut exact dimensions with accuracy down to a fraction of a millimeter.
- Increased Efficiency: Cut, drill, and route complex cabinet components in a fraction of the time it would take manually.
- Consistent Quality: Every piece comes out identical, whether you’re making one custom cabinet or producing 100.
- Reduced Labor Costs: One machine operator can handle jobs that used to require an entire team of woodworkers.
Step 1: Design Your CNC Kitchen Cabinets
The first step in CNC cabinet making is designing your project in CAD (Computer-Aided Design) software. Popular programs for CNC cabinet making like Cabinet Pro, Mozaik, or KCD allow you to create precise cabinet layouts, complete with dados, rabbets, and pocket holes.
Key Design Elements to Consider:
- Cabinet face frame or frameless design
- Drawer box construction
- Hinge and hardware placement
- Material thickness and grain direction
Once your design is complete, the CAD file is converted into a CAM (Computer-Aided Manufacturing) file, which generates the toolpaths your CNC machine will follow.
Step 2: Choose the Right Wood
The material you choose is the foundation of quality CNC kitchen cabinets. The type of wood you choose will impact the look, durability, and machining process.
Best Woods for CNC Cabinet Making:
- Birch Plywood: Affordable and durable with a smooth surface for easy cutting.
- Maple: Popular for shaker-style cabinet doors and drawer fronts.
- MDF (Medium Density Fiberboard): Perfect for painted cabinets and custom door panels.
- Walnut or Oak: For high-end custom cabinetry with a rich, natural grain.
Step 3: CNC Machining the Cabinet Parts
With your design finalized and materials selected, it’s time to let the CNC router go to work.
Common Cabinet Parts Cut on a CNC Router:
- Cabinet sides and panels
- Face frames
- Drawer boxes
- Shelf pin holes
- Dado grooves
- Custom door profiles
Using nesting software, you can strategically position parts on each sheet of plywood to minimize waste and maximize efficiency.
Pro Tip:
Use a compression bit when cutting cabinet parts. This allows for clean, chip-free edges on both the top and bottom of the material — perfect for cabinet components that will be visible.
Step 4: Assembly and Finishing
Once your parts are cut, the assembly process is streamlined thanks to the precision of CNC cuts. Pieces fit together perfectly, and pre-drilled holes for pocket screws or dowels make for fast, error-free assembly.
Step 5: Sand, Finish, and Install
Once your cabinets are cut and assembled, it’s time to sand, stain, or paint them to match your project. CNC routers can even handle intricate details like custom door profiles and decorative carvings for a truly one-of-a-kind finish.

Boost Productivity with CNC Nesting
Nesting is a game-changer in CNC cabinet making. It allows you to lay out multiple cabinet parts on a single sheet of plywood, optimizing material usage and drastically reducing waste.
Benefits of CNC Nesting:
- Cuts production time in half
- Minimizes scrap and material costs
- Improves overall shop efficiency
In fact, with a ShopSabre CNC router, you can cut enough custom CNC kitchen cabinets for an entire kitchen in under an hour.
