Cabinet making and CNC fabrication

Questions behind this page

Can plywood cabinets be made with a CNC machine? What knowledge and skills remain necessary?

CNC machining can produce repeated panels, joinery features, and hardware holes. A successful cabinet still needs a design, an assembly method, finishing, hardware, and accurate installation.

Work backward from hardware and use

Choose drawer slides, hinges, and other hardware before finalizing hole patterns and clearances. Define door arrangement, access, load, and finished dimensions. Then choose the panel and connection details.

Stage	Main task
Design	Establish layout, clearances, finished dimensions
Material specification	Select core, veneer, actual thickness, finish
CAD / CAM	Model joints, tolerances, tooling, hold-down, and cutting sequence
Test cut	Validate a joint and hardware pattern on the actual panel
Machining	Cut, drill, and label repeatable parts
Assembly	Confirm alignment, square boxes, and usable clearances
Finishing	Treat edges, surfaces, and visible defects
Installation	Level, secure, fit fillers, adjust doors and drawers

CNC does not eliminate fitting

Nominal thickness can differ from measured panel thickness. A dado based on the wrong value can make every repeated joint wrong. Tool geometry affects inside corners; joinery needs appropriate allowances rather than relying on a drawing alone.

Finishing and installation may dominate the work even when cutting is efficient. Veneer can be sanded through, edge banding requires careful application, and doors need consistent gaps.

Quality questions

Can hardware be adjusted and replaced? Will shelves and connections carry the intended use? Are moisture-prone edges protected? Is the finish compatible with maintenance? Make one representative module before committing to a complete kitchen.
