CNC 101
Your first machine.
Your first projects.
CNC means computer numerical control: a computer guides a cutting tool along a plan you prepare. Learn what to buy, how the pieces work together and how to turn a simple drawing into your first useful projects.
Reading time excludes practice. Move at your own pace.
Your learning, at your pace
Read any lesson at any time. Reviews track learning, not permission to operate a machine. Notes and review progress are optional.
What you are working toward
Choose a suitable setup, prepare a checked cutting plan, and work toward a recessed name plaque and shallow tray with appropriate instruction.
What you need to start
Begin with a project idea, paper and access to design software. You can complete the buying and design lessons before owning a machine. Operating practice needs the exact manuals and hands-on instruction.
Your learning route
Stage 1
Understand the machine and your budget
3 min reading, plus practice
What is CNC, and what can you make?

Stage 3
Make something useful and keep the lesson
3 min reading, plus practice
Learn without sacrificing expensive material
Use simulation, known offcuts and small representative tests to learn efficiently.
Open lesson →3 min reading, plus practice
First CNC project: a recessed name plaque
Make a simple shallow design on a larger blank, keeping the outside firmly held.
Open lesson →3 min reading, plus practice
Next CNC project: a shallow catch-all tray
Reuse a simple tool and setup to make a useful tray, then inspect what changed.
Open lesson →3 min reading, plus practice
Keep the good results and know when to stop
Troubleshoot thoughtfully, maintain the machine and upgrade based on evidence.
