FAQ

Frequently Asked Questions

What is CNC machining?

CNC (Computer Numerical Control) machining is a manufacturing process where pre-programmed computer software controls the movement of factory tools and machinery. It can control everything from lathes and mills to routers and grinders — allowing precise, repeatable cuts that would be impossible by hand. Learn more →

Can I learn CNC machining online for free?

Yes. CNC Dance offers 100% free tutorials covering G-code programming, CAM software, machine setup, feeds and speeds, and troubleshooting. Start with G-Code for Beginners or follow the 6-month learning roadmap — no signup required.

What is G-code?

G-code (Geometric Code) is the programming language that tells CNC machines where to move, how fast to cut, and what path to follow. Every CNC machinist needs to understand at least the basics. See the Complete G-Code List for a full reference.

What CNC machine should a beginner buy?

It depends on your budget and what materials you want to cut. For wood and soft materials, a desktop CNC router like the Shapeoko or Onefinity is a great start. For metal, you'll need a sturdier mill. Check our CNC Basics Guide for buying advice.

How long does it take to learn CNC machining?

You can write your first G-code program in a day, but becoming a confident machinist takes 6–12 months of consistent practice. Follow our CNC Learning Roadmap for a structured plan.
