CNC & Laser Cutting
📋 What it is
CNC machines and laser cutters follow a digital design to cut or carve materials precisely — computer-controlled fabrication.
🗣️ Coach says
CNC machines and laser cutters are robots that cut EXACTLY to your digital design — a laser slicing wood or a spinning bit carving metal, guided by code. They make precise, repeatable parts no hand could match. Design it, machine cuts it.
🧠 Memory hook
CNC / laser = computer-guided cutting. Exact, repeatable, from a design.
😂 Giggle
Why was the materials scientist so stressed?
They were under a lot of pressure — and shear stress too!
😲 Whoa!
A laser cutter can cut a shape so precise and repeatable that it makes a hundred identical parts perfectly, one after another.
✅ Quick check: What is the advantage of using a CNC machine or laser cutter over cutting by hand?
Say your answer out loud first — then reveal.
They follow a digital design to cut precisely and repeatably — making exact, identical parts that would be very hard to cut by hand.
Computer-controlled precision is a key modern fabrication idea.

Imagine cutting 50 identical shapes — why would a machine beat doing it by hand?
