Manufacturing processes — turning, milling, drilling

What you'll learn

1. 1

   Imagine a block of clay spinning on a potter’s wheel. You press a tool against it to shape it — that’s turning!

2. 2

   In a lathe, the workpiece spins fast. The cutting tool moves left-right to shape it, like sculpting a spinning top.

3. 3

   What does turning do to the workpiece?

4. 4

   Now imagine a drill bit spinning and pressing into wood — that’s drilling. It makes a round hole.

5. 5

   You need a hole for a screw in a metal plate. Let’s watch how drilling works.

6. 6

   Milling is different — the cutting tool spins and moves sideways, like a cookie cutter carving shapes out of dough.

7. 7

   Which process is best for cutting a slot into a flat metal block?

8. 8

   A car axle is round and needs to be shaped from a metal rod. Which process would you use?
