Friction drilling
Friction drilling is a way of making holes in materials like metals and plastics. It works a bit like rubbing your hands together really fast, which creates heat. When you do that, your hands get hot and you might even feel a tiny bit of smoke or see sparks. The same thing happens with friction drilling, but on a much bigger scale.
First, you need a special tool called a friction drill that spins really fast. You press the tool onto the material you want to drill and apply pressure. Then you start the drill and keep pressing down. The drill spins so fast that it creates a lot of heat and rubs away some of the material. As the material heats up, it becomes soft and gooey. The drill keeps spinning until it reaches the other side of the material, creating a hole.
The cool thing about friction drilling is that it doesn't create any chips or bits of material that could get in the way or damage the tool. Instead, the material that gets rubbed off forms a kind of "plug" that helps strengthen the hole. This makes friction drilling faster and more efficient than other methods, like traditional drilling or milling. It's also useful for making holes in materials that are really hard or difficult to work with, like hardened steel or carbon fiber.
So, think of friction drilling like rubbing your hands together really fast, only on a much bigger scale and with a special tool that makes a perfectly round hole.
