Boring in manufacturing is when you make a hole in something like metal or wood. Imagine you have a block of cake that you want to put a straw through. You need to make a hole in the cake so the straw can go through. That's what it's like when you bore in manufacturing. Instead of using a straw, you use a tool called a drill bit that spins really fast and cuts the material to make the hole. Boring can be important because sometimes you need to make really precise holes for things like machines or engines to work correctly.
