1. High Volume Items
Many items you use every day are machined, and you probably have quite a few of each. Think the zippers on your coat and pants, the soles on your shoes, and even LEGO! Now, these things aren’t really machined in the way you might be thinking - LEGO produces millions of bricks, and machining each one really is not practical. Instead, each brick is created by an injection mold, which IS machined.
