Revolution (lathe)

You've definitely seen a picture of a tornado — or even a tornado itself — and can vividly imagine the whirlwind revolving around an invisible axis. That's how the revolution aka lathe works — rotates the object around a given axis and gets a symmetrical output shape. For example, by rotating an edge, you'll get a face, and by rotating the face, you'll come up with a solid shape.^[1]

The lathe operation took its name from a real machine tool that rotates a workpiece to create a symmetrical item. Lathes are widely used in woodturning, metalworking, metal spinning, thermal spraying, parts reclamation, and glass-working. The best-known appliance of a lathe tool is a potter's wheel for crafting ceramics.
