Gear hobbing is a machining process that uses a specialized cutting tool called a hob to generate gear teeth. The hob and gear blank rotate in a synchronized motion while the hob feeds across the blank's face, cutting precise teeth. This continuous process is highly efficient for producing spur and helical gears with excellent accuracy and surface finish.
