Hobbing is a machining process used to create gears, splines, and other toothed components. It involves a specialized cutting tool called a hob, which rotates and cuts the material to form the desired shape. The workpiece is fed into the hob, allowing for efficient and precise production of complex profiles. This method is commonly used in industries such as automotive and aerospace, where high precision and durability are essential. Hobbing can produce various gear types, including spur gears, helical gears, and worm gears, making it a versatile technique in manufacturing.
