Hobbing is a crucial gear-cutting process that involves the synchronized rotation of a hob and a workpiece, where the hob is progressively fed into the workpiece. This interaction resembles a worm (hob) and worm wheel (workpiece) running in mesh. Each hob tooth cuts its own profile, and the accumulation of all these cuts produces an involute profile in the workpiece. For single-thread or single-start hobs, one rotation of the hob results in one tooth being formed on the workpiece. Challenges in Metal Cutting Metal cutting is demanding, subjecting the tool and material to high forces, contact pressures, temperatures, and intense…
