Gear cutting is a manufacturing process used to create the teeth of gears, which are essential components in machines that transmit power and motion. This process can be performed using various methods, including hobbing, shaping, and milling, depending on the type of gear and its specifications. During gear cutting, a cutting tool removes material from a workpiece to form the desired tooth profile. The precision of this process is crucial, as it affects the gear's performance, efficiency, and lifespan. Properly cut gears ensure smooth operation in applications ranging from automobiles to industrial machinery.
