Gear manufacturing is the process of creating gears, which are essential components in many machines. Gears transfer motion and torque between different parts, making them crucial in applications ranging from automobiles to industrial machinery. The manufacturing process often involves techniques like cutting, grinding, and hobbing to shape the gear teeth accurately. Quality control is vital in gear manufacturing to ensure that the gears function correctly and last long. Manufacturers often use CNC machines for precision and consistency. Additionally, materials like steel or plastic are selected based on the gear's intended use, balancing strength and weight for optimal performance.
