Gears are essential when driving motors and machines; they increase the output torque and adjust the direction and speed of rotation. They are primarily used to transmit rotary motion, but with suitable gears and flat-toothed components, they can convert reciprocating motion to rotary motion and vice versa.

　　Today's cars and trucks offer unprecedented levels of comfort and convenience, with great emphasis on reducing cabin noise to ensure the best possible driving environment. So the last thing an automaker wants to hear when testing its new car is the ubiquitous hum. But that's exactly what a major automaker found when testing vehicles rolling off an assembly line -- a mysterious hum that baffled their engineers. Using state-of-the-art non-contact surface metrology and optical technology, it was determined that the hum was caused by tiny ripples on the gear teeth of the rear differential, one of the vehicle's main drive components. The ripples are the result of the machining process and cannot be detected by traditional inspection techniques.

　　Once the root cause of the problem has been identified, gear manufacturers can improve their production process to eliminate noise, but still need a fast, quantitative and reliable way to continuously monitor the process to ensure the problem does not recur.
