Abstract

A method for controlling a process for manufacturing a bevel gear includes forming, via a first process, a ring gear and determining a first set of parameters associated with the ring gear, and forming, via a second process, the pinion gear, and determining a second set of parameters associated with the pinion gear. The ring gear and the pinion gear are paired, and a single-flank test is executed on the paired ring gear and pinion gear to determine a third set of parameters. The paired ring gear and pinion gear are assembled into a final assembly, and an end-of-line noise/vibration analysis of the final assembly is executed. The noise/vibration analysis, the first set of parameters, the second set of parameters, and the third set of parameters are evaluated, and one of the first process, the second process, the pairing process, and the assembly process are adjusted based thereon.
