This system for designing gears is used for the most part to design or improve designs on new or existing gear sets.  However, there are additional capabilities of the system.

If provided with the proper information, virtual models of the gear teeth can be created to predict the proper location of the contact pattern. This information compared to the actual contact pattern can provide valuable insight to the cause of a failure or other problems. In addition, this approach can improve beam strength of the tooth up to 30% and significantly increase gear life.
