Gear geometric control software : approach by entities

Formany years the transmission industry has had a major impact on the design of mechanical parts. In addition to geometric quality of the forging process, netshaped bevel gears ofer new ways to decrease cots and to increase mechanical properties. This paper deals with the dificulty in applying classical quality inspection to forged bevel gears. We developed a new approach based on entities and used it in an industrial context. One aspect of this method is that the gear teeth can be measured regardless of assembly surfaces. KeywordsBevel gear.Geometric control. Precision manufacturing.Process capability. Integrated design
