{"data":{"fields":"term_definition","term_definition":"<div class=\"definition\">A mathematical tool for studying tooth contact and the motion transmission of gear teeth. By use of an complexe computer software, TCA will accurately access the quality of bevel and hypoid gears operating under reasonable conditions before the teeth have been cut. In TCA, the gear and pinion tooth surfaces are mathematically described by cutter specifications and the settings of the machine used to cut the gears.<\/div>"}}
