{"data":{"fields":"term_definition","term_definition":"<div class=\"definition\">Represents a correction angle which is used to determine blade angle. Blades for cutting generated spiral bevel or hypoid gears are generally specified by the mean pressure angle of the gear to be cut plus a cutter number. For finishing blades, the correction in minutes equals ten times the cutter number divided by sixty minutes. The amount of the correction is added to the mean pressure angle to obtain the inside blade angle; it is subtracted from the mean pressure angle to obtain the outside blade angle.<\/div>"}}
