A fixture for cutting gears mountable on a gear shaper comprising a housing formed with a longitudinal opening therein over which a gear cutting member slides in timed relationship to the shaper spindle on which the gear blank to be cut is carried for cutting engagement with said cutting member. The housing is secured to the gear shaper apron which is connected to the relieving mechanism to thereby obtain synchronization of movement between the reciprocating action of the spindle and the to-and-fro action of the housing on which the cutting member is carried. The cutting member is drivably connected to the gear shaper mandrel through the longitudinal opening by a cam and follower assembly. The cam and spindle are interconnected through the shaper gear box to establish a preselected ratio of rotation therebetween so that the cutting member slides linearly and tangentially in timed relationship to the rotation of the gear blank to be cut.
