Twist Control Grinding (TCG)


This paper introduces the latest process developments for the hard-finishing of gears in regards to controlling flank twist. Flank twist occurs as a matter of course when machining helical gears that feature lead modifications, and is brought about by the geometries and kinematics inherent in the continuous generating grinding of helical gears. Controlling the flank twist on gears, using twist control grinding (TCG), can either eliminate twist completely, or introduce a counter-twist to counteract the deformation of gears under load.
