  abstract = {<p>This paper presents a tri-dexel geometric engine integrated simulation model for the gear hobbing operation. The process kinematics are modeled and validated using CNC signals from a Liebherr LC500 hobbing machine. Workpiece geometry updating and cutter-workpiece engagement (CWE) calculations are efficiently realized in the tri-dexel engine. 3D force contributions at discretized nodes along the hob s cutting edges are computed considering the localized principal cutting directions, and rake and inclination angles. To measure cutting forces, a rotary&nbsp;dynamometer&nbsp;is successfully adapted and used alongside a&nbsp;Kalman filter&nbsp;to compensate for structural dynamics. The predicted forces agree well with their experimental counterparts.</p>
