ABSTRACT
The kinematics of gear machining processes with form cutting tools is simple. Only one motion is required for profiling of gear tooth flanks. This generating motion could be either a straight motion or a rotation. A combination of a translational motion with a rotational motion can also be implemented. In such a case, the translation and the rotation are timed with each other so as to comprise the screw motion. A screw motion, as well as particular types of screw motion (i.e., a translation and a rotation), represent a single parametric relative motion. Only single parametric motions are used for profiling of form tools for machining gears.
