       abstract = "The use of automatic differentiation for an exact computation of geometric
         properties of bevel gear tooth flanks is discussed. Known models of the kinematics of the machine
         tools generating bevel gear tooth flanks have been improved. Using that result, we compute curvature
         properties of the generated envelope surfaces directly. From an analytical point of view, the
         envelope condition used in differential geometry can be interpreted as a singularity of a vector
         function in 3-space. By an analytical characterization of this singularity we obtain a
         two-dimensional parameterization of the generated flank for any machine parameter set. The necessary
         partial derivatives of the vector function are computed with the help of automatic differentiation.
         For the first time it is possible to compute the curvature properties and the resulting undercut
         geometry between tooth and fillet surface of the tooth flanks of any spiral bevel or hypoid gear
         without any approximation.",
