Meshing Performance Analysis of a Topologically Modified and Formed Internal Helical Gear Pair
MachinesInternal helical gear pairs are sensitive to manufacturing and assembly errors, loading deformation, which can result in vibration and noise. Three-dimensional topological modification of tooth surfaces is available to reduce this sensitivity.

Study on Precision Grinding of Axisymmetrical Form. Mechanism of Form Generation.
Journal of the Japan Society for Precision Engineering, 1996 In grinding of axisymmetrical surfaces, residual removal increases in peripheral region. Therefore, the surface profile becomes concave and the form accuracy deteriorates. In this paper, the mechanism of generating axisymmetrical form error is made clear by analyzing the change of grinding force. The following facts are revealed by experiments.
