Abstract: When plating CBN hard gear-honing processing with standard involute tooth
profile, generally there are a “mid concave” error near pitch circle of the work-piece tooth, and a
“dig root” error near its root. Since the factors of the error formation are complex, it is difficult to
calculate errors with an exact analytical method. Therefor, by the help of Pro/E and
ANSYS/LS-DYNA software, the analysis of plating CBN hard honing process is dynamically
simulated. Through picking up the datum from analysis results, the von mises stress distribution
values are listed along engaging points on the tooth surface. Due to the existence of relations
between the von mises stress and the tooth profile errors, the internal factors of the tooth profile
error formation of work-piece can be revealed, and the location and extent of the tooth profile
errors can also be discovered. It provides a theoretical basis for necessary modificatioin of the
gear-honing-tool tooth profile, and the results are consistent with the actual processing.
