Using plated CBN hard honing wheels with standard involute tooth profiles, there will be the middle concave error around pitch circle on the machined gear tooth surfaces. Therefore, standard involute tooth profiles of honing wheels have to be modified properly before electroplating CBN. In the paper, aiming at the tooth profile modification of honing wheels, the standard involute curve was converted into a spline curve, and control points of the spline curve were parameterized in solid modeling of honing wheels. By the Pro/E and ANSYS Workbench software, the engaging situation between honing wheel and gear was analyzed. Based on the analysis results, assuming the control points around pitch circle were set as variable parameter, and basically equal contact pressures were set as response variable parameter, the tooth surfaces of hard honing wheels were properly corrected, it was proved useful to reduce or eliminate middle concave error in practice.
