斜齿轮成形磨削加工时，根据当量齿数直齿轮修整成形砂轮精度不易保证。
When a nelial gear is under form grinding, it is not easy for form grinding wheel, if dressed by the equivalent number of teeth of spur gear, to attain the precision required by standards.
利用UG软件的相关功能，生成直齿圆锥齿轮的当量齿轮的齿廓曲线，并沿分度圆锥母线扫描获得齿廓曲面片体；
By using the related method of UG, the profiles of virtual gear are generated, the profile surface is formed by swept along the generater of graduation cone;
