摘　　要：根据微分几何学,利用所建立的行星斜轧的坐标系及其变换矩阵,由轧辊锥面方程推导了轧辊与轧件两表面接触线上点的相对运动速度方程,借助所定义的碾轧方程,获得了轧件表面方程和接触线方程。By differential geometry, when several coordinates of planetary cross-mill are established and transform matrix are given, the relative motion equation that occurs in contact points on surfaces of mill rolls and stock is derived from an equation of conical mill rolls. With the help of the milling equation which has been defined, the equations of both stock surface and contact curve are obtained as well.
