摘要

A method for rounding by a rotating wheel sharp angles in teeth of a cutting tool rotating at the intersection gives the surfaces of revolution generated by their cutting edges characterized in that the tool axis inclined being with relative to a plane perpendicular to a main axis in a plane parallel to the axis of the grinding wheel in function of the angle of the faces of a tooth of the tool with a tangent to the surface of revolution generated by the edge plane angle cutting spending this main axis. the momentary center of curvature of the desired rounding two relative movements are caused enters the wheel and the tool one of which is a translational displacement which tends to bring them closer to one another and the other an oscillating movement around the main shaft the oscillating movement being synchronized with movement of the tool about its axis so that the wheel engenders a tooth of the tool a surface one by a tangent with at least existing tooth faces of the tool plane.
