Abstract: The effective control for the machining error is an important means for obtaining high precision and high efficiency of the unequal diameter profile machining of the arc surface cam. According to the space meshing principle and the rotation transformation tensor method, the contact line between the tool and the cam is analyzed; the cutter position offset and direction in the machining process are calculated. The actual working profile of the unequal diameter machining cam equation is established. Calculation method of normal error of globoid cam profile is deduced by the principle of differential geometry. The comparison between the machining error of the unequal diameter machining and the simulation experiment is carried out. The results verify the effectiveness of the new tool position control technique in error compensation.

Key words: arc surface cam, unequal diameter machining, error compensation, normal error, error control
