CCOS (Computer Controlled Optical Surfacing) is an important technology for off-axis aspheric surface processing. Edge effect of small tool manufacturing restricts the machining precision and efficiency of CCOS technology. After the key parameters of edge effect were obtained, the warping edge effect of CCOS combined with the residual error trace contour path planning was corrected. The full aperture optical measurement data of a stadium off-axis aspheric is achieved by processing, which provides the fundament for subsequent finishing.
