Abstract

Computer Controlled Optical Surfacing (CCOS) is an important technology for manufacturing optical aspheric mirrors. Edge effect of small tool manufacturing restricts the machining precision and efficiency of CCOS technology. Edge effect is mainly caused by the polish tool cannot move to the very edge of workpiece and the change of pressure distribution when the tool move to the edge of workpiece. This article corrects the rolled edge effect of CCOS by different dimensions of polishing tool combination process and incorporated with the locality residual error trace contour path planning. Provide feasibility for the rolled edge by different dimensions of polishing tool combination process.
