Abstract: Aiming at the machining characteristic of personalized resin lens, on the basis of detailed analysis of the mathematical model of the lens, it puts forward the model of a 4-axis NC machining, used to replace the original surface processing to complete the task of 5-axis, based on the research and development of a new efficient automation personality resin lens processing equipment, the equipment has the manipulator up-down material dual axis high speed composite processing characteristics of the cutting tool instead of the grinding wheel grinding lenses processing technology, a clamping the outline of the lens cutting drilling surface engraving can be realized, and a series of complete composite processing, reduce the labor cost, greatly improving the machining precision and efficiency of the lens.
