New principle of processing optical aspherical components with locus compensation method

摘要：

　　A new principle of processing asphere with locus compensation method has been presented.The mathematical model for principle of machining aspherical surface with locus compensation method was created based on the equidistant line formula.The feasibility and practicability was analyzed and the corresponding processing program was made by MATLAB and Visual basic.The overall structure of corresponding machine tools was designed.The program can figure out the compensation error of quadratic curves and the designed machine tools can perform the functions of interception and compensation of quadratic curves,which meets the basic motion requirements of ultra-precision machining.All quadric and high order aspherical surface will be achieved and the surface form accuracy also will be improved.The structure of machine tools is simple and processing range is wide which will reduce the cost of machining greatly.
