A Study On New Technology Of Rocessing Aspheric Optical Parts By Locus Compensation Method

This paper presents a new processing method-locus compensating method after analyzing the present processing situations of aspheric parts . using the formula of equidistant line, we create the mathematical model of working principle of the locus compensating method , demonstrate the correctness, feasibility and practicability of the method and made corresponding processing program with MATLAB and VB . at last, we devise the corresponding general structure of machining tools on the basis of above .The program we made can calculate all kinds of compensating errors of quadric curve whose calculation accuracy can reach 10-6mm . the machining tools we devised can perform the functions of interception of quadric curves and errors compensation ,which meets the demand of basic movements . When the machining tools is perfected , it can process all of quadric curves and high degree curves with high surface form precision . At the same time , the its structure is very simple processing size range is large and its efficiency is high , so it will greatly reduce the cost of processing of aspheric parts .
