Method for measuring profile of large aspheric optics at grinding stage based on NC machine

Yichun Zhang, Fan Bin, Jia Bin Zhou

Abstract

According to the measurement at grinding stage, we put forward a method based on numerical control machine tools(NC) to measure profile of large aspheric optic. First, we calibrate the straightness of the machine tool sliding guide which is a critical component of the test system and has a function of supporting and orienting, to improve the motion precision of that machine; and second, measure profile of large aspheric optic with the help of NC machine and Heidenhai(MT60); and third, process the test data to further enhance the precision of measurement.
