| Abstract: | According to the requirement of supper smooth polishing of aspheric optical elements,the polishing head controlling algorithm was researched and realized which is used in supper smooth polishing of aspheric lens.First,function requirement of the software was analyzed from craft view.Overall structure of the software and the processing flow of tool path programming and post processing are extraction.Then,bi-arc fitting algorithm of the generating line of axis-symmetrical aspheric elements is researched.Algorithm of post processing is given against to supper smooth polishing machine structure.At last,supper smooth controlling software is developed based on these algorithms at VC＋＋platform.The NC program generated by this software can be well used in the polishing process. |
