ABSTRACT

According to the ultra-precision machining principle and high-precision requirements of contact lens molds, the main factors affecting the quality and efficiency of mold machining were comprehensively analyzed. The analysis and machining tests proved that the tool setting error in the horizontal direction is the most critical factor. Using the Nanotech 250 UPL machine tool as the processing equipment, combined with the precise detection principle of the Zygo profiler, a calculation model based on the detection data was constructed for the tool setting error in the horizontal direction. Through processing experiments on corresponding molds of different contact lens models and sizes, it has been proved that the mathematical model can quickly and accurately express and correct small tool setting errors, thereby effectively integrating ultra-precision machining and testing of contact lens molds, greatly improving The ultra-precision machining quality and production efficiency of the mold are improved.
