摘　　要：根据隐形眼镜模具的超精密加工原理和高精度要求,对影响模具加工质量和效率的主要因素进行了综合分析,分析和加工试验证明水平方向的对刀误差是其中最关键的因素。以Nanotech 250 UPL机床为加工设备,结合Zygo轮廓仪的精密检测原理,对水平方向的对刀误差构建了一个基于检测数据的计算模型。通过对不同隐形眼镜型号、尺寸的相应模具进行加工试验证明,该数学模型可以快速、精准地表达出微小对刀误差并进行修正,从而将隐形眼镜模具的超精密加工与检测进行有效集成,大大提高了模具的超精密加工质量和生产效率。This paper is going to analyze the main factors that affect the quality and efficiency of contact lens mold processing comprehensively based on the ultra-precision processing principles and high-precision requirements.The analysis and processing experiments show that the horizontal tool setting error is the most critical factor among them.In this process,a calculation model for the horizontal tool setting error based on the detection data is built by the combination of Nanotech 250 UPL and the precise detection principle of Zygo profiler.It is proved that this mathematical model can indicate and correct minor tool setting errors quickly and accurately based on the processing experiments on the molds of different contact lens models and sizes.With this mathematical model,the ultra-precision processing and testing of contact lens molds will be integrated effectively,and the quality and productivity of ultra-precision processing will be improved greatly.
