| 摘 要： | 通过对Φ42 mm和Φ82 mm口径非球面光学零件精密铣磨成型过程的加工特点和加工误差因素的分析,在工艺中引入刀具与工件变形、刀具半径误差等因素,结合经典Hertz接触理论建立了刀具与工件变形量及刀具半径误差和补偿理论模型,并且应用在精密铣磨成型过程中,通过实验,Φ42 mm口径非球面光学零件经一次精密铣磨成型后元件面形精度PV值为1.91μm,RMS值达到0.288μm;Φ82 mm口径非球面光学零件经一次精密铣磨成型后元件面形精度PV值为1.60μm,RMS值达到0.385μm,完全满足加工精度要求,加工时间节省了50%以上。实验验证了理论分析及误差补偿方法的正确性,实现了精密光学非球面元件的快速精密铣磨成型加工。 |
