英文摘要	针对精密光学系统中对高精度离轴楔形非球面透镜的加工要求,提出采用由倾角可调三轴摆动式数控夹具系统和精密磨床数控系统(COMPuTEr nuMErICAl COnTrOl,CnC)协调完成离轴楔形非球面透镜的高效加工方法。设计三轴摆动式数控夹具机构及控制系统相关程序,完成夹具制造及调整,在数控精密平面磨床上实现对离轴楔形非球面平行磨削加工。倾角可调夹具的设计简化原有的加工工序,提高加工效率。根据平行磨削加工原理对加工插补误差和工件形面误差进行模拟计算,结果表明:夹具旋转误差以及工件的形状尺寸会对加工精度产生较大影响。根据模拟结果和平行磨削方法原理,设计工件加工误差的在位补偿方法。通过平行磨削加工及补偿试验证明:在位补偿方法可以有效提高工件的加工精度。; To satisfy the machining requirement of high-precision off-axis wedge aspheric lens in precision optical system,a grinding method of off-axis wedge aspheric with high efficiency using the coordination of the 3-axis computer numerical control(CNC) clamp and high-precision CNC grinding system is presented.The structure of 3-axis rotation CNC clamp and the control software are designed and achieved.The parallel grinding method of off-axis wedge aspheric lens is realized in the CNC plane grinding machine by using the proposed clamp.It simplifies the grinding process and improves machining efficiency.The interpolation error and machining profile error are simulated according to the principle of parallel grinding.The simulation results show that the rotation errors of clamp and the workpiece's sharp have an effect on the machining accuracy remarkably.Based on the simulation results and the principle of parallel grinding,the onsite compensation method is implemented.The machining and compensation experimental results show that the machining accuracy can be improved effectively through compensation method.; 国家高技术研究发展计划(863计划;2008AA042501);福建省科技重大专项/专题(2006HZ0002-4)资助项目
