摘要
针对自由曲面光学组件的超精密制造这门崭新技术,开发出从自由曲面光学设计、CAD连续数据转化、自由曲面模型重构、多轴加工仿真与切削优化、加工误差补偿到自由曲面面形测量的集成制造信息平台。所开发的集成技术,能有效减少在同类多轴机床编写复杂数控程序的时间,优化加工条件与切削策略,针对不同类型的自由曲面光学零件的主工艺,进行数字化仿真,避免昂贵的反复试切试验,以及提高产品的面形精度。并通过一系列的试验来验证该集成平台的稳定性和有效性。
Ultra-precision machining technology plays an important role in the manufacture of advanced freeform optics. An integrated manufacturing platform is developed to cover freeform optics design,CAD continuous data transform,freeform model re-construction,simulation and cutting optimization of multi-axis machining,compensation of machining errors,and the measurement and characterization of freeform surfaces. The adoption of the platform technology shortens the time to develop complex NC programs for different multi-axis machine tools to manufacture different types of freeform optics. This system helps to avoid expensive repeated cutting tests,as well as to improve the surface quality of freeform products. The stability and effectiveness of the proposed integrated platform are verified through a series of tests.
