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.
