N2 - The computer aided programming system was developed, which could compute the coordinates and generate the CNC programs automatically. On the premise of waviness controlling, the raster grinding trajectory was optimized. To acquire the radius and form error of diamond wheel, the measurement by a corkscrew spin trajectory was proposed. By precision tool setting, the definitive position between wheel and element was established. Through on-machine measurement, the 3D form error of optics was acquired, which was combined with the theoretical coordinates of aspheric to compensation grinding. In the end the grinding experiment was carried out. The material removal rate of rough grinding, semi-fine grinding and fine grinding were about 466.7 mm3/s, 10.5 mm3/s and 2.3 mm3/s, respectively. The P-V of form error after fine grinding was about 3.21μm. The destination of highly active and ultra-precision grinding of large aperture and complex aspheric lens was achieved.
