| Abstract: | Based on X/Y/Z 3-axis grinding machine,the arc grinding wheel parallel grinding technology for large square aspherical lens was discussed in this paper.The mechanism of arc wheel parallel grinding was introduced,the key problems,such as on-line mesurement for wheel form error,on-line mesurement and compensation for workpiece form error,were solved.Mean results from many runs of high efficiency precision grinding experiments showed that,the surface form error and surface roughness of 430 mm×430 mm aspherical lens attained PV 4.2 μm and RMS 0.1 μm respectively. |
