Abstract

There is nano-topography on axisymmetric aspherical ground surfaces. Usually, the axisymmetric aspherical lens or molding dies are finished by polishing after they are machined by grinding. However, nano-topography cannot be removed by polishing. Nano-topography causes grinding marks, which lowers the accuracy of optical instruments such as lenses. In this research, the formation mechanism of nano-topography on axisymmetric ground surfaces and relationship between the topography and grinding conditions is analyzed theoretically. The results show that the vibration of the grinding wheel causes nano-topography. In addition, grinding marks changes with the variation in the grinding wheel revolution speed and the workpiece revolution speed.
