Abstract

Small scale waviness of aspheric surface inevitably occurs when grinding aspheric surface with grating parallel grinding technology, so aiming at the problem of waviness amplitude and uniformity, this paper theoretically analyses the relationship between grinding processing parameters and aspheric waviness, and designs a single factor experiment to verify the influence of grinding processing parameters on aspheric surface waviness. The processing parameters are determined to minimize the waviness amplitude. Considering the problem of uniformity of waviness, according to the influence of grinding force on uniformity of aspheric waviness in grinding process, down-grinding grating parallel grinding method and up-grinding grating parallel grinding method are used. Experiments verify that down-grinding grating parallel grinding method is the best method to get most uniformity small-scale waviness of aspheric surface. The minimum amplitude is 0.5μm~1.5μm.
