Abstract

The proper alignment of the tool and the workpiece in a curve generator is essential for manufacturing precision optics. Misalignments result in deviation from the desired shape of the lens. We summarize the development of desktop software which predict the amount of deviation of a generated spherical surface from a perfect sphere in terms of the misalignment between the axes of the tool and the workpiece. The software can be used to create a database correlating surface errors and axes misalignments. Such a database is of use to operators of curve generating machines, such as the Opticam SM and Opticam SX, who may thus be able quantitatively to predict the amount of correction required to remove a given amount of surface error.
确定性微磨削中静态刀具失位引起的表面误差
曲线发生器中刀具与工件的正确对中是精密光学加工的关键。不对准会导致与期望的透镜形状发生偏差。我们总结了桌面软件的发展,该软件可以根据刀具和工件轴线之间的不对准来预测生成的球面与完美球体的偏差量。该软件可用于创建一个数据库,将表面误差和轴不对中相关联。这样的数据库对于曲线生成机(如Opticam SM和Opticam SX)的操作人员很有用,他们可以定量地预测去除给定表面误差所需的校正量。
