A mathematica model has been developed that predicts the aspheric surface that a typical optical surfacing machine will produce. The model, which combines two basic assumptions concerning material wear with the kinematics of the machine, has been verified experimentally for the grinding process. In regions of the surface where the tool extends beyond the edge of the workpiece, pressure becomes nonuniform, and the model must be altered. The established model has been used to synthesize those machine strokes required to produce a desired aspheric surface.
已经开发出一种数学模型，该模型可以预测典型光学加工机床所生产的非球面表面。该模型结合了关于材料磨损的两个基本假设和机床的运动学原理，已在磨削过程中通过实验得到验证。在刀具超出工件边缘的表面区域，压力变得不均匀，此时必须对模型进行修改。已建立的模型已用于合成生产所需非球面表面所需的机床行程。
