Lapping Model of Processing Aspheric Parts by the Method of the Lapping Tool of Bending and Forming

磨具弯曲成形法是加工光学非球面零件的新方法,是线接触研磨过程。给出了弯曲成形法研磨的原理,基于Preston方程,限定磨具弯曲成形法特定研磨条件,分析了加工面上的任意一点的压力函数和相对速度函数,推导了磨具弯曲成形法研磨材料去除量函数表达式,推导了研磨作用时间函数。该研磨模型为磨具弯曲成形法研磨实践提供了理论依据。

Processing of optical aspheric parts by the lapping tool of bending and forming is a new method and the processing is line contact. The lapping principle of the bending and forming method is given. Based on the Preston equation, the specific lapping conditions is put forward to the bending and forming method. Analysis is made about the function of the pressure and the relative velocity on the any point of at the processing surface. The material removal function is deduced about the bending and forming method, and the lapping time function is verified to be accurate. The lapping model is an important theory basis for the processing practice of the bending formation method.
