The invention discloses a method for grinding a wedge-shaped aspheric surface, relates to an aspheric surface process and provides the method for grinding the wedge-shaped aspheric surface. The method is characterized in that a circular arc diamond emery wheel is selected as the processing tool; according to the characteristic of the machine tool for realizing the three-axis linkage, the method adopts the processing way of fixing work pieces and three-axis linkage of the tool; installation and position of the work pieces; division of the numerical controlling interpolation points; and the track planning and design of the numerical controlling process. The adaptability of the processing tool for the work pieces is analyzed, and the processing is performed by adopting the circular arc diamond emery wheel; the adaptability of the processing and detection means is analyzed, and the method adopts the processing way of fixing the work pieces and three-linear axis linkage of the tool; the shape types of the work pieces are analyzed, the method poses the surface points measuring and processing track planning method suitable for processing the wedge-shaped aspheric surface, which includes the methods such as the linear optical grating type processing, the oblique line envelope processing and the like. The method has the advantages of convenience, stability, high precision and the like,therefore, the method is suitable for popularization and application.
Description
technical field [0001] The invention relates to an aspherical surface processing, in particular to a grinding process method of a wedge-shaped aspherical surface. Background technique [0002] Wedge aspheric lens is a new field of application, its main function is to split light and focus. The wedge-shaped aspheric lens solution with wedge-shaped plane and aspheric surface is adopted to further integrate the original optical system, reduce the number of optical components used, reduce the volume of the optical system, and improve the performance of the optical system. At present, there are still few researches on the processing of wedge-shaped aspheric mirrors, and there is still no clear understanding of the factors affecting its process and processing accuracy.
