Abstract

The invention discloses a superhard functional ceramic machining parameter obtaining method, a machining method and application. The obtaining method comprises the following steps that S1, an arc spline curve of a to-be-machined surface is obtained by adopting segmented arc fitting in combination with a double-arc approximation technology; and S2, the inclination angle alpha of a grinding wheel shaft is obtained according to the offset curve; and calculation models of the radius R of a grinding wheel and the diameter d of the grinding wheel shaft are obtained under each interference condition. According to the superhard functional ceramic machining parameter obtaining method, the machining method and the application, the problem of tool-connecting tool marks caused by a multi-time tool-feeding machining mode is solved, and the machining quality of the precise polishing process is improved.

Description

technical field [0001] The invention relates to the technical field of processing superhard functional ceramics, in particular to a method for obtaining processing parameters of superhard functional ceramics, a processing method and an application. Background technique [0002] Superhard functional ceramics (such as magnesium aluminum spinel MgAl 2 o 4 etc.) have important scientific research value and urgent application needs in the military and civilian fields. This kind of material not only has high hardness, but also has good properties such as high temperature resistance, corrosion resistance, wear resistance, impact resistance, high strength, and high electrical insulation. It has good optical transmission performance in ultraviolet, visible light and infrared bands, and it is easy to prepare large-scale high-strength optical transparent devices, and can also be widely used in transparent windows and high-precision temperature measurement devices in high-speed impact ...
