Embodiment 1

[0068] The method for obtaining processing parameters of superhard functional ceramics includes the following steps:

[0069] S1. Use segmented arc fitting, combined with double arc approximation technology, to obtain the arc spline curve of the inner surface of the superhard functional ceramic to be processed; the inner surface curve is generally an aspherical curve, such as figure 1 As shown, the arc spline fitting effect and enlarged view of the inner profile are as follows image 3 and Figure 4 shown;

[0070] Among them, the aspheric parameter equation is as follows:

[0071]

[0072] In the formula, R is the radius of the base circle, K is the cone parameter, A, B, C and D are the quartic coefficient, hexadecimal coefficient, octagonal coefficient and decadal coefficient, respectively;

[0073] The specific process of obtaining the arc spline curve is as follows:

[0074] Obtain the aspheric parameter equation and the coordinate information of the head and end po...

Abstract

The invention discloses a method for obtaining processing parameters of superhard functional ceramics, a processing method, and an application. The obtaining method includes the following steps: S1. Using segmented arc fitting, combined with double arc approximation technology, to obtain a circular arc spline on a surface to be processed curve; S2, first obtain the inclination angle α of the grinding wheel shaft according to the offset curve; then, under each interference condition, obtain the calculation model of the radius R of the grinding wheel and the diameter d of the grinding wheel shaft. The invention solves the problem of tool pick marks caused by the multi-pass processing method, so as to improve the processing quality of the precision polishing process.

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 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. Such materials not only have high hardness, but also have high temperature resistance, corrosion resistance, wear resistance, impact resistance, high strength, high electrical insulation, etc. Good characteristics, it has good optical transmission performance in ultraviolet, visible light and infrared bands, and it is easy to prepare large-scale high-strength optically transparent devices, and can also be widely used in high-speed impact experiments. Wave fairings for precision guided weapons, transparent armor for a...
