The invention discloses a processing method for a cabin assembly of a ceramic matrix composite material. Taking the metal end surface of a workpiece as a reference, the flatness of the metal end surface is leveled to be less than or equal to a first preset value; Initially determine the center of the workpiece as a benchmark, and rough-machine the shape of the workpiece to leave a machining allowance. Among them, the bottom hole of the pin hole is processed on the metal end surface of the workpiece: the eddy current test whether the machining allowance is uniform; After the amount is uniform, the shape of the workpiece is finished to the size; the flatness of the metal end face is leveled based on the metal end face is less than or equal to the second preset value; the center of the workpiece is determined again based on the shape of the workpiece after finishing to size, and the metal is processed. End face to dimension. The invention solves the technical problem that it is difficult to control uneven wall thickness caused by machining deformation when processing the cabin assembly of ceramic matrix composite material, and improves the product precision of the cabin section assembly of ceramic matrix composite material.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing method for a cabin component of a ceramic matrix composite material. Background technique [0002] In recent years, with the continuous advancement of science and technology, material technology has developed rapidly. Composite materials have gradually become one of the dominant materials. Composite materials have the characteristics of light weight, high specific strength, specific modulus, corrosion resistance, high temperature resistance, and ablation resistance. They are ideal materials for weapons such as aircraft, missiles, and aerospace vehicles. "Metal + composite material" is a kind of structural part that is relatively common in missile weapon systems at present, and is currently mainly manufactured by winding, suiting and other technologies. As an emerging composite material, ceramic matrix composites have stronger corrosion res...
