Machining method of cabin section work-piece

Abstract

The invention provides a machining method of a cabin section work-piece. The work-piece comprises end faces. The method comprises the steps of: determining the planeness of the end faces by taking the end faces of the work-piece as benchmarks; determining a rough machining center of the work-piece by taking pin holes and bottom holes in the end faces as benchmarks; carrying out rough machining on a profile of the work-piece and detecting a machining allowance of each end face; carrying out finish machining on the profile of the work-piece by using a diamond milling cutter according to a preset size; determining a finish machining center of the work-piece by taking the finish-machined profile as a benchmark; carrying out side-edge cutting and bottom-edge cutting on the end faces and end face sealing lug bosses by using a diamond coating milling cutter; carrying out boring-machining on the pin holes in the end faces; pressing out notch edges of a notch by using a pressing plate; and carrying out segmental machining and layered machining on the notch with a preset cutting step length by using a spiral cutting method. Thus, by using a benchmark conversion machining method, the problem of non-uniform wall thicknesses caused by machining deformation in a single benchmark is solved, and the phenomena of scaling-off, breaking-up and delaminating appearing during machining are avoided.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing method for cabin workpieces. Background technique [0002] In recent years, with the continuous advancement of science and technology, material technology has developed rapidly. As a new type of material, composite material has gradually become one of the leading materials in the 21st century. 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 type of structural parts that are relatively common in guided weapon systems. Currently, they are mainly manufactured using technologies such as winding and suiting. [0003] As a new type of composite material, ceramic matrix composites have stronger c...
