Abstract

The invention discloses a method for machining an aluminum alloy thin-wall cabin. A position of a milling tool is changed by modifying a machine tool, and in the process of machining a long cylindrical thin-wall part, milling is replaced by turning, and complex thin-wall parts are machined in a turning and milling combined mode. Some large-size sealing grooves of the cabin are machined by a milling method, a high-quality key groove milling tool is adopted, numerical control programming is performed and a circular trace is formed; the machining method has simple machining processes, product yield is high and the products have stable quality; and in the machining process, a spindle rotating speed, feeding amount and other cutting parameters are required strictly, so high surface quality can be guaranteed, and the sealing requirement is met.

Description

technical field [0001] The invention relates to an aluminum alloy machining method, in particular to an improved aluminum alloy thin-walled cabin body machining method. [0002] Background technique [0003] At present, my country's aerospace industry is developing rapidly, and the field of aerospace product manufacturing is expanding. Among my country's aerospace products, cabin products are the main products. The typical cabin structure is large in size, complex in shape, and the cabin wall is thin and difficult to process. The thickness of the side wall skin of the thin-walled shell structure cabin is generally 1mm to 3mm, and the dimensional accuracy and shape tolerance requirements of the cabin are high. These characteristics make it difficult to adopt ordinary machining methods for the blank of the cabin body, the processing procedures are complicated, the processed products are easily deformed, and the yield of finished products is low.
