Abstract

The invention discloses a machining deformation control method in the milling process of an aluminum alloy thick plate. The machining deformation control method in the milling process of the thick aluminum alloy plate comprises the following steps: 1, a blank finite element model is established, and the length of the blank finite element model is L, the width of the blank finite element model is W, and the height of the blank finite element model is H; 2, a groove is formed in the blank, wherein the groove depth is H0, the groove width is W0, and the groove length is L0; 3, unit separation faces are divided in the blank in ABAQUS software according to the shapes of the grooves and the parts and the initial residual stress distribution state of the blank, and grids are generated; 4, a groove unit set and a part unit and node set are defined according to materials needing to be removed in the part machining process and the removing sequence of the materials. According to the machining deformation control method in the milling process of the thick aluminum alloy plate, the effect of inhibiting machining deformation of the aluminum alloy component is good.

Description

technical field [0001] The invention relates to an aluminum alloy thick plate milling processing technology, in particular to a processing deformation control method in the aluminum alloy thick plate milling process. Background technique [0002] With the continuous development of the aviation manufacturing industry, the requirements for the performance of modern aircraft and spacecraft continue to increase, and the overall structural parts are more and more used in actual production. The overall structure is smooth in appearance and light in weight. It is better than the riveted structure in terms of stiffness, fatigue strength and various instability critical values. The application of integral structural parts is a great progress in the aviation manufacturing industry. However, due to the more complex shape of the overall structural part, the higher material removal rate, and the more stringent requirements for machining accuracy, the overall structural part is often acc...
