Abstract

The invention discloses a processing deformation control method in the milling process of an aluminum alloy thick plate. The processing deformation control method of the aluminum alloy thick plate milling process comprises the following steps: Step 1: Establish a blank finite element model, its length is L, width is W, and height is H; Step 2: Groove on the blank, the groove depth is h 0 , the slot width is W 0 , the groove length is L 0 ;Step 3: In the ABAQUS software, according to the shape of the groove and the part and the initial residual stress distribution of the blank, divide the unit separation surface in the blank, and generate a mesh; Step 4: According to the material that needs to be removed during the processing of the part and its removal sequence Define the set of slot elements and the set of part elements and nodes respectively. The processing deformation control method of the aluminum alloy thick plate milling process of the present invention has a better effect of suppressing the processing deformation of the aluminum alloy member.

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...
