[0002] There are many items that require testing when aviation aluminum alloy materials leave the factory. The sampling positions of different testing items on the aluminum alloy plate samples are different. For example, the room temperature tensile performance requires testing in the longitudinal, transverse and height directions. The exfoliation corrosion performance requires sampling at the 1 / 10 thickness position of the aluminum alloy plate sample. The fatigue performance sampling requires sampling at the 1 / 2 thickness center of the aluminum alloy plate sample. At present, when aviation aluminum alloy materials are tested at the factory, they are usually calibrated manually at the sampling position center of the aluminum alloy plate sample using a ruler, and then marked according to the size of the sample blank.
