Method for reducing machining deformation of irregular-shaped aluminum alloy product

The invention provides a method for reducing machining deformation of an aluminum alloy product in an irregular shape, which comprises the following steps: quenching and aging an aluminum alloy, then carrying out small-amount machining, then carrying out low-temperature or high-temperature annealing, carrying out small-amount machining again, then measuring the dimensional precision, and if the dimensional precision is reached, directly machining the aluminum alloy to a target size, and if the size precision is not reached, low-temperature or high-temperature annealing and a small amount of machining are repeated until the size precision is reached. According to the method provided by the invention, the problem that the dimensional precision of the aluminum alloy product cannot be controlled in the machining stage when the residual stress cannot be reduced by adopting a proper cold deformation method is solved. 本发明提供了一种降低不规则形状铝合金制品机加工变形的方法，包括：将铝合金淬火和时效后进行少量机械加工，然后进行低温或高温退火，再次进行少量机械加工，然后测量尺寸精度，如果达到尺寸精度则直接加工至目标
