The invention relates to a thin-wall component
machining deformation control method which comprises the following steps that a tool is used for
cutting a blank, a
core shell is manufactured, the
core shell is provided with a main shell body and an auxiliary shell body, the outer
diameter of the main shell body is larger than that of the auxiliary shell body, a main end hole is further formed in the main shell body, an auxiliary end hole is further formed in the auxiliary shell body, and a process block is further arranged in the auxiliary end hole; a protective belt is wound on the surface of the main shell, so that the
core shell and the protective belt form a core shell
assembly; partial materials of the main shell and the protective belt are
cut off through a cutter, feature holes are formed in the surface of the core shell
assembly, and then the cutter is used for
cutting off the process blocks; and after the core shell
assembly, the positioning plate and the
machine tool spindle are separated from one another,
machining is finished. By adopting the technical scheme provided by the invention, after the
residual thermal stress in the core shell is greatly released by changing the process sequence, the protection belt is wound, and then the characteristic hole is formed by
cutting, so that the shrinkage deformation difference between the protection belt and the core shell is reduced, and the
machining precision and the appearance quality of the core shell assembly are improved.
