But because of their poor rigidity, it is easy to bring machining deformation caused by the existence of the residual stress and the fixing stress.
残余应力及装夹应力容易使刚性差的薄壁件引起较大的加工变形,而传统工艺难以使其达到精度要求。

The machining process of copper reflector is described. A processing method of "simultaneous processing of two sides and natural stress releasing" is put forth.
叙述铜反射镜的加工过程,提出“两面同时加工,自然释放应力”的加工方法。

Experiment results showed that the fracture of the nut was originated from a variety of macro defects, micro defects both by founding and machining, as well as high residual stress.
