等离子电弧加热弯曲成形还可以降低机械加工引起的残余应力，有效减少回弹。

The plasma arc forming can also decrease the residual stresses caused in the mechanical processes, which can be of great significance in preventing rebounding.

然而，对于由机械加工获得的金属机械零件，必须考虑零件内存在的残余应力对热变形误差的影响。

However, for the metal mechanical parts which are processed by mechanical method, the influence of its inner residual stress on the thermal deformation error should be considered.
