1、VSR Definition
It refers to a physical process of dealing with the metal work piece through vibration power strictly controlled, with a view to solving the problem of instability of dimension and anti-overloading capacity caused by the internal residual stress both during and after processing the work piece. VSR is especially effective to relieve, reduce or homogenize the residual stress within the metal work piece, to improve dynamic and static anti-overloading and distortion-proof capacity of the work piece, and to make sure the dimension and scale accurate.

2、Principle of VSR
The micro-analysis shows that VSR can be taken as an additional stress imposed on the work piece in the form of recycling loading. The alternating stresses imposed on the work piece and the residual stress within the work piece overlap when the work piece is vibrating. When the overlapping of the stresses reach a specific limit, the part where the stress most concentrates will exceeds the yielding limit of the material and distorts , which will reduce the peak value of the residual stress and harden the metal itself. Afterwards, the vibration will work similarly on other parts where the stress concentrates, to the effect that the total value of the overlapping additional vibration stress and the residual stress will not cause any plastic deformation of the work piece, which marks the end of the process to relieve and homogenize the residual stress and harden the metal through vibration.
