What is vibratory stress relief? Is it similar to cryogenics?
Vibratory stress relief is a separate process. It has nothing to do with cryogenics. The block is set to vibrate at it’s resonant frequency for a certain length of time depending on the mass. After a set time elapses, the piece is considered stress relieved. Stress Relief Engineering has a machine called the Formula 62 which is very well suited to this task.
