ABSTRACT:
A method for stress-relieving a flame-hardened component by vibrating the workpiece as it is being flame-hardened, and then vibrating the workpiece after it has been flame-hardened, measuring the workpiece to detect warpage, straightening the workpiece to remove the warpage, and then vibrating the workpiece to remove any stresses created by the straightening step.
