Regenerative chatter in self-interrupted plunge grinding
workpiece interactions, a grinding force is generated, which is exerted on the wheel and the workpiece. For a stable grinding process, displacements of the wheel and the workpiece are constant, and therefore the workpiece profile is round and flat. For an unstable grinding however, the profile becomes wavy and the grinding depth fluctuates.
