When that happens, this variable load feeds the vibration that already exists, making it worse. "Self-excited vibration" is one term for this phenomenon. "Regeneration of waviness" is another. ordermethis.netWebbAbstract: Self-excited chatter, an instability of the cutting process in combination with the machine structure, is a basic performance limitation of a machine tool.
