ABSTRACT:
A metal turning chip breaking apparatus includes an impulse actuator in the form of a piezoelectric element that rapidly expands and contracts in response to a rapidly applied and removed voltage. This, in turn, is used to impulsively move a cutter support in a matching fashion, causing a cutter to rapidly withdraw from and return to the cut in a chopping action. This breaks up the chip, which would otherwise form continuously. There is no need to synchronize the incremental motion of the cutter with the rotation of the workpiece.
