Abstract

A metal workpiece is cut by rotating the workpiece while pressing the cutting edge of a cutting insert thereagainst for removing a chip from the workpiece. A first liquid jet is directed from a first nozzle toward an upper surface of the cutting insert for creating an hydraulic wedge between the cutting insert and the chip, and a second liquid jet is directed from a second nozzle toward a target point disposed above the upper surface of the cutting insert to engage and deflect the chip upwards and backwards.
