<p>PURPOSE:To make a chip finer with pressure applied to the chip by injecting high pressure liquid to the tip rake face of a cutting tool. CONSTITUTION:Cutting process is carried out by injecting high pressure liquid 5 to the tip-rake face of a cutting tool 2. The chip 6 is spirally curled with a radius of curvature rho. Near the cutting point Q, the material 1 to be machined and the chip 6 become plastic, and in such condition an injection force W of high pressure liquid acts on the chip 6. Thus, since the shearing slip direction varies to produce bending deformation, bending moment is generated at the cutting point Q, so that the chip 6 is continuously curled. As a result, the radius of curvature rho of a curl of the chip 6 becomes smaller and the chip is cut off by shock.</p> |
