(4) grasping dynamic behavior of materials by means of cutting
(5) development of a materials design system with a FEM cutting simulation
(6) clarification of high-speed and ultra high-speed cutting mechanism
and physical phenomena arising under ultra high-speed cutting condition
that the cutting speeds is faster than the speeds of the plastic waves
and the plastic shock waves propagate at the plastic shear region.
