The present research aims to realize .the numerically controlled ultra-precision machning which can easily finish the work into a required shape-by a single apparatus, utilizing the elastic fracture of the order of atomic size. Ultra fine powder particles and water are mixed, and making the rotating sphere of polyurethane rubber approach to the material surface, the state of fluid lubrication of the mixed fluid is realized, so that powder particles in the mixed fluid are made to collide with the surface. Then the elastic fracture of atomic size is achieved. In this report, utilizing the analysis of fluid movement which was introduced in the previous report, the movement of powder particles is calculated. The following results are obtained. (1) The work is machined by the interaction between powder particles and work, and this report shows theoretically and experimentally that the machining characteristics are influenced by the interaction. (2) Furthermore this report shows the effects of thermal change and powder concentration of the mixed fluid on the stock removal theoretically and experimentally.
