Paper Title:
Study on Jet Formation and Modeling for High Pressure Abrasive Water-Jet
  Abstract

High pressure abrasive water jet (HPAWJ) machining has many advantages in hard brittle material processing. In this paper, the hole formation on stone by HPAWJ is analyzed based on brittle and plastic fracture theories. The formation and construction of jet are studied. The distribution of jet velocity, abrasives and energy in the jet-beam section of HPAWJ is analyzed. It is shown that the cross-section of the hole is characterized by a ‘Reverse-bell’ shape on stones by a HPAWJ. The jet velocity of HPAWJ gets lower from jet center to jet margin and it’s distribution is consistent with normal distribution function along with jet center. The concentration of abrasives becomes smaller from jet margin to jet center and it’s distribution is consistent with normal distribution function along with jet margin. The distribution of jet velocity, abrasives and energy in the section of HPAWJ is modeled.
