AI Technical Summary

Problems solved by technology

[0003] Hard and brittle materials have inherent characteristics such as high hardness, high brittleness and low fracture toughness, and their processing technology is much worse than other materials, and in the process of cutting workpieces with abrasive water jets, because the jet energy gradually decays with the increase of cutting depth, The slits on the upper and lower surfaces of the workpiece are wide at the top and narrow at the bottom, and the cutting section has a certain taper. At the same time, due to the uneven distribution of the kinetic energy of the jet section and the deflection lag of the jet, there are obvious rough stripes on the cutting section of the abrasive water jet. The above Defects seriously reduce the surface quality of the cut section, limiting the application and development of abrasive water jet
