Notes:
Abrasive Suspension Jets (ASJ) is a new micro processing technique developed formicro processing of hard and brittle materials based on the traditional Abrasive Water Jet (AWJ).Based on drilling experiments of glass using MASJ technology, the dependence of materialremoval, the depth and the diameter of the machined holes on the process parameters, such asworking pressure, processing time, standoff distance, incidence angle and concentration ofabrasives were investigated. Experimental results show that the material removal is approximatelyproportional to working pressure, processing time and concentration of abrasives, except thestandoff distance. It is founded that the processing time is the most remarkable influence factor onthe material removal and the depth of the holes. But the working pressure doesn’t show obviouseffects to the material removal and the depth of hole with lower pressure in MASJ. The increaseof standoff distance will decrease the material removal and depth of hole, and the concentration ofabrasives can improve a few of drilling ability. Further, it is founded that longer processing timeand smaller standoff distance will achieve higher MASJ drilling efficiency and better quality ofhole, with 90 degree jet incidence angle
