| Abstract: | According to the model of cutting for abrasive water jet,jet parameters such as the driving pressure, abrasive concentration stand off distance and sidesway velocity influence on the cutting depth and the cutting specific energy are discussed while PREMAJET cut metal steel plate by testing. Problems of the present system are describled, some of the problems will be solved in the future. |
