Modeling of abrasive water suspension jet cutting process using response surface method

Abstract

In the paper was presented the influence of key machining parameters by Abrasive Water Suspension Jet (AWSJ): abrasive flow rate, working nozzle diameter, and length on the aluminum cutting depth. A high efficiency in the aluminum cutting results from the use of circular motion of the liquid to generate an abrasive water jet. This has become possible due to the special mixer in which the water and abrasive mixture is generated directly under high pressure. The research determined the best dimensions of the working nozzle and level of abrasive flow rate to achieve the biggest cutting depth were achieved.
