In the present research work the effect of abrasive water jet AWJ machining parameters such as jet operating pressure feed rate standoff distance SOD and concentration of abrasive on kerf width produced on graphite filled glass fiber reinforced epoxy composite is investigated Experiments were conducted based on Taguchi s L 27 orthogonal arrays and the process parameters were
Abrasive water jet machining makes use of the principles of both abrasive jet machining and water jet machining AWJM is a non conventional machining process where material is removed by impact erosion of high pressure high velocity of water and entrained high velocity of grit abrasives on a work piece [5] In the early 60 s O Imanaka University of Tokyo applied pure water for industrial
Chicago Waterjet Inc provides custom abrasive waterjet machining services / water jet cutting services with 6 machines ranging from 26 x 26 cutting table all the way up to 80 x160 serving customers in the Chicago area Southern Wisconsin and Northwest Indiana
Abrasive Water Jet Machining Introduction Abrasive water jet AWJ cutting is a nonconventional machining process in which abrasive grains entrained in a high speed water jet collide with the work piece and erode it A water jet is used to accelerate the abrasive grains and to assist the material removal process WJM is suitable for cutting plastics rubber insulation and most textiles
An abrasive water jet machining device includes an abrasive nozzle assembly 11 that jets ultrahigh pressure water mixed with an abrasive during a cutting process for cutting a workpiece W into a desired shape a catcher cup 12 that collects the ultrahigh pressure water jetted from the abrasive nozzle assembly 11 and a distance adjusting mechanism 13 that adjusts the distance
