The flexibility and cool cutting characteristics of the abraslive water jet(AWJ) make it an important tool for cutting applications of new materials such as composites and sandwiched materials that are difficult to machine with traditional machining processes[4].
Normally, the lower the materials intensity, the bigger the brittleness ,the higher speed we will need.
So when cutting composite materials with AWJ, we should use low speed under small pressure.
