Shape-Machining of Aerospace Composite Components Using Non-Traditional Abrasive Waterjet Cutting Process

The abrasive waterjet technology (AWJ) is a non-traditional method of machining which offers a productive alternative to conventional techniques. Aerospace composite materials although possessing special properties such as high strength to weight ratio and stability, are known to be difficult to machine, or even impossible to be machined by conventional methods. However, by using abrasive waterjet these composite materials can be efficiently machined. In this paper, two-dimensional and three-dimensional AWJ cuttings are addressed and a focus is placed on the challenging three-dimensional waterjet trial and due to its much more complexity involved, very little work has been done so far. The following subjects were studied: Off-line programming and simulation using IGRIP software, setup and control of the three-dimensional system etc. Finally, a few two-dimensional and three-dimensional abrasive waterjet machining conclusions and future research work are given that reflect our ongoing research.
