Research on Effects of Accuracy in Variable Loading on the High-Pressure Water Jet Incremental Forming

Abstract:

High-pressure Water Jet Increment Sheet Metal Forming adopt the idea of layered manufacturing to scatter a complex three-dimension shape to many 2-dimension layers along z axis, and then the water jet machine partially on these layers. We did a research on that the distance from square processing trajectory to center and the water pressure affect the limits of forming height by finite element simulation of high-pressure water jet box-shape piece incremental forming with the thought of layered manufacturing. Based on this, puts forward a new method of different 2-dimension layers is loaded on different water pressure to improve water jet incremental forming accuracy. This method was proved feasibility by finite element simulation.
