The Experiment Study of Water Jet Incremental Sheet Metal Forming
For the manufacture of panel parts, incremental sheet metal forming is significant in reality. This study put forward a method of incremental sheet metal forming: High-handed water jet with constant pressure and speed that caused by high pressure system acts on sheet metal and makes it out of shape, following transmutation superposition the requisite parts can be made. Based on this theory, a system of incremental sheet metal forming by using water jet is designed. At the same time, a forming experiment device is developed which is used to test the influence of water jet pressure, sheet metal thick, target distance to forming result. Finally, the optimized technological parameters of forming will be obtained. Within the work range, the higher pressure of water jet is, the more obvious forming result will be, and a great target distance will make forming result worse, besides sheet metal thick can make a difference of it. If sheet metal thick is invariable, there is interaction among pressure, target distance and feed velocity, so they influence forming result together.
