Tube Hydroforming (THF) is getting an increasing amount of attention in industry. THF has advantages such as weight reduction, high dimensional accuracy, and high rigidity. However, this forming process requires precise control of internal pressure and axial feeding. Additionally, in most cases prebending processes must be performed on the tubes before the hydroforming process can be carried ou...

The tube hydro forming process (THF) is an unconventional metal forming process, where in tube is deformed internally and thus it is forced to expand and conform to the shape of the surrounding die. The performance of this process depends on various parameters like internal pressure, axial loading etc. For FEA simulation, it requires proper combination of material selection, part design and bou...

The purpose of introducing ultrasonic vibrations in the tube hydroforming process is to create more formability by obtaining a lower corner radius, improve thickness distribution of the wall and provide good tribological conditions at the tube and the die interface. Vibrations imposed on the die create alternating gaps which improve the formability in the tube hydroforming process in the presen...

hydroforming process in one of the most effective production method, for improving the drawing ratio in sheet metal forming process. this is due to the fact that in hydroforming process, forming takes place using a punch which drives the part forward via a controlled fluid pressure. in this paper, deep drawing hydroforming for circular punch is investigated. different pressure paths are tested ...
