“…This allows for two distinct advantages over a normal sheet hydroforming operation. First, the fluid exerts increasing pressure on the back side of the flange which pushes additional material into the working area to replenish material that is being bulged downwards (Thiruvarudchelvan & Travis, 2003). This advantage is mildly analogous to the one seen during a tube hydroforming operation when axial pressures are exerted on the workpiece to induce additional material flow from the periphery to the inner portion of the tube.…”

This paper both summarizes and explores the literature published between 1995 and 2015 on enhancing and extending hydroforming technology. M any different research areas have been proposed, all of which try to enhance the well-established manufacturing process by either improving formability or reducing costs. Each of the technological variations are first described and then their uses, benefits, drawbacks, and applications are discussed and summarized.

“…The hydroforming process generates a growing interest in the automotive, aerospace and gas industries. The hydroforming technology has several advantages over the conventional sheet metal forming processes, such as improving the sheet formability, better surface quality, higher dimensional accuracy, less spring-back and the possibility of forming complicated shapes [8][9][10][11][12]. In recent years, many innovative methods of hydroforming have been proposed such as hydromechanical deep drawing and hydrodynamic deep drawing.…”

Among the sheet metal forming processes, hydrodynamics deep drawing and hydromechanical deep drawing process are two main types of the deep drawing process that can fabricate complicated parts. In the hydroforming process, the blank is formed to the desired shape by applying a considerably high hydraulic pressure. In this article, the selection of the process parameters will be investigated during the manufacturing of a pure copper sharp conical part by finite element analysis and experimental tests. Two finite element models are developed for hydrodynamics deep drawing and hydromechanical deep drawing processes. After verification of the FE model by experimental results, the effect of process parameters includes the applied pressure, friction coefficient, die radius and blank holder force on thinning of the blank are investigated. The thinning ratio of blank is calculated in different zones of the conical part under different working conditions determined according to the Taguchi design of experiment methods. Signal to noise ratio analysis has been carried out and the influence of process parameters on the thinning ratio is determined at different zones of the conical part. The results show that the friction coefficient has an important role in the thinning of the conical nose while at the lateral surface of the cone, the die radius is the most effective parameter on the thinning ratio. The results show that by implementing statistical tools (Taguchi method and signal to noise ratio analysis), it is possible to select the proper process parameters conditions and fabricate defect-free parts. In addition, a non-linear regression equation is developed for prediction of thinning ratio in the hydrodynamics deep drawing and hydromechanical deep drawing processes.
