Sheet Metal Forming By Water Hammering Machine: A Review

Abstract

In automotive industry with increase in demand to reduction in weight and manufacture complex parts easily without compromising in strength there for the hydro forming process carried out. The aim is to construct the complex part of non uniform cross section with the help of fluid pressure under different operating condition to achieve optimum value of input parameters from which parts is manufacture. The pressurized fluid serves several purposes: (1) Supports the sheet metal from the start to the end of the forming process, thus yielding a better formed part, (2) Delays the onset of material failure and (3)Reduces wrinkle formation.
