%X Hydro forming process is one of the new 
technologies in the manufacturing process in which hollow 
pieces and sheet works are formed under fluid pressure. This 
paper deals with the development of a sheet hydro forming 
(SHF) set up and model to predict the deformation caused by 
the hydro forming using Artificial Neural Networks(ANN). 
During the sheet hydro forming (SHF) process, the hydraulic 
pressures were measured and simultaneously the required 
hemispherical products were obtained with dome height and 
specific thickness. To validate result of this set up work, a 
hemispherical part was formed in a fabricated hydro forming 
set up using single sheet. The data used to train the Artificial 
Neural Network (ANN) model was collected from sheet hydro 
forming (SHF) set up that was designed and built in our 
laboratory. Single- and two-hidden-layer feed forward neural 
network models were used to capture the nonlinear correlations 
between the input(hydraulic pressure, thickness and diameter 
of work piece) and output (dome height of deformed product). 
Neural network model was able to predict the deformed dome 
height, thickness of circular sheet with good accuracy.
