STUDY ON DIFFERENT TYPES OF METAL FORMING PROCESS
Main Article Content
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.Finite element method (FEM) is used for simulating complex intricate shapes of industrial sheet forming operation. Effective physical parameters, as well as numerical solution, influence parameters of this phenomenon and its numerical prediction of results. In this review, the applications of FEM for analysing various parameters such as blank Thickness, blank holding force, Material, coefficient of Friction on specimens of materials are discussed. The numerical results are found from literature survey to be in good agreement with the experimental results and accurate thinning distributions had been predict.
