Introduction

Abstract

Metal forming is an important process since primitive days of human being. It is the process wherein the size and shapes are obtained through the plastic deformation of the material. The stresses induced during the process are greater than the yield strength but less than the fracture strength of the material. The intelligent press forming of sheet metal is a comprehensive subject that combines control science, computer science and sheet metal forming theory. The marked feature is to identify the material properties and friction coefficient in real-time according to the characteristics of the initial piece and utilizing physical quantities that are easy to be measured, so that the forming process can be completed automatically with the optimal processing parameters. The introduction chapter deals with recent development in metal forming operations like deep drawing , rolling, extrusion and bending . The classification of these operations has been covered with suitable information and neat sketches. The important forming parameters and their effect related to these operations are discussed in detail.
