INTRODUCTION TO DEEP DRAWING
Keywords:deep drawing, metal forming, LDR, formability, anisotropy
Since the beginning of the 21st Century, society has witnessed a great increase in technological advancement and it has been influencing the lifestyle of the people in various ways. In the present scenario of globalisation, advanced technology is at the forefront in all areas of the engineering world. The evolution of this technology in the mechanical engineering industry is glaringly evident in various metal forming operations. Metalworking is one of the important processes used in shaping of the metals in addition to casting, welding, machining, and powder metallurgy. However, the metal forming may be considered as the earliest metalworking operation evolved through the simple hammering of gold and copper. It is playing a central role and industry is actually progressing mainly due to the evolution of this technology [6, 7]. Essentially, the main aim of metal forming operations is to work for transformation of a metal billet into a component with the desired geometry. The demand for further research in lightweight sheet metals and their use in the automobile sector is increasing rapidly due to the shortage of petroleum products.
