Metal Forming
INTRODUCTION
Metal forming is the final stage of metallurgical manufacturing permitting to produce metal ware used in national economy as the finished products or as the billet for further processing. Metal forming is the main method of making metal products and semi-finished products. More than 90% of smelted metal is processed by different methods of metal forming. Plastic properties of metals are used during the process of metal forming. That is the ability to change without damage the shape and dimensions in hot and cold condition under the pressure of machining tools. The knowledge of metal forming rules permits to realize the forming at optimum deformation regimes and to use the appropriate main and auxiliary equipment. The variety of methods and kinds of metal forming permits producing the wide range of metal products with high productivity, exact dimensions, required mechanical properties. The development of metallurgical manufacture has resulted in appearance of new kinds of metal forming where the processes of casting and hardening metal reduction are being combined. New technological processes of metal forming give the possibility to shape the product at high strain rate, to obtain the products with especially high mechanical properties, to reduce the number of process stages and equipment used for it.
