The project is designed to develop the latest, competitive technologies and designs of stamping equipment for the manufacture of artillery shells, which is relevant to increase Ukraine's defense capabilities. Technology development is performed in two directions. The first age includes increased productivity and cost reduction through the use of the latest developments in hot extrusion of hollow semi-finished products and hot and cold stamping by drawing with thinning and crimping at the end of operations.

Developed new technological foundations of obtaining the hollow articles by forming cold sheet stamping processes, including drawing, reducing and bulging. The novelty lies in the development of new methods of drawing, reducing and bulging, to create and use a special profiles deforming tool. Using this deforming tool provides a significant reduction of friction influence in the forming of articles, reduce deformation force and increase the degree of deformation in one stage.

Reducing the number of transitions of manufacturing products and the increase in the degree of deformation at a transition in shaping sheet metal forming processes can improve the performance of manufacturing and makes the resulting products competitive.

Information technology for determination of parameters at a design stage of manufacturing techniques of articles with ensured reliability and durability is created by methods of cold forging and a sheet-metal forming.

The classification of sheet metal processes and cold forging processes was made, the expediency of developing of new ways of forming which provide the productivity of manufacturing and the reliability and durability of produced products were grounded.
