Abstract: Air bending is one of the most common methods of forming positions from sheet metal. It has found wide use due to the simplicity of the procedure and the possibility of bending any angle by controlling the movement of the upper tool (punch). With this procedure, it is possible to create very complex shapes that can have a large number of bends. In order to form the developed form based on the given bent form, we must accurately determine the K-factor, which is the basic factor that defines the arrangement of the bent lines and the length of the piece in the developed form. There are many parameters that affect the K-factor, among others are the type and thickness of the material being bent. In this paper, it was analyzed whether, and to what extent, the choice of the bottom tool (V-die) affects the K-factor. In the experimental part, test pieces of the same width and length were bent on dies of different widths, and after required measurements and K-factor calculation, the magnitude of this influence was determined.
