The Impact of the Deformation Redistribution on the Special Narrowing Force

Conference paper
Part of the Lecture Notes in Networks and Systems book series (LNNS, volume 76)


The paper presents the results of experimental investigations of the special narrowing process with two variants of tool construction in the production of the same workpiece. Both tools had three narrowing operations. Deformation analysis was obtained through logarithmic deformation and narrowing ratio, and was performed after each narrowing operation. In laboratory conditions, a deformation force was recorded on a hydraulic test machine with custom manufacturing tools. For the experiments, cylindrical preparations, obtained by deep drawing with the reduction of wall thickness from steel and brass, were used.
