The effective friction at the die-workpiece interface is very significant during forging processes, because it basically influences the process parameters. This outlines the background of the development of this project, in which the expressiveness of the Ring-On-Disc-Test should be analyzed under forging conditions. This test is usually used for friction evaluation in the area of mechanical engineering. Thus the task was to design, construct and commission a testing facility, which reflects the Ring-On-Disc-Test under real forging conditions. In this work fundamentals about friction, the...
