Superimposed Oscillation

authored by: Bernd Arno Behrens, Sven Hübner, Hendrik Vogt, Nadezda Missal, Philipp Müller
Abstract: Within the framework of the transfer project T05, the results from the sub-project A7 concerning a superimposed oscillation forming process will be transferred to an industry-oriented axial forming process of the company Felss Systems GmbH. Recursive axial forming serves as the reference model process. Here a gear geometry is axially formed on a hollow shaft by superimposed oscillation in a low frequency range around 15 Hz and in a high amplitude range around a few millimeters. The aim of this project is to gain a deeper knowledge of the influence of a more powerful oscillating device on achievable improvement in mould-filling, in a reduction of forming forces, in an increase in surface quality and in shorter process times. For this purpose, the quality characteristics of the semi-finished workpieces are first determined. A tool system for the integration of the oscillating device into the axial forming process of the company Felss Systems was designed, developed and manufactured. In order to show the comparison between the powerful superimposed oscillation and the conventional recursive axial forming, the superimposed oscillation experiments are both conducted by means of the model process on laboratory level and by industrial recursive axial forming. The evaluation and comparison of the two processes will be conducted with the focus on the project by means of surface inspection, analysis of the form-filling and concentricity to prove and quantify the potential of the TCRC73 technology for industrial processes.
