  text: "<jats:title>Abstract</jats:title>\r\n                  <jats:p>The increasing
    use of thin-walled profiles in automotive battery housing construction is leading
    to a growing demand for one-sided access mechanical fasteners. Currently, the
    installation of blind rivet nuts still requires pre-drilling using chip-forming
    operations. In Meschut and Meyer (Vorlochfreies Setzen von Funktionselementen
    mittels Fließformen, Europäische Forschungsgesellschaft für Blechverarbeitung
    e.V. (EFB), Hannover, 2021), a chipless, two-step method for installing blind
    rivet nuts was developed, in which flow-drilling is the initial step. To eliminate
    the pre-drilling operation and optimise the joining process of blind rivet nuts,
    a pilot-hole-free joining method using a flow-drilling process is being pursued.
    The use of these blind rivet nuts can significantly simplify the joining process
    by eliminating chip-forming pre-drilling operations. Additionally, the screw-through
    capability reduces screw variance in automated fastening, optimising the feeding
    process by minimising the risk of incorrect screw selection. This work aims to
    develop a single-step process for the installation of a blind rivet nut. To achieve
    this, it is necessary to design the geometries of both the blind rivet nut and
    the flow-drill former, which also serves as the mandrel for the blind rivet nut.
    In addition to the geometries of the tools and functional elements, the flow-drilling
    process itself has been developed. Special attention is given to the pull-through
    and the formation of the closing head. To optimise the closing head formation,
    an iterative optimization process was used. The quality of the pull-through is
    improved by varying the tip geometries and adjusting the process parameters during
    flow-drilling.</jats:p>"
