What is the German term for the action of bending?

The term "Biegen" is indeed the correct translation for the action of bending in German. In technical contexts, bending refers to the process of deforming a material (often a metal or plastic) by applying a force that causes it to curve. This term is frequently used in engineering and manufacturing settings, describing various processes involved in shaping materials. Understanding the correct terminology is crucial for precision in technical documents and communication.

The other options do not relate to the action of bending. "Baugruppe" refers to a sub-assembly or construction group, while "Adapter" signifies a device that allows incompatible components to connect. "Bleed" is typically used in contexts involving the release of pressure or liquid, and does not convey any meaning related to bending. Hence, "Biegen" is the most appropriate choice in this scenario.
