festgeklemmt

Festgeklemmt is a German adjective formed from the verb festklemmen and describes the state of an object that has been clamped firmly in place. In technical contexts it refers to a workpiece or component that is held rigidly by a clamp, vise, fixture, or other clamping element so that it does not move during processing or assembly.

In machining and manufacturing, a workpiece is festgeklemmt when it is secured for operations such as milling, turning, drilling, or welding. The term appears in instructions and process descriptions: Das Werkstück ist festgeklemmt. It implies sufficient rigidity of the clamping setup and often calls for measures to prevent distortion, such as using parallels, soft jaws, or shims.

Safe handling and design considerations include avoiding over-tightening, which can cause indentations, bending, or surface damage. Clamping arrangements should provide adequate accessibility for tooling and inspection, and should minimize interference with tool travel. Proper alignment and support help ensure that the piece remains festgeklemmt without inducing unwanted stresses.

Etymology and usage notes: festgeklemmt is widely used in German-speaking manufacturing, engineering, and carpentry to describe a secured, immovable state created by clamping. It is distinct from terms describing a piece that is simply stuck or jammed due to friction, such as festsitzen.
