Positionierbar

Positionierbar is a German term describing the ability of an object or system to be moved, oriented, or reoriented to a desired position relative to a reference frame or workpiece. The corresponding noun “Positionierbarkeit” denotes this capability as a property or design feature. The concept is widely used across engineering, manufacturing, optics, and automation to denote adjustable or reconfigurable arrangements.

In practical terms, positionierbarkeit refers to components or devices that can be moved or rotated with predictable accuracy. This includes adjustable fixtures, jigs, and clamps, as well as machinery elements such as linear stages, goniometers, and balk bearings. In robotics and automation, positionierbare joints and end effectors enable tools or grippers to reach different positions and orientations. Optical and electronic instruments rely on positionierbare holders and stages to align components, lenses, or samples precisely. Medical devices may use positionierbare guides or supports to accommodate different patients or procedures.

Key performance aspects are range of motion (degrees of freedom), repeatability, total positional error, stability, and rigidity. Design considerations include material strength, tolerances, locking mechanisms, ease of adjustment, and effects of temperature or load on position. Common actuation methods for achieving positionability include screws, dovetail slides, micrometers, linear actuators, and pneumatic or hydraulic systems.

Examples include a microscope stage with X–Y positioning, an adjustable camera mount, and a modular fixtures system in a workshop. Understanding Positionierbarkeit helps engineers select or design components that can be accurately reconfigured for different tasks while maintaining reliability.
