Keilwinkel

Keilwinkel is a German term that literally translates to wedge angle. In geometry and engineering, it denotes the angle formed by the two planar faces of a wedge or bevel. The Keilwinkel is a key parameter in the design and analysis of wedges used to split, lift, clamp, or seat components, and in the production of beveled surfaces and joints. In technical drawings, the Keilwinkel is typically specified in degrees and influences force transmission, contact geometry, and tolerances between mating parts. The concept also appears in optics and related instruments where a wedge’s angle affects optical path differences.

Etymology and usage: The word combines Keil (wedge) and Winkel (angle), reflecting its role as a descriptive term for a geometric or mechanical feature. While most common in technical contexts, it can appear in regional or historical texts discussing wedges, bevels, dovetails, or similar components.

Other uses: Keilwinkel may also occur as a surname or as part of a place name in German-speaking regions, but there are no widely documented, notable exemplars in major reference works. If encountered in a regional context, it is advisable to consult local gazetteers or genealogical resources for precise disambiguation.
