koordinatmått

Koordinatmått is a Swedish term that translates to "coordinate measure" or "coordinate dimension" in English. It refers to a method of specifying the size and location of features on a part drawing using coordinate values. Instead of relying on traditional dimensioning techniques that measure distances between lines or points, koordinatmått uses a datum or origin point from which all dimensions are referenced.

In practice, this means that each point or feature on the drawing is defined by its X, Y, and sometimes Z coordinates relative to this established origin. This approach is particularly useful in computer-aided design (CAD) and computer-aided manufacturing (CAM) environments. It allows for precise digital definition of parts, facilitating automated machining processes and ensuring high accuracy in production.

The advantage of using koordinatmått lies in its unambiguous nature and its compatibility with automated systems. It reduces the potential for cumulative errors that can occur with chained dimensions. When manufacturing a part based on koordinatmått, a machine tool can directly interpret the coordinate data and position itself accordingly. This makes it a valuable tool in modern engineering and manufacturing, particularly for complex geometries and high-precision components. The concept is fundamental to geometric dimensioning and tolerancing (GD&T) systems.
