A datum is a concept that is widely used in mechanical manufacturing. It is employed in various aspects such as specifying part dimensions during design, positioning workpieces during manufacturing, measuring dimensions during inspection, and determining the assembly positions of components during assembly. A datum is a point, line, or surface used as a reference to determine the geometric relationships on a manufactured object.
A benchmark is a model, an example, a standard
References are the points, lines, and surfaces on a part that are used as a basis for determining the positions of other points, lines, and surfaces.
The dimensions and positions of components are relative, that is, they are defined with respect to a certain position, which is known as the reference point
