Standardradie

Standardradie is a term used in geometry and product design to denote a reference radius chosen as a standard for a set of components or drawings. It functions as a nominal radius adopted for dimensioning, tolerancing, and scaling, enabling reuse of templates and library features across parts and assemblies.

Origin and usage

The concept arises in engineering drawing and computer-aided design workflows where consistent rounded features are needed for manufacturability, assembly, and tool access. A standardradie is typically selected from a predefined library and applied to features such as fillets, arcs, and rounded corners. By using a common radius, designers can simplify specifications and reduce variation in production.

Definition details

A standardradie is specified in units such as millimeters or inches, with an allowable tolerance that accounts for manufacturing variation. In practice, multiple standardradie values may exist within a design system to suit different families of parts—for example, smaller radii for electrical enclosures and larger radii for structural housings.

Relation to standards

The concept is related to nominal dimensions, tolerances, and geometric dimensioning and tolerancing (GD&T). It helps communicate how a feature should be produced and measured, and it often intersects with cataloged design rules and manufacturing capabilities.

Examples

A consumer product might apply a standardradie of 2.5 mm to all internal corners, while a mechanical housing could use 6 mm as the standardradie for all external fillets. These choices influence fit, stress distribution, and tool access during fabrication.
