shortradius

Shortradius is a term used in engineering, design, and related fields to describe a small radius of curvature applied to a corner or edge of a part, component, or feature. There is no single formal definition or universally adopted standard for shortradius, and the term often appears in informal guidelines or CAD discussions rather than in official specifications.

In geometry and computer-aided design, a shortradius typically refers to a fillet or rounded transition with a relatively small radius compared with the surrounding features. This can influence how a part fits with other components, how it distributes stress, and how it behaves under manufacturing processes. Choosing a shortradius involves trade-offs among clearance, strength, surface finish, and manufacturability. Smaller radii may complicate milling or molding operations, while larger radii can improve flow and reduce stress concentrations but may conflict with space or weight constraints.

In manufacturing and mechanical engineering, the concept is used to balance functional requirements with process capabilities. For example, a shortradius can help minimize sharp edges that cause stress risers, but excessive rounding can interfere with assembly, mating parts, or labeled tolerances. Designers often consult process-specific guidelines to determine acceptable ranges for radii in the context of materials, tools, and production methods.

Related terms include radius of curvature, fillet, chamfer, and bend radius, each describing different ways to modify transitions between surfaces. Because shortradius is not a standardized term, its interpretation may vary between industries, organizations, and individual projects.
