Feature validation in a feature-based design system
conference contribution
posted on 2014-03-10, 12:16 authored by Keith Case, James Gao, N. GindyThe Loughborough University of Technology Feature-Based Design System (LUTFBDS)
allows detail design to be carried out in a computer aided design (CAD)
environment by the addition of form features to stock material or part-machined
components. An iconic user interface assists in the description parts in terms of a set
of primitive features such as holes, pockets and slots or higher level compound
features such as patterns of holes and counterbored holes. This feature representation
is generated in parallel with the geometric data structure of the underlying boundary
representation solid modeller. The feature representation is useful for a range of
downstream manufacturing activities, but our research focusses on the integration of
CAD with process planning. LUT-FBDS functions allows the designer or manufacturing
engineer to progressively construct the final geometry of a part, and facilities are
provided for the designer to modify parameters which relate to feature dimensions,
location, orientation and relationships with other features. These changes may result in
changes to the feature representation and hence there is a need for feature validation
to ensure the integrity of the model.
