This paper reports the design and implementation of a system for automatic recognition of
features from freeform surface CAD models of sheet metal parts represented in STL format …

Feature modelling is nowadays the predominant way of product modelling, in which
geometric and functional information is stored in a single product model. The basic concepts …

This paper presents a new algorithm for extracting Free-Form Surface Features (FFSFs) from
a surface model. The extraction algorithm is based on a modified taxonomy of FFSFs from …

A flexible manufacturing system is capable of dealing with changes and uncertainties
occurring in a manufacturing environment. A rigid automation system adapts changes …

Form feature modeling is a much used shape modeling technique that offers high-level
control over a shape. When a feature-based interpretation of shape data is not available, eg …

Complexity of sculptured surfaces has a great influence on multi-axis computer numerical
control (CNC) machining performances such as processing efficiency, surface quality, and …

In the past, several methods for feature definition have been proposed, most recently for
freeform features. Among these methods are several examples of user-driven feature …

Feature recognition techniques have been developed in the past that dealt with
parameterizing regular features. In response to the availability of free form shape …

Free-form surface features (FFSFs) extraction is one of the key issues for redesigning and
reediting the surface models exported from commercial software or reconstructed by reverse …

Reverse Engineering (RE) is an activity which consists in digitizing a real part in order to
create a numerical or virtual model of it. It is conducted on components that does not have …
