Here, sustainable development is defined as " development which meets the need of the present without compromising the ability of future generations to meet their own needs ". 1 This chapter defines sustainable development as: A dynamic process which enables all people to realise their potential and improve their quality of life in ways that simultaneously protect and enhance the Earth's life-support systems. 2 Implicit here is that economic, social and environmental dimensions are equally vital and interconnected: – Economic sustainability means economic growth without making undue demands on social or natural resources. – Environmental sustainability means not only minimising impacts on the environment, but building natural resources and safeguarding them for the future. – Social sustainabil...

The recognition process is performed at different levels of detail and is based on topological, morphological and geometric reasoning. Invariant shape characteristics are studied and used for defining shape equivalence relations among features, on which the tuning mechanism provided to the user is based. The system supports the recognition of both classes and specific instances of features.

As a matter of fact, assembling robots are today used only in specific environments like for example electronic board assembly or car mass-production. The main reason of this limited use is the robots high cost and the only apparent flexibility. Complete flexibility requires either evolution of the off-line programming systems which is still complex and machine dependent, and the realisation of efficient and reliable task level planning systems, directly related to both design and programming phases.

Different factors of the product life cycle, such as the manufacturing process, part assembly and quality control, can now all be simultaneously involved in the design phase. To achieve CE traditional ComputerAided Design systems are inadequate. Co-operative product design needs more powerful modelling techniques and geometric representation schemes than those offered by actual commercial CAD systems. In this paper a multiple-view CAD representation, called Intermediate Model, is presented. The Intermediate Model has been defined with the aim to upgrade a traditional CAD system to a feature-based modelling system which allows to represent different context dependent views of the product.

However, these systems are still far from satisfying the industrial need to support an automatic flow from design to production in a concurrent engineering environment. To improve CAD systems in this direction, current research proposes the integration of feature recognition techniques with the design-by-features approach.

A feature-based representation of product models is an essential prerequisite to the development of a new generation of Computer Aided Design systems.

They represent a vital step in the direction of product modelling in Concurrent Engineering. In this paper we present a flexible feature recognition system, in which topological, morphological and geometric information is processed at different levels of detail, providing the user with a mechanism that can be tuned to application needs.
