An important element for the integration of CAD/CAM is the representation and handling
of data used during the design and manufacturing activities. The use of features and product
modelling techniques bring a better handling of this data and provide CAD/CAM with an excellent
platform for integration. The thesis explores the use of a predefined set of features in a product
modelling environment for the design and machining of rotational components.
Theword features in this research implies a set of functional, geometrical and technological
information with a unique form. Those features are pre-defined and comprise of a limited number
of elements which carry the information related to design and manufacturing activities.
The thesis is divided into three main parts. The first part contains a review of topics related
to the research e. g. group technology, component features, CAD/CAM and also contains a
literature survey of related research works.
In the second part the "features" are defined and presented. Also the product modelling
environment is explained and the basic rule based procedures which are used to automatize
the operation planning activities are presented.
In the last part a description of the case-studies used for automatic NC code generation
is presented followed by a discussion of the results. Lastly, the conclusions are drawn and ideas
for further work presented.
A Doctoral Thesis. Submitted in partial fulfillment of the requirements for the award of Doctor of Philosophy of Loughborough University.
