The unique focus of the book is the close symbiotic relationship between design and manufacture. It presents a selection of thirty-three papers ensuing from the fifth International Conference on Integrated Design and Manufacturing in Mechanical Engineering, held at the University of Bath, UK, in April 2004. The contributions are divided in the following sections: two keynotes presenting the general synergies and relationships between the design and manufacturing processes through the concepts of production knowledge and integration; design strategies and methodologies, dealing with the critical element of knowledge in design and manufacturing processes and the methods with which designing can be undertaken collaboratively in an integrated manner; integrated design of manufacturing processes, which aim is to ensure a high quality product meeting all requirements, rapidly and at optimum cost; and design tools for particular applications in which texts optimising local decision have been grouped.
