Computer Aided Design and Manufacturing Book Excerpt:

Manufacturing contributes to over 60 % of the gross national product of the highly industrialized nations of Europe. The advances in mechanization and automation in manufacturing of international competitors are seriously challenging the market position of the European countries in different areas. Thus it becomes necessary to increase significantly the productivity of European industry. This has prompted many governments to support the development of new automation resources. Good engineers are also needed to develop the required automation tools and to apply these to manufacturing. It is the purpose ofthis book to discuss new research results in manufacturing with engineers who face the challenge of building tomor row's factories. Early automation efforts were centered around mechanical gear-and-cam technology and hardwired electrical control circuits. Because of the decreasing life cycle of most new products and the enormous model diversification, factories cannot be automated efficiently any more by these conventional technologies. With the digital computer, its fast calculation speed and large memory capacity, a new tool was created which can substantially improve the productivity of manufactur ing processes. The computer can directly control production and quality assurance functions and adapt itself quickly to changing customer orders and new products.

Product Design for Modularity Book Excerpt:

The current marketplace is undergoing an accelerated pace of change that challenges corporations to innovate new techniques to respond rapidly to an ever-changing environment. At the center of this changing environment is a new generation of empowered buyers (customers) equipped with fast evolving technologies that allow them to buy from markets scattered across the globe. Empowering the customers has deprived organizations of what was once their right-to introduce new products slowly, at their own leisure. Organizations used to introduce new products every few years, and, for the most part, products offered limited functionalities and features. A low-priced quality product-irrespective of customer satisfaction-was a guaranteed ticket for success. New global economies and global markets changed business practices and focused on the customer as the major player in the economy. Organizations now fail or succeed based upon their ability to respond quickly to changing customer demands and to utilize new technological innovations. In such an environment, the advantage goes to the firm that can offer greater varieties of new products with higher performance and greater overall appeal. In order to compete in this fast-paced global market, organizations need to produce products that can be easily configured to offer distinctive capabilities compared to the competition. Furthermore, organizations need to develop new methods and techniques to react rapidly to required changes in products and market trends and to shorten the product development cycle, which will enable them to gain more economic competitiveness.

Creo Parametric 5 0 Tutorial Book Excerpt:

The eleven lessons in this tutorial introduce you to the design capabilities of Creo Parametric 5.0. The tutorial covers the major concepts and frequently used commands required to advance from a novice to an intermediate user level. Major topics include part and assembly creation, and creation of engineering drawings. Also illustrated are the major functions that make Creo Parametric a parametric solid modeler. Although the commands are presented in a click-by-click manner, an effort has been made, in addition to showing/illustrating the command usage, to explain why certain commands are being used and the relation of feature selection and construction to the overall part design philosophy. Simply knowing where commands can be found is only half the battle. As is pointed out numerous times in the text, creating useful and effective models of parts and assemblies requires advance planning and forethought. Moreover, since error recovery is an important skill, considerable time is spent exploring the created models. In fact, some errors are intentionally induced so that users will become comfortable with the “debugging” phase of model creation. At the end of each lesson is a short quiz reviewing the new topics covered in that chapter. Following the quiz are several simple "exercise" parts that can be created using new commands taught in that lesson. In addition to these an ongoing project throughout the book is also included. This project consists of several parts that are introduced with the early lessons and finally assembled at the end.
