Printedonacid-freepaper Springer International Publishing AG Switzerland is part of Springer Science+Business Media (www.springer.com) Preface As the rapid introduction of new designs to the market becomes the key success factor in modern industry, demands arise for lessons in solid modeling and appli- cations. Conventional drawing tables are replaced by CAD and CAE technology, whilemanualmachinesareupgradedwithmoreflexibleandnumericallycontrolled systems on the shop floors. This book addresses scope of lessons primarily for design engineers involved in the disciplines from product design, analysis, and validation. Theoretical backgrounds introduced in this book will help students understandoperationalknowledgeofCAD,CAE,andRapidPrototypingtechnol- ogy, so that engineers can operate or develop design tools in a more efficient manner. Theoretical outlines as well as mathematical examples introduced in the book will help students understand the concept of each theory up to the level of practical use in real-world applications. The general audiences are mechanical ormanufacturingengineerswith little or no coding experience for applicationsof theory, but with limited spreadsheet experiences. The book is designed to enable students to understand and apply theories to practical applications. Therefore, the focus of theories and illustrations in each chapter are prepared to help maximize learningexperiencesfromunderstandingtopracticalapplications.
