Computer-aided design (CAD) Books

Book SynopsisThis book reports on the latest advances in using BIM modelling to achieve the semantic enrichment of objects, allowing them to be used both as multidimensional databases – as comprehensive sources of information for finalizing various types of documentation in the building industry – and as modelling tools for the construction of virtual environments. Having advanced to a new stage of development, BIM modelling is now being applied in a range of increasingly complex contexts, and for various new purposes. This book examines the role that virtual reality and related technologies such as AI and IoT can play in preserving and disseminating our cultural heritage and built environment.

Book SynopsisThis open access book gathers contributions presented at the International Joint Conference on Mechanics, Design Engineering and Advanced Manufacturing (JCM 2020), held as a web conference on June 2–4, 2020. It reports on cutting-edge topics in product design and manufacturing, such as industrial methods for integrated product and process design; innovative design; and computer-aided design. Further topics covered include virtual simulation and reverse engineering; additive manufacturing; product manufacturing; engineering methods in medicine and education; representation techniques; and nautical, aeronautics and aerospace design and modeling. The book is organized into four main parts, reflecting the focus and primary themes of the conference. The contributions presented here not only provide researchers, engineers and experts in a range of industrial engineering subfields with extensive information to support their daily work; they are also intended to stimulate new research directions, advanced applications of the methods discussed and future interdisciplinary collaborations.

Book SynopsisThis book addresses the emerging paradigm of data-driven engineering design. In the big-data era, data is becoming a strategic asset for global manufacturers. This book shows how the power of data can be leveraged to drive the engineering design process, in particular, the early-stage design.Based on novel combinations of standing design methodology and the emerging data science, the book presents a collection of theoretically sound and practically viable design frameworks, which are intended to address a variety of critical design activities including conceptual design, complexity management, smart customization, smart product design, product service integration, and so forth. In addition, it includes a number of detailed case studies to showcase the application of data-driven engineering design. The book concludes with a set of promising research questions that warrant further investigation.Given its scope, the book will appeal to a broad readership, including postgraduate students, researchers, lecturers, and practitioners in the field of engineering design.Table of ContentsData-driven Engineering Design.- User-Generated Content Analysis for Customer Needs Elicitation.- Data-driven Conceptual Design.- Management of Constraints, Complexities, and Contradictions in the Data Era.- Blockchain-based Data-driven Smart Customisation.- Data-driven Design of Smart Product.- Data-driven Smart Product Service System.- Digital Twin for Data-driven Engineering Design.- Enabling Technologies of Data-driven Engineering Design.

Book SynopsisAlgorithms provide the basic foundation for all computational processes. This volume presents algorithms at the foundational level and also at the various levels between this level and the user application. Some of these algorithms are classical and have become well established in the field. This material is therefore a rich source of information and is still relevant and up to date. The basic primitives of computer graphics have remained unchanged: lines, circles, conics, curves and characters. This volume contains reference material in all these areas. The higher levelsof contouring and surface drawing are also well covered. Developments in hardware architectures have continued since the first printing, but the basic principles of hardware/software trade-offs remain valid. This reprint is being published as a Study Edition to make the material more accessible to students and researchers in the field of computer graphics andits applications. The continuing popularity of the original book demonstrates the value and timeliness of its contents.Table of ContentsSection 1.

Book SynopsisDieser Band ist das Ergebnis der mehrjährigen Tätigkeit eines von der Gesellschaft für Informatik (GI) angeregten Arbeitskreises. Das wirtschaftlich eminent wichtige und sich rapide entwickelnde Gebiet der rechnerunterstützten Systeme in der Fertigung zeigte einen großen Bedarf für ein solches Handbuch. Durch dieses Buch soll einerseits dem Experten ein Leitfaden und Nachschlagewerk in die Hand gegeben und andererseits das Management bei der Entscheidungsvorbereitung auf diesem Gebiet unterstützt werden. Es soll eine Hilfestellung sowohl bei der Beurteilung und Auswahl als auch bei der Entwicklung und Einführung solcher Systeme geben. Unter den vielen von Computer Aided Manufacturing beeinflußten Unternehmensbereichen ist besonders die Entwicklung aufzuführen, in der heute häufig schon mit CAD-Techniken gearbeitet wird. Der Bereich CAD wird eingehend in dem ebenfalls von der GI initiierten CAD-Handbuch behandelt und ist daher in dem vorliegenden CAM-Handbuch ausgespart. Das CAD- und das CAM-Handbuch sind somit als zwei sich ergänzende Werke zu betrachten. Der Leser, der sich intensiv mit CAM befaßt, sollte genügend Grundkenntnisse über CAD besitzen, um die Zusammenhänge zwischen diesen beiden Technologien zu verstehen.Table of Contents0 Einführung.- 0.1 Literatur zur Einführung.- 1 Das Unternehmen und sein Umfeld.- 1.1 Vorbemerkungen.- 1.2 Unternehmensziele.- 1.3 Einflüsse des Umfeldes auf die Unternehmensziele.- 1.4 Struktur eines Unternehmens der fertigenden Industrie.- 1.5 Informations-und Materialflüsse im Unternehmen.- 1.6 Unternehmensstrategie.- 1.7 Literatur zu Kapitel 1.- 2 Unternehmen und rechnerunterstützte Produktion.- 2.1 Vorbemerkungen.- 2.2 Begriffe der rechnerunterstützten Produktion.- 2.3 Problemfelder der rechnerunterstützten Produktion.- 2.4 Kosten der Rechnerunterstützung.- 2.5 Literatur zu Kapitel 2.- 3 Arbeitsplanung.- 3.1 Vorbemerkungen.- 3.2 Informationsfluß im Umfeld der Arbeitsplanung.- 3.3 Aufgaben der Arbeitsplanung.- 3.4 Informationsfluß innerhalb der Arbeitsplanung.- 3.5 DV-Unterstützung für die Arbeitsplanung.- 3.6 Wirtschaftlichkeit.- 3.7 Literatur zu Kapitel 3.- 4 NC-Werkzeugmaschinen, Industrieroboter, CNC-Koordinatenmeßgeräte.- 4.1 Vorbemerkungen.- 4.2 NC-Werkzeugmaschinen.- 4.3 Industrieroboter.- 4.4 CNC-Koordinatenmeßgeräte.- 4.5 Zusammenfassung.- 4.6 Literatur zu Kapitel 4.- 5 Fertigung.- 5.1 Vorbemerkungen.- 5.2 Beschreibung des Umfeldes.- 5.3 Informationsfluß in der Fertigung.- 5.4 Rechnerunterstützung bei der Informationsverarbeitung in der Fertigung.- 5.5 Maßnahmen zur Vorbereitung und zum Einsatz von rechnerunterstützten Systemen.- 5.6 Wirtschaftlichkeit von CAM-Systemen.- 5.7 Zusammenfassung.- 5.8 Literatur zu Kapitel 5.- 6 Qualitätssicherung.- 6.1 Vorbemerkungen.- 6.2 Ein idealisiertes Qualitätssicherungssystem.- 6.3 Objekte der Qualitätssicherung.- 6.4 Schnittstellen der rechnerunterstützten Qualitätssicherung.- 6.5 CAQ-Bausteine.- 6.6 Beitrag von CAQ zur Wirtschaftlichkeit von CAM.- 6.7 Literatur zu Kapitel 6.- 7 Integration.- 7.1 Vorbemerkungen.- 7.2 Technische Aspekte.- 7.3 Organisatorische Aspekte.- 7.4 Personelle Aspekte.- 7.5 Literatur zu Kapitel 7.- 8 Auswirkungen der Integration auf die Wirtschaftlichkeit von Investitionen in eine rechnergesteuerte Produktion.- 8.1 Vorbemerkungen.- 8.2 Wirtschaftlichkeitsrelevante Eigenschaften rechnerunterstützter Systeme in der Produktion.- 8.3 Wirkungsanalyse rechnerunterstützter Systeme in der Produktion.- 8.4 Probleme der Investitionsrechnung.- 8.5 Modifiziertes Verfahren der dynamischen Investitionsrechnung.- 8.6 Zusammenfassung.- 8.7 Literatur zu Kapitel 8.- Mitarbeiterliste.
