Global Consistency of Tolerances


Book Description

This book contains selected contributions from the 6th CIRP International Seminar on Computer-Aided Tolerancing, which was held on 22-24 March, 1999, at the University of Twente, Enschede, The Netherlands. This volume presents the theory and application of consistent tolerancing. Until recently CADCAM systems did not even address the issue of tolerances and focused purely on nominal geometry. Therefore, CAD data was only of limited use for the downstream processes. The latest generation of CADCAM systems incorporates functionality for tolerance specification. However, the lack of consistency in existing tolerancing standards and everyday tolerancing practice still lead to ill-defined products, excessive manufacturing costs and unexpected failures. Research and improvement of education in tolerancing are hot items today. Global Consistency of Tolerances gives an excellent overview of the recent developments in the field of Computer-Aided Tolerancing, including such topics as tolerance specification; tolerance analysis; tolerance synthesis; tolerance representation; geometric product specification; functional product analysis; statistical tolerancing; education of tolerancing; computational metrology; tolerancing standards; and industrial applications and CAT systems. This book is well suited to users of new generation CADCAM systems who want to use the available tolerancing possibilities properly. It can also be used as a starting point for research activities.

Models for Computer Aided Tolerancing in Design and Manufacturing


Book Description

The contents of this book originate from a collection of selected papers presented at the 9th CIRP International Seminar on CAT held in April, 2005 at Arizona State University, USA. The CIRP plans this seminar every two years, and the book is one in a series of Proceedings on CAT. It contains 33 papers by experts from around the world on subjects that range from theoretical models to practical applications.




Geometric Product Specification and Verification: Integration of Functionality


Book Description

This book focuses in particular on Geometrical Product Specification and Verification which is an integrated tolerancing view and metrology proposed for ISO/TC213. Common geometrical bases for a language allowing to describe both functional specification and inspection procedures are provided. An extended view of the uncertainty concept is also given. Geometric Product Specification and Verification: Functionality Integration is an excellent resource to anyone interested in computer aided tolerancing, as well as CAD/CAM/CAQ. It can also be used as a good starting point for advanced research activity and is a good reference for industrial issues. A global view of geometrical product specification, models for tolerance representation, tolerance analysis, tolerance synthesis, tolerance in manufacturing, tolerance management, tolerance inspection, tolerancing standards, industrial applications and CAT systems are also included.

Constraint-based Reasoning


Book Description

Constraint-based reasoning is an important area of automated reasoning in artificial intelligence, with many applications. These include configuration and design problems, planning and scheduling, temporal and spatial reasoning, defeasible and causal reasoning, machine vision and language understanding, qualitative and diagnostic reasoning, and expert systems. Constraint-Based Reasoning presents current work in the field at several levels: theory, algorithms, languages, applications, and hardware. Constraint-based reasoning has connections to a wide variety of fields, including formal logic, graph theory, relational databases, combinatorial algorithms, operations research, neural networks, truth maintenance, and logic programming. The ideal of describing a problem domain in natural, declarative terms and then letting general deductive mechanisms synthesize individual solutions has to some extent been realized, and even embodied, in programming languages.

Inconsistency Tolerance


Book Description

Inconsistency arises in many areas in advanced computing. Often inconsistency is unwanted, for example in the specification for a plan or in sensor fusion in robotics; however, sometimes inconsistency is useful. Whether inconsistency is unwanted or useful, there is a need to develop tolerance to inconsistency in application technologies such as databases, knowledge bases, and software systems. To address this situation, inconsistency tolerance is being built on foundational technologies for identifying and analyzing inconsistency in information, for representing and reasoning with inconsistent information, for resolving inconsistent information, and for merging inconsistent information. The idea for this book arose out of a Dagstuhl Seminar on the topic held in summer 2003. The nine chapters in this first book devoted to the subject of inconsistency tolerance were carefully invited and anonymously reviewed. The book provides an exciting introduction to this new field.
