Geometric Tolerance Analysis

2011
This chapter focuses on five main literature models of geometric tolerance analysis – vector loop, variational, matrix, Jacobian, and torsor – and makes a comparison between them in order to highlight the advantages and the weaknesses of each, with the goal of providing a criterion for selecting the most suitable one, depending on the application.

Error-Tolerant Geometric Graph Similarity

2018
Graph matching is the task of computing the similarity between two graphs. Error-tolerant graph matching is a type of graph matching, in which a similarity between two graphs is computed based on some tolerance value whereas within exact graph matching a strict one-to-one correspondence is required between two graphs.

Dimensioning with Geometrical Tolerances

2020
The advantages of the geometric specification of a product are here illustrated by converting a traditional 2D coordinate tolerancing drawing using the geometrical tolerance method. The new language of symbols permits the functional requirements of the products to be fully expressed in technical documentation.

Ramp Tolerance Analysis Considering Geometric Errors

IEEE Transactions on Magnetics, 2009
Load/Unload (L/UL) system has many components such as ramp, limiter, lift-tab and so on. In this paper, we focus on ramp and ramp tolerance analysis considering geometric errors such as assembling and manufacturing errors because the large ramp geometric errors bring about unloading fail that means unloading process does not occur.

Concurrent Dimensional and Geometrical Tolerance Balancing

2006 6th World Congress on Intelligent Control and Automation, 2006
An optimal design method for dimensional and geometrical tolerances (DGTs) has been presented and validated. In concurrent design environment, this method can directly allocate required functional assembly DGTs into pertinent process DGTs by using the given process planning of related components.

Geometric Methods of Assigning Tolerances

2005 IEEE Intelligent Data Acquisition and Advanced Computing Systems: Technology and Applications, 2005
The geometrical interpretation of assigning tolerances is used. It allows the maximal tolerances are evaluated in normal ones. The volume of tolerance domain is optimized. Accuracy of calculation is increased for normal distribution of parameters.

Tolerances in computer-aided geometric design

The Visual Computer, 1987
In the design of discrete part shapes, the specification of tolerance constraints can have major consequences for product quality and cost. Traditional methods for tolerance analysis and synthesis are time-consuming and have limited applicability. The thesis of this work is that geometric design systems based on solid modeling technology can be used to

Probabilistic Analysis of Geometric Tolerances

1996
This paper describes a procedure for the statistical analysis of geometric tolerances. The proposed procedure assumes that a manufactured surface lies between two ideal offset surfaces positioned at equal distance from the nominal surface. These surfaces do not represent a tolerance zone, but rather the volume which has the highest probability of ...

Representing Geometric Tolerances in Solid Models

ASME 1992 International Computers in Engineering Conference: Volume 1 — Artificial Intelligence; Expert Systems; CAD/CAM/CAE; Computers in Fluid Mechanics/Thermal Systems, 1992
Abstract ANSI standard Y14.5 defines a set of geometric tolerances to be used to control part variations in manufacturing. With the increasing trend towards replacing drawings with solid models, a representation is needed for expressing these tolerances unambiguously within the context of a solid model. This representation

3D Tolerance analysis involving geometric tolerances

2001
This paper deals with 3D tolerance analysis involving dimensional and geometric tolerances. The tolerances connected with each component of an assembly are simulated by varying randomly the geometry of its part geometric model features. In particular, an original software has been developed to analyse the influence of the tolerances on the geometry of ...
