RISComparison of Two Similar Mathematical Models for Tolerance Analysis: T Map and Deviation Domain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The major part of production cost of a manufacturing product is set during the design stage and especially by the tolerancing choice. Therefore, a lot of work involves trying to simulate the impact of these choices and ...
A Framework for Explicating Formal Geometrical and Dimensional Tolerances Schema From Manufacturing Process Plans for Three Dimensional Conformance Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A process plan is an instruction set for the manufacture of parts generated from detailed design drawings or computeraided design (CAD) models. While these plans are highly detailed about machines, tools, fixtures, and ...
Tolerance Analysis and Allocation for Design of a Self Aligning Coupling Assembly Using Tolerance Maps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A selfaligning coupling is used as a vehicle to show that the ToleranceMap (TMap) mathematical model for geometric tolerances can distinguish between related and unrelated actual mating envelopes as described in the ASME/ISO ...
Tolerance-Maps to Model Composite Positional Tolerancing for Patterns of Features
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For the first time, Tolerance-Maps (T-Maps) are constructed to model composite positional tolerancing applied to patterns (arrays) of features. The T-Map for a feature is a range (codomain) of points obtained by mapping ...
Toward Automatic Tolerancing of Mechanical Assemblies: First Order GD&T Schema Development and Tolerance Allocation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Geometric and dimensional tolerances must be determined not only to ensure proper achievement of design function but also for manufacturability and assemblability of mechanical assemblies. We are investigating the degree ...
Toward Automatic Tolerancing of Mechanical Assemblies: Assembly Analyses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Generating geometric dimensioning and tolerancing (GD&T) specifications for mechanical assemblies is a complex and tedious task, an expertise that few mechanical engineers possess. The task is often done by trial and ...
