RISApplied Tests of Design Skills—Part III: Abstract Reasoning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Past studies have identified the following cognitive skills relevant to conceptual design: divergent thinking, spatial reasoning, visual thinking, abstract reasoning, and problem formulation (PF). Standardized tests are ...
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 ...
Applied Tests of Design Skills—Part II: Visual Thinking
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A number of cognitive skills relevant to conceptual design have been previously identified: divergent thinking, visual thinking, spatial reasoning, qualitative reasoning, and problem formulation. A battery of standardized ...
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 ...
Design Ideator: A Conceptual Design Toolbox
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Computer tools for embodiment and detailed engineering design (computer-aided design (CAD)) evolved rapidly in the past 35 years and are now pervasive throughout the industry. But todays commercial CAD is geometry-centric, ...
Statistical Tolerance Analysis With Sensitivities Established From Tolerance-Maps and Deviation Spaces
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Math models aid designers in assessing relationships between tolerances that contribute to variations of a dependent dimension that must be controlled to achieve some design function at a target (functional) feature. The ...
Mathematical Tools for Building Setup-Maps to Optimally Locate Each Casting in a Machining Fixture: Case Study With Minimum Wall Thickness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel combination of mathematical tools underlies a method to lower cost of the first fixture-setup required to finish-machine surfaces on large castings or weldments where components will be attached. The computer-aided ...
Problem Map: An Ontological Framework for a Computational Study of Problem Formulation in Engineering Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Studies of design cognition often face two challenges. One is a lack of formal cognitive models of design processes that have the appropriate granularity: fine enough to distinguish differences among individuals and coarse ...
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 ...
