Semantic Tolerance Modeling - An Overview
نویسنده
چکیده
A significant amount of research efforts has been given to explore the mathematical basis for 3D dimensional and geometric tolerance representation, analysis, and synthesis. However, engineering semantics is not maintained in these mathematic models. In this paper, a new semantic tolerance modeling scheme based on modal interval is introduced to improve interpretability of tolerance modeling. With logical quantifiers, semantic relations between tolerance specifications and implications of tolerance stacking are embedded in the mathematic model. Semantic tolerancing also allows for true variation range estimation such that feasible and complete solutions can be obtained.

Semantic Tolerancing
Recently we developed a new tolerance modeling scheme, semantic tolerance modeling, to enable interpretable and accurate tolerance analysis. In this paper, a new dimensioning and tolerancing practice, semantic tolerancing, is proposed with the theoretical support of semantic tolerance modeling. Based on the principles of interpretability, this tolerancing approach allows for better design inten...

A significant amount of research has been performed to explore the mathematical basis for dimensional and geometric tolerance representation, analysis, and synthesis. However, tolerancing semantics such as logical dependency among variations and sequence of specifications is not maintained in these models. Consequently, their numerical results are not interpretable. In this paper, a semantic to...

متن کاملGenerating an Indoor space routing graph using semantic-geometric method
The development of indoor Location-Based Services faces various challenges that one of which is the method of generating indoor routing graph. Due to the weaknesses of purely geometric methods for generating indoor routing graphs, a semantic-geometric method is proposed to cover the existing gaps in combining the semantic and geometric methods in this study. The proposed method uses the CityGML...
