Towards easier and more functional semantics for geometrical tolerancing
Geometrical defects of a manufactured feature are limited by form, size and location tolerances. The standardized semantics of those tolerances, i.e. their interpretation on the manufactured feature, presents a lot of drawbacks. We propose new semantics, based on the fitting of a unique theoretical feature on the manufactured feature. The fitting criterion we propose, named minimum volume crite...
متن کاملCad-based Dimensional and Geometrical Tolerancing Implementation by the Use of Virtual Gages: a Case Study
Physical gages permit verification with low uncertainties but remain expensive and inflexible. With the development of 3D CAD modellers and the progress made in coordinate measuring machines, the concept of the virtual gage appeared. The paper focuses on the implementation rather than the inspection of dimensional and geometrical tolerancing in 3D-CAD models of mechanical assemblies by the use ...
متن کاملA Systematic Approach for Geometrical and Dimensional Tolerancing in Reverse Engineering
In the fields of mechanical engineering and industrial manufacturing the term Reverse Engineering (RE) refers to the process of creating engineering design data from existing parts and/or assemblies. While conventional engineering transforms engineering concepts and models into real parts, in the reverse engineering approach real parts are transformed into engineering models and concepts (Várad...

متن کاملSemantic 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...
