A Computer Aided Tolerancing Tool based on Kine- matic Analogies
A computer aided tolerancing tool is presented that assists the designer in functional tolerance specification. The theoretical concepts for subsequent tolerance analysis are also provided. The computer aided tolerancing tool is part of a feature based object oriented (re)–design support system, called FROOM. FROOM’s assembly modelling capabilities provide basic information for functional toler...
متن کاملA CAD based Computer-Aided Tolerancing Model for Machining Processes
The Computer Aided Design (CAD) has been a very important tool for the design and manufacturing in recent years. However, the CAD has often been used as ‘Computer Aided Drafting’ for engineering parts in industry. The ‘design’ part of the CAD is often not very well implemented and by improving on it we can enhance the usefulness of the computer-based component of the manufacturing process. A ty...
متن کاملA computer aided tolerancing tool I: Tolerance specification
In current tolerancng practice, designers have to manually specify tolerances: either on a drawing or in a CAD system. Different designers will possibly arrive at different tolerance specifications for the same nominal geometry. ,The paper demonstrates that this situation can be avoided in the case of functional tolerancing with a focus on the geometry relevant for functioning. Under this restr...
متن کاملA computer aided tolerancing tool II: Tolerance analysis
A computer aided tolerance analysis tool is presented that assists the designer in evaluating worst case quality of assembly after tolerances have been specified. In tolerance analysis calculations, sets of equations are generated. The number of equations can be restricted by using a minimum number of points in which quality of assembly is calculated. The number of points needed depends on the ...
متن کاملComputer Aided Research on Synonymy and Antonymy
This research is a continuation of that reported in Axiomatic Characterization of Synonymy and Antonymy, which was presented at the 1967 International Conference on Computational Linguistics [3]. In that paper on mathematical linguistics the relations of synonymy and antonymy were regarded as ternary relations and their domains and ranges were discussed. Synonymy and antonymy were defined joint...
