Optimization Method of Assembly Tolerance Types Based on Degree of Freedom
Applied Sciences, 2023 The automatic generation of tolerance specifications is an important aspect of achieving digital product design. An obvious feature of the current automatic generation of tolerance based on rule reasoning is that all tolerance types will be inferred for ...

Development and Case Studies of a Function-Based Method for Geometric Tolerance Design [PDF]
한국정밀공학회지, 2018 In order to help design engineers to adopt the Geometric Dimensioning & Tolerancing (GD&T), this paper develops a step-by-step method for tolerance design based on the function of the product and its parts.

Fault-tolerant geometric spanners [PDF]
Proceedings of the nineteenth annual symposium on Computational geometry, 2003 We present two new results about vertex and edge fault-tolerant spanners in Euclidean spaces. We describe the first construction of vertex and edge fault-tolerant spanners having optimal bounds for maximum degree and total cost. We present a greedy algorithm that for any \(t > 1\) and any non-negative integer \(k\), constructs a \(k\)-fault-tolerant ...

Tolerances in Geometric Constraint Problems [PDF]
Reliable Computing, 2005 Geometric constraint solving is a term of computer-aided design and means the problems which arise when the location of geometric objets is described via geometric relations between them. The issues crucial for engineering applications are solvability of constraint problems and the sensitivity to errors.

Proposal of a feature recognition method to reflect design information
Nihon Kikai Gakkai ronbunshu, 2020 Manufacturing industries have tended towards high-mix low-volume production in recent years. As a result, there is always strong impetus to shorten the manufacturing lead time of mechanical products.
