1. Geometrical and dimensional Measurement Planning : - a systematic and holistic approach
Sammanfattning : För att försäkra sig om den slutliga kvaliteten på maskinbearbetade komponenter måste tillverkande företag mäta och verifiera de geometriska och dimensionella egenskaperna på komponenter innan dem skickas vidare nedströms till den mer värdeskapande monteringen. Det är idag vanligt att den geometriska och dimensionella mätningen och verifieringen uppstår varje gång då en maskin ställs om, när man startar om eller startar upp en ny produktionslina eller då en produktionsprocess ändras.

2. Visualizing the Effects of Geometrical Variation on Perceived Quality in Early Phases
Sammanfattning : In a perfect world, geometrical variation in a manufacturing process would not exist. Every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. LÄS MER
3. Towards Efficient Evaluation of Impacts of Geometrical Variation on Perceived Quality in Early Phases
Sammanfattning : In a perfect world, manufacturing would lead to components without geometrical variation. This would mean that every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. LÄS MER
4. Towards improvement of geometrical quality for manual assembly parts
Sammanfattning : Geometrical variation affects all mass-produced products. This variation will lead to deviations from the nominal design of the product both in terms of aesthetical and functional properties. Geometrical variation originates either from the manufacturing of the parts or from the assembly process. LÄS MER
5. IMPROVING GEOMETRICAL QUALITY BY INDIVIDUALIZING THE ASSEMBLY PROCESS
Sammanfattning : Dimensional deviations are a consequence of the mass production of parts. These deviations can be controlled by tightening production tolerances. However, this solution is not always desired because it increases production costs. LÄS MER
