The tapping process is one of the most widespread manufacturing processes for internal threads, usually carried out at the end of the value chain. Any non-compliance with required quality standards or even the destruction of the thread due to process uncertainty in the tapping process is therefore subjected to high rework costs. Possible process un...

This chapter describes the various approaches to analyse, quantify and evaluate uncertainty along the phases of the product life cycle. It is based on the previous chapters that introduce a consistent classification of uncertainty and a holistic approach to master the uncertainty of technical systems in mechanical engineering. Here, the following t...

Uncertainty affects all phases of the product life cycle of technical systems, from design and production to their usage, even beyond the phase boundaries. Its identification, analysis and representation are discussed in the previous chapter. Based on the gained knowledge, our specific approach on mastering uncertainty can be applied. These approac...

Decision-making highly relies on the accuracy and veracity of data. Therefore, redundant data acquisition and fusion has established but lack the ability to handle conflicting data correctly. Especially digital twins, which complement physical products with mathematical models, and contribute to redundancy. Uncertainty propagates through the digita...

Reliability of sensor information in today’s highly automated systems is crucial. Neglected and not quantifiable uncertainties lead to lack of knowledge which results in erroneous interpretation of sensor data. Physical redundancy is an often-used approach to reduce the impact of lack of knowledge but in many cases is infeasible and gives no absolu...

Der Leichtbau in Werkzeugmaschinen bietet einen vielversprechenden Ansatz, um die dynamischen Eigenschaften von Maschinen zu verbessern. Dieser ist allerdings meistens mit zusätzlichem Fertigungs- und Kostenaufwand verbunden. Der Einsatz einer hybriden Konstruktionsweise aus kohlenstofffaserverstärktem Kunststoff (CFK) und Mineralguss ermöglicht es...

The reaming process normally takes place at the end of manufacturing processes when a lot of value has already been added. Therefore, reaming plays an important role for the quality of the finished product. To achieve this high quality, the occurring process errors caused by the machine tool and the reamer or incorrect workpiece handling have to be...
