Process types of customisation and personalisation in design for additive manufacturing applied to vascular models

Johanna Spallek & Dieter Krause
Manufacturing companies face high demand for products that fulfil individual customer desires. Recent improvements in additive manufacturing (AM) enable the fabrication of customer-specific components of a product. This paper presents a categorisation of design processes for customised and personalised products through the use of AM in three process types: special design, specific adaptation, and standardised individualisation. The characteristics of design processes are examined in medical development of vascular models integrated into a modular neurovascular training...

Analysis of design guidelines for automated order acceptance in additive manufacturing

Jan-Peer Rudolph & Claus Emmelmann
Additive manufacturing (AM) is increasingly used in industrial production. Compared to conventional manufacturing technologies, such as milling and casting, AM offers a high degree of design freedom. Nevertheless, still some manufacturing restrictions and design guidelines have to be considered to ensure a flawless production. Therefore, a checking of design guidelines is a necessary step in order acceptance. Addressing this need, this paper presents an integrated analysis of design guidelines for an automated order acceptance. In...

Analysis and Modeling of Heat Flux into the Tool in Abrasive Circular Cutting of Unidirectional CFRP

Wolfgang Hintze & Christian Klingelhöller
For edge trimming of slightly curved thin walled CFRP parts dry circular cutting is a promising alternative. However, a high fraction of the cutting energy is converted into heat. The study focuses on the determination of the amount of heat dissipated by the tool in circular cutting of unidirectional CFRP with epoxy matrix. An inverse heat conduction model is developed and solved for a set of temperature profiles measured on the tool surface with an...

Influence of curved workpiece contours on delamination during end milling of FRP

Wolfgang Hintze & Felix Brügmann
When end milling long fiber reinforced composites, fiber protrusions of the top layers can occur. The lengths of fiber protrusions found on real workpieces with curved contours cannot be explained so far. The lengths of individual fibers to be cut along the tool path depend on tool diameter, local fiber orientation and path geometry. All fibers are separated into two ends at the initial contact with the tool. They define the theoretical maximum lengths of...

Towards a decision-making framework for multi-criteria product modularization in cooperative environments

Marc Windheim, Nicolas Gebhardt & Dieter Krause
Modular product family design is a strong strategy to offer a wide range of product variants economically. Many methods for designing and assessing modular product concepts are provided in literature - deciding between modular product structure alternatives, however, is still a challenging task, because of the many and unforeseeable effects on all product life-phases in combination with the high number of involved stakeholders. In addition, modularity alternatives cause multi-dimensional trade-offs that make the decision process...
