TL;DR: In this paper a systematic review of machine tool developments will be given and requirements on up to date machine tools will be worked out and some examples for potential future design ideas will be presented.
Abstract: Machine Tools are mother machines. They are necessary for the creation of any product. There is a correlation between machine tool capabilities and industrial achievements. The history shows that new innovative designs of machine tools led to remarkable technical as well as monetary results. Digitalization is changing our daily life in all aspects. A new “On demand economy” is coming up. No more an economy based on fixed plans is essential but an economy which is reactive to changes in daily life on time. Consequently also new production systems and machines are necessary for making it possible to adapt to new demands. This new era requires as well changes in machine tool design for taking benefit of the possibilities forwarded by digitalization. A paradigm change is necessary. In this paper a systematic review of machine tool developments will be given and requirements on up to date machine tools will be worked out. Finally, some examples for potential future design ideas will be presented.

TL;DR: In this paper , the authors developed a digital model of a lathe and related technology for its assembling, and a conceptual approach was proposed to design technological processes of lathe assembly with a wide range of technological capabilities.
Abstract: The article aims at developing a digital model of a lathe and the related technology for its assembling. The study is based on analyzing the service purpose and technological capabilities of modern modular machine tools, justification and development of the machine tool design according to the specified production conditions, and development of a technological process for assembling the proposed modular machine tool. The geometric modeling techniques and the design documentation were implemented to justify the rational choice of design parameters of the machine tool design and its spatial model. The proposed approach also considers structural elements and the relationships between them. As a result, a conceptual approach was proposed to design technological processes of lathe assembly with a wide range of technological capabilities. It allows implementation of the up-to-date strategy from idea to finished product at industrial enterprises. The practical significance of the obtained results for the machine-building industry is in the proposed practical recommendations for developing the technological process for assembling lathes.

TL;DR: Friedman and Friedman went to the same high school and used the Golden Arches Theory of Conflict Prevention as inspiration for his column "The GoldenArches theory of conflict prevention" as discussed by the authors.
Abstract: People always wonder, where does a talent like this come from? They ask, where does he come up with the inspiration for his columns and the titles for his books? Well, it just so happens that, in this case, I know I have insider information Tom Friedman and I went to the same high school, St Louis Park Senior High School, St Louis Park, Minnesota I know, for example, that there was a McDonald's directly across the street from our high school This first franchise McDonald's in America was the inspiration for his widely acclaimed column, "The Golden Arches Theory of Conflict Prevention"

TL;DR: In this paper, the authors discuss the challenges of managing product variety throughout the entire product life cycle, and the effective co-development of variants and their manufacturing systems to ensure economic sustainability.
Abstract: A great challenge facing industry today is managing variety throughout the entire products life cycle. Drivers of products variety, its benefits, pre-requisites and associated complexity and cost are presented. Enhancing consumers’ value through variety and approaches for achieving it efficiently including modularity, commonality and differentiation are discussed. Variant-oriented manufacturing systems paradigms, as enablers of product variety, and the effective co-development of variants and their manufacturing systems to ensure economic sustainability are reviewed. Industrial applications and guidelines to achieve economy of scope with advantages of economy of scale are discussed. Perspectives and insights on future research in this field are offered.

TL;DR: Abele et al. as mentioned in this paper described a method that considers the constructive particularities of the Reconfigurable Multitechnology Machine tool (RMM) taking flexibility aspects into consideration.
Abstract: Reconfigurable Manufacturing Systems (RMS) are characterized by their quick adaptation to un-scheduled and un-predictable changes in production requirements Trends, like the reduction of product life cycles, high products diversity at small lot sizes, as well as the fast development and implementation of new production technologies, call for new approaches in the design of flexible and life cycle overlappingmachine tools The flexibility of RMS comprises changes in machining technology, production capacity, machine structure and function as well as in work piece spectrum and material property The presented design of RMS is based on a construction kit principle, which enables it to adjust to new production requirements by substitution, addition or removal of machine systems A new trend in the area of RMS is the complete machining of work pieces by using different machining technologies in one machine workspace (Abele, Worn, 2004) This paper describes a method that considers the constructive particularities of the Reconfigurable Multitechnology Machine tool (RMM) taking flexibility aspects into consideration
