“…Brankamp and Herrmann [32] introduced the idea of Building Block Systems (BBS), which was intensively studied by Ito [33] with respect to modularized machine tools. Wulfsberg et al [34] summarize different concepts of machine tool modularity in micro-production and present solutions for the scalability of the working area. Mori and Fujishima [31] designed a reconfigurable machine tool with axis modules that allow the spindle configuration to be changed between horizontal and vertical.…”

Machine tools are the main driver of economic, environmental and social sustainability in industrial production. The ongoing shift from mass production to highly individualized, small batch manufacturing requires machine tools to be more flexible to changing needs while maintaining at least the same level of productivity. However, flexibility and productivity are at odds with the necessity for resource and energy efficiency. At the same time, more sophisticated workpiece specifications are pushing the boundaries regarding precision and dynamics of machine tools. In such a high-performance context, machine safety plays a major role and is becoming increasingly challenging due to higher kinetic energies of moving components. This paper examines recent advances in machine tool precision, sustainability, and safety. Six comprehensive case studies are provided to illustrate how these improvements contribute to an increased productivity. Hardware and software solutions for pose-controlled robotic manufacturing and thermoelectrically tempered high-performance spindles will be presented. Modular machine tool frames based on building blocks and an adaptive cooling system with thermoelectric generators for linear direct drives demonstrate their major impact on resource and energy efficiency. Machine safety is addressed through an analysis of potential hazards as well as improved protective measures. Model-based predictions precisely identify critical process parameters that lead to unbalance-induced failure of slim tool extensions, while on the protection side, new statistical models are applied to assess the protective performance of safeguards much more accurately. The cutting-edge technologies for machine tools presented in this paper will help manufacturers to cope with current and future challenges in industrial production.

“…The design of the machine tools allowed for selecting a number of axes by the individual axis modules and reconfiguration of the spindle in horizontal and vertical directions. Wulfsberg et al (2013) give a summary of the concepts developed in the context of modularity in small machine tools for micro-production. The design measures are associated with those of conventional machine tool components for the development of modular systems.…”

Environmental, economic and social changes of any significant proportions cannot take place without a major shift in the manufacturing sector. In today's manufacturing processes, economic efficiency is realised through high volumes with the use of specialised machine tools. Change in society, such as in the form of mobility and digitisation, requires a complete overhaul in terms of thinking in the manufacturing industry. Moreover, the manufacturing industry contributes over 19 % to the world's greenhouse gas emissions. As a consequence of these issues, a demand for sustainable solutions in the production industry is increasing. In particular, the concept of "cost" in manufacturing processes and thus the "system boundaries" within the production of the future has to be changed. That is, a great number of aspects to the machine tool and production technology industries can be improved upon in order to achieve a more sustainable production environment. Within this chapter, the focus lies on microsystem technology enhanced modular machine tool frames, adaptive mechatronic components, as well as on internallycooled cutting tools. An innovative machine tool concept has been developed recently, featuring a modular machine tool frame using microsystem technology for communication within the frame, which allows for a high level of flexibility. Furthermore, add-on upgrading systems for outdated machine tools-which are particularly relevant for developing and emerging countries-are poised to gain in importance in the upcoming years. The system described here enables the accuracy of outdated machine tools to be increased, thus making these machine tools comparable to modern machine tool systems. Finally, the cutting process requires solutions for dry machining, as the use of cooling lubricants is environmentally damaging and a significant cost contributor in machining processes. One such solution is the use of internally cooled cutting tools.

Increasing social and economic imbalances as well as restricted access to production means and participation in value creation processes ask for new approaches to overcome the asymmetric distribution of knowledge and information between producers and consumers as well as between industrialized and developing countries. Technical progress in production technology, the advancement and spread of information and communication technologies (ICT) as well as the spill-over of the highly efficient and innovative open source principles to the world of physical products represent a new set of tools and concepts to address this challenge. Correspondingly, we can observe (new) modes of value creation that put into question traditional economic strategies and assumptions by stressing collaboration instead of competition and knowledge sharing instead of black box engineering.The FabLab movement (fabrication laboratory) is one emerging and promising approach for decentralized, participative, locally grounded and globally interconnected value creation. This paper presents findings from a study on the latest development, effects and success of FabLabs focusing especially on its potential for development cooperation. Based on findings from the survey and the premises of the FabLab idea, we finally present the multidisciplinary OpenLabs concept.
