Today, the micro-factory concept of downsizing production systems is essential to manufacturing small products in sustainable growth. Concerning this, this paper presents the developments accomplished during the recent years at Tecnológico de Monterrey (Mexico) and Holguin University (Cuba) introducing new findings related to the design of reconfigurable micro-factories based-on micro-machine tools. The chapter discusses the proposed framework for the optimizing the development of micro-factories in the context of micro-reconfigurable manufacturing systems based-on micro-reconfigurable machine tools. The novel methodology for optimizing the scheduling of reconfigurable micro-factories were exposed and a scheduling optimization of a reconfigurable micro-factory prototype was designed and tested.

Micro Machine Tool

Since micro products have become smaller, the requirements concerning precision and accuracy for producing machine tools to manufacture such small parts increased. Consequently, each component of a machine tool needs to conform to these requirements. A flexure-based feed unit, a clamping system and mechanical couplings are briefly presented. These components can quickly be reconfigured, which allows for a new modular micro machine tool system. Each component incorporates individual precision and accuracy leading to an overall error budget for a machine tool system. This is methodically addressed in the contribution.

Neuer Markt

Mit der Etablierung von kleinen Bearbeitungsmaschinen im Bereich der dentalen Technologie wurde ein neuer Markt und Anwenderkreis für die Nutzung von automatisierter Fertigungstechnik erschlossen. Der zunehmende Einsatz sogenannter Rapid-Manufacturing-Technologien wird neben oder gerade aufgrund additiver Verfahren weiterhin auch den Einsatz von Kleinstbearbeitungsmaschinen (abtragend oder Hybridmaschinensysteme) auf und abseits des industriellen Fertigungsumfeldes fördern. Die Untersuchung der Maschinenpräzision bedeutet aufgrund des geringen Bearbeitungsraumes eine große Herausforderung an die eingesetzten direkten und indirekten Messverfahren.   With the establishment of small machine tools in dental technology, a new market and user community have been developed for the use of automated manufacturing technology. The increasing use of so-called rapid manufacturing technologies will further the use of micro machine tools among or because of additive processes in and around the industrial production environment. The examination of machining quality and machine precision is a major challenge for the direct and indirect measurement methods being used because of the limited working space of micro machine tools.

This paper presents the investigation of minimum recast layer of zirconium oxide (ZrO2) due to micro-EDM using EDM-3 synthetic oil as dielectric fluid and tungsten as the tool electrode with control parameters of rotational speed and gap voltage. The investigation was performed using multi-process micro machine tools DT 110. The recast layer thickness was observed using scanning electron microscope and its hardness was measured using micro-Vickers hardness tester. The hardness data were analyzed and an empirical model was developed. The optimum value for minimum recast layer hardness was 873.46 Hv with rotational speed of 395 rpm and gap voltage of 110 V.
