Twin-Control aims to develop a simulation system that integrates the different aspects that affect machine tool and machining performance, including lifecycle concepts, providing better estimation of machining performance than single featured simulation packages. This holistic simulation model will be linked to the real machines in order to update itself according to their real condition and to perform control actions that will lead to performance improvements.



Twin-Control presented at scientific-industrial forums

Before the summer, members of the Twin-Control consortium presented the project at different forums of sicentific-industrial interest.

  • NAFEMS World Conference 2017 took place in Stockholm, Sweden, 11-14 June 2017. Frédéric Cugnon from SAMTECH presented the paper “Machine tools mechatronic analysis in the scope of EU Twin-Control project”, co-authored by Mani Ghassempouri (COMAU) and Mikel Armendia (IK4-TEKNIKER). The main subject was machine tool FEM modelling and validation, using COMAU Urane machine as an example.

Monitoring infrastructure

A reliable and continuous monitoring of all use case machines is one of the most important task in Twin-Control. Overall, in Twin-Control six industrial use case machines (three at Renault, three at MASA), three laboratory use case machines (TU Darmstadt, TEKNIKER, ARTIS) and three Pilot-line use case machines (ETA Factory Darmstadt, Factory of the Future Sheffield, Basque AMC Bilbao) Read more

JIMTOF: A Strong Embrace of Industrial Internet of Things

Source: Modern Machine Shop Online

The message from the 2016 Japan International Machine Tool Fair (JIMTOF), Japan’s premier machine tool show, was clear: Japanese providers of manufacturing technology have embraced the concepts of the Industrial Internet of Things (IIoT). Although there is no exact definition for what this phrase means, it undoubtedly refers to the strategy of linking machine tools and other shopfloor equipment to a web-enabled network that makes manufacturing increasingly data-driven.


In fact, the Japanese Machine Tool Builders’ Association (JMTBA), the organization sponsoring JIMTOF, identified IIoT as the main component of this year’s show theme: “The Future Starts Here.” The IIoT capabilities of various machine builders in Japan were prominently displayed in booth exhibits. In general, these exhibits highlighted how data can be transformed into actionable information to avoid downtime and improve productivity through more thorough and timely monitoring.

The show also indicated that, for machine tool builders, the premier interoperability/data exchangeability standard is MTConnect, which is apparently being widely adopted to promote shopfloor connectivity. Significantly, a seminar on MTConnect was also presented at JIMTOF under the sponsorship of AMT—The Association For Manufacturing Technology. Attendance at this seminar indicated strong interest in the standard by both technology developers and end users.

Two Big Challenges

In addition to interoperability and data exchangeability, JIMTOF exhibitors are confronting two other major challenges in IIoT implementation: network security and effective data computing. One approach is to embed a configurable network switch inside a machine’s CNC to manage network exposure internally. The other approach is to “bolt on” an external device that incorporates the network switch and forms the secure interface to the network.


The challenge of effective data computing boils down to a very practical matter. Because the flow of data from connected machines can be voluminous, managing when, where and how to process this data is critical. Although cloud-based applications can bring to bear virtually unlimited computer power to the tasks of collecting, analyzing and storing vast amounts of data, deriving and delivering actionable intelligence to the shop floor in a timely fashion is a problem. It is eliciting an alternative concept—that of “edge” computing or computing in the “fog.” The principle is to conduct data computing and analysis with resources shared within a corporate network, but away from a centralized capability such as a cluster of servers in one location. Edge computing is an advantage because, for one, it avoids traffic jams on the data highway, so to speak, which can delay results when computing is done remotely.

Other Noteworthy Trends

Hybrid machines that combine subtractive processes (conventional milling, grinding, turning and so on) with additive processes (laser cladding, wire arc welding, laser metal deposition) were notable. The Japanese government is providing substantial funding for research in hybrid technology, and this showing reflects that support.

Additionally, several builders have incorporated collision-avoidance features into the software in the CNC. Essentially, the simulation of the machining program stays ahead of its actual execution, creating an opportunity for the software to detect and avoid impending crashes or interference.


Another frontier that machine tool builders are pushing into is machining accuracy in the sub-micron level. Applications range from miniaturized electronics to advanced designs of airspace components such as jet engine blades.

Finally, it should be noted that JIMTOF 2016 marked the opening of two new exhibit halls, thereby increasing exhibit space to nearly 100,000 square meters. The new halls, East 7 and 8, were dedicated largely to overseas exhibitors who have been closed out of this show in the past because of strong participation by domestic exhibitors. These additions enhance JIMTOF’s reputation as a major international machine tool and manufacturing technology show.

DMG-Mori and Schaeffler towards Industry 4.0

Source: DMG Mori

Last year, DMG MORI presented an Industry 4.0 project developed in collaboration with its technology partners. Based on the DMC 80 FD duoBLOCK®, DMG MORI presented a machine tool equipped with more than 60 sensors that transmitted digitised information on components from the sensors to the cloud for the purposes of data collection, storage and analysis. The objective was constant status monitoring within the machine. The app-based control and operating system CELOS® supports the interaction between human and machine.

This generates benefits for users in two ways. The Condition Analyzer visualises the process parameters in CELOS®, allowing prompt power and status analyses to be carried out on the machine. Additionally, the recorded data are compiled within a cloud architecture and analysed with special algorithms.

Schaeffler Technologies in Höchstadt an der Aisch is working out how to convert the data into practical machining knowledge. A DMG MORI pilot machine has been in ongoing operation there since late October 2015. Schaeffler considered the opportunities highly diverse. They range from better management of the machining process, e.g. in order to focus more on tool wear, to lower energy or lubricant consumption. Likewise, on the basis of empirically determined ‘behaviour patterns’, the transferred status data can be used to make qualified predictions about potential damage to the spindle.


The first step has been taken towards the future of machining and the results are very promising. However, it is still too early for a definitive evaluation. However, Schaeffler expects to produce valid findings before the end of the year. ‘The important thing is that we have started and will gradually learn how Industry 4.0 works in practice from a real production facility’, says Martin Schreiber, Head of Production Machines at Schaeffler Technologies AG & Co. KG.
