Doreth, K., Henjes, J., Kröning, S.: (2013): Approach to forecast energy consumption of machine Tools within the design phase, WGP Kongress 2013, 22.+23.07.2013, Erlangen, 7 S. | Datei | Beschreibung: For environmental and economic reasons, energy- and resource- efficient operations of cutting machines are increasingly important. The determination of properties and functions of machine tools, which affect future energy consumption in operation, essentially takes place within the design phase by combining required components. Therefore, it is necessary to develop approaches to find an efficient optimum between energy consumption, productivity, acquisition costs and operating costs within the design phase of a machine tool. However, the energy consumption of a machine tool depends on the application scenario. In addition to that, it is difficult to forecast the energy consumption of several components because of their mutual interaction. Existing approaches to forecast the energy consumption of a machine tool within design phase are based on complex simulation or mathematical models which are difficult to parameterize for the design of a machine tool and thus, for the comparison of various configuration alternatives. An alternative for forecasting energy consumption is the use of empirical information. That Information can be acquired by measuring the energy consumption of machine tools in operating production systems. This paper presents an approach to forecast the energy consumption of machine Tools within the design phase, which will be developed by the Institute of Production Engineering and Machine Tools. It will be based on the data feedback (empirical information) from a machine tool operating in an existing manufacturing system. For this purpose, a logger module will be developed, which continually captures the energy consumption by means of the machine integrated sensors. That information will be sent back to an energy navigator module, which processes that information in order to forecast the energy consumption of a new designed machine tool. Also, the lifecycle costs will be calculated in order to rate cost and benefits of each machines lifecycle in terms of energy consumption.

Denkena, B., Kröning, S.: (2013): Dynamic scheduling of maintenance measures in complex production systems, CIRP Journal of Manufacturing Science and Technology, Volume 6, Issue 4, 2013, S. 292–300. | Datei | Beschreibung: In complex production systems, involving multiple, mutually dependent process steps, the unplanned failure of even a single machine can have significant consequences (e.g. loss of production) for upstream and downstream process steps and equipment. In order to detect maintenance needs before the machine components fail, condition monitoring systems are increasingly applied in practice. However, the main requirement for short-term scheduling of planned maintenance measures is to predict the impact of the ensuing downtime of the machine on the productivity of the whole production system. This is hardly possible for the production planner due to the dynamic and stochastic interactions (e.g. variation of buffer levels over time) of production processes. As a consequence, high production and maintenance costs tend to occur. Hence, a model-based planning approach which enables the dynamic short-term scheduling of planned maintenance measures has been developed. Instead of focusing separately on production and maintenance, this integrated approach allows a forecasting of the most cost-effective period of necessary maintenance measures for machines which are part of a complex production system. In contrast to existing, static approaches which fail at accurately representing the dynamic of production states and information, this approach aims to determine the various failure-related costs and to evaluate the impact of the maintenance measures on the production processes by means of event-driven simulation. The prediction accuracy is ensured by integrating the dynamic and stochastic correlations characteristic of real production systems into the simulation model. A concluding evaluation of the approach based on real application scenarios of an industrial company illustrates the need for a dynamic planning to lastingly reduce the production and maintenance costs of production systems compared to a purely static evaluation and planning based on average values (e.g. for transport time).
