Components for furniture production, particularly in the industrial sector, are usually manufactured in automated process chains. State- of-the-art for drilling is the usage of systems with bevels, belt drives, angle gears and rigid drilling units. Due to the operating direction and slow working cycles, drilling processes are the bottleneck of production. These rigid drilling gears are currently very intensive in maintenance and inflexible because their spindles are usually mechanically coupled , which leads to unnecessary and excessive energy consumption. Another problem with systems currently in use is the huge amount of setup costs. They are required to adjust drilling units on different components. This leads to an impairment of productivity of the entire manufacturing process. At this point the question arises how quality and efficiency of the drilling process can be increased. lt is obvious that the drilling process must be made more intelligent and more flexible. An approach for an optimized drilling process is the use of self-optimizing spindles in future. Therefore a detailed analysis of drilling processes and the development of an eligible feed control are required. According to these requirements a laboratory machine was developed and furthermore the theoretical and practical state-of-the-art of drilling processes were analyzed. To develop a self-optimization for drilling spindles a research project is currently being realized in cooperation between the Laboratory for Woodworking Technologies and Machinery (HS-OWL, Germany)), the Laboratory for Power Electronics and Electrical Drives (HS-OWL, Germany) and the Wittenstein motion control GmbH (Bad Pyrrnont, Germany).}}, author = {{Bursch, Dennis and Riegel, Adrian and Borcherding, Holger and Akemeier, Volker}}, booktitle = {{Production engineering and management proceedings 3rd international conference 26th and 27th September 2013 Trieste, Italy}}, editor = {{Padoano, Elio and Villmer, Franz-Josef}}, isbn = {{978-3-941645-09-7}}, location = {{Trieste, Italy}}, number = {{3}}, pages = {{91 -- 102}}, publisher = {{Hochschule Ostwestfalen-Lippe, Fachbereich Produktion und Wirtschaft}}, title = {{{INTELLIGENT DRILLING- DIRECT-DRIVEN, SELFOPTIMIZING HIGH-SPEED DRILLING SPINDLES FOR FURNITURE INDUSTRY}}}, volume = {{9}}, year = {{2014}}, } @inproceedings{247, author = {{Austermann, Johann and Borcherding, Holger and Böcker, J.}}, booktitle = {{Proceedings / PCIM Europe / International Exhibition and Conference for Power Electronics, Intelligent Motion Renewable Energy and Energy Management, Nuremberg, 14 - 16 May 2013.

A model-based approach with a timed hybrid automaton as overall system model is employed for anomaly detection. The approach is based on the assumption of several system modes, i.e. phases with continuous system behavior. Transitions between the modes are attributed to discrete control events such as on/off signals. The underlying discrete event system which comprises both system modes and transitions is modeled as finite state machine. The focus of this paper is set on the modeling of the energy consumption in the particular system modes. Sequences of stochastic state space models are employed for this purpose. Model learning and anomaly detection for this approach are considered. The proposed approach is further evaluated in a small model factory. The experimental results show significant improvements compared to existing approaches to anomaly detection in hybrid industrial systems.}}, author = {{Windmann, Stefan and Jiao, Shuo and Niggemann, Oliver and Borcherding, Holger}}, booktitle = {{11th International IEEE Conference on Industrial Informatics}}, location = {{Bochum}}, pages = {{194 -- 199}}, publisher = {{IEEE}}, title = {{{A Stochastic Method for the Detection of Anomalous Energy Consumption in Hybrid Industrial Systems}}}, year = {{2013}}, } @inproceedings{4896, author = {{Austermann, Johann and Borcherding, Holger and Böcker, J.}}, booktitle = {{Proceedings / PCIM Europe / International Exhibition and Conference for Power Electronics, Intelligent Motion Renewable Energy and Energy Management, Nuremberg, 14 - 16 May 2013.

Limits for the frequency range from 2 kHz to 9 kHz are in discussion. Because of this mentioned gap in the standards there is an uncertainty how to design filters and disturbance sources like converters. For finding limits investigations are necessary on mains impedances and harmonics. There are older publications on mains impedances (e. g. [4], [5]), but they include only measurements of impedances between one phase and neutral conductor and no measurements of impedances between the phases. This is important for three-phase loads. Furthermore in [4] no measurements were made in industrial mains and the investigations were carried out more than one decade ago. Especiaily in the last years the electrical environment in the mains has changed because of the increasing number of self-commutated converters. Accordingly, much higher amplitudes for harmonics in the upper frequency range are identifiable. In this paper current investigations on mains impedances and harmonics are presented which were carried out in universities, companies and private houses. The results could be used as a base for finding limits and for designing filters and disturbance sources economicaily.}}, author = {{Borcherding, Holger and Balzer, Eugen and Garbe, Heyno}}, booktitle = {{Proceedings - PCIM Europe 2010}}, isbn = {{978-3-8007-3229-6}}, location = {{Exhibition Centre Nuremberg}}, pages = {{631 -- 635}}, title = {{{Measurements of mains impedances in the frequency range up to 20 kHz and analysis of harmonics up to 10kHz in low voltage mains}}}, year = {{2010}}, } @book{4215, author = {{Nerreter, Wolfgang and Flegel, Georg and Birnstiel, Karl and Borcherding, Holger and Meier, Uwe}}, isbn = {{978-3-446-41906-3}}, pages = {{347}}, publisher = {{Carl Hanser Verlag}}, title = {{{Elektrotechnik für Maschinenbau und Mechatronik}}}, year = {{2009}}, } @inproceedings{4216, author = {{Borcherding, Holger}}, booktitle = {{Internationaler ETG-Kongress 2009 (ETG-FB 118) : Fachtagung 1: Intelligente Netze / Fachtagung 2: Leistungselektronik in Netzen}}, editor = {{Kreusel, J.}}, isbn = {{978-3-8007-3194-7}}, location = {{Düsseldorf}}, pages = {{399 -- 402}}, publisher = {{VDE-Verlag}}, title = {{{Über den Inhalt der IEC 62578 DTS: Technical Specification: Operations and Characteristics of activeinfeed converter applications}}}, year = {{2009}}, } @inproceedings{4217, author = {{Borcherding, Holger and Teisch, Arthur and Obernolte, Urs}}, booktitle = {{Internationaler ETG-Kongress 2009 (ETG-FB 119) : Fachtagung 3: Direktantriebe in Produktionsmaschinen und Industrieanlagen - Generatoren und Antriebe in regenerativen Kraftwerken / Fachtagung 4: Diagnostik elektrischer Betriebsmittel}}, isbn = {{978-3-8007-3195-4}}, location = {{Düsseldorf}}, pages = {{103 -- 108}}, publisher = {{VDE-Verlag}}, title = {{{Verbesserte Energieeffizienz durch direktangetriebene winkelgeberlose drehzahlgeregelte Spindeln bei Mehrachsbohrköpfen für die holzverarbeitende Industrie}}}, year = {{2009}}, } @inproceedings{4291, author = {{Borcherding, Holger}}, location = {{Düsseldorf}}, title = {{{Technical Specification: Operations and Characteristics of active infeed converter application}}}, year = {{2009}}, } @misc{4231, author = {{Borcherding, Holger}}, title = {{{Verfahren zur Temperaturüberwachung eines Elektromotors}}}, year = {{2003}}, } @misc{4237, author = {{Borcherding, Holger}}, title = {{{Kühlkörper für einen Frequenzumrichter}}}, year = {{2002}}, } @book{4210, author = {{Borcherding, Holger}}, isbn = {{3-89720-376-6}}, pages = {{117}}, publisher = {{Papierflieger Verl.}}, title = {{{Eigenschaften von Netzpulsstromrichtern mit eingeprägter Gleichspannung}}}, year = {{1999}}, }
