Elektrisches Spannfutter für die Drehbearbeitung/Electric chuck for turning – Electric chuck with high-precision clamping force control for thin-walled workpieces
Authors: Wnendt Eike , Denkena Berend , Klemme Heinrich , Meier Matthias 
Published: September 2022

Eine Herausforderung beim Spannen dünnwandiger Werkstücke stellt die Fertigung engtolerierter Werkstücke dar. Aufgrund der geringen Steifigkeit dünnwandiger Werkstücke können durch zu hoch eingestellte Spannkräfte unzulässig hohe Maß- und Formabweichungen auftreten. Zusammen mit der HWR Spanntechnik GmbH erforscht das Institut für Fertigungstechnik und Werkzeugmaschinen (IFW) der Leibniz Universität Hannover daher ein neuartiges sensorisches Spannfutter zur präzisen Spannkrafteinstellung.

Clamping thin-walled workpieces is a challenging problem in high precision turning. Due to the low stiffness of thin-walled workpieces, high workpiece deformations can occur when clamping forces are set too high. For this reason, a sensory chuck for precise clamping force adjustment is being researched by HWR Spanntechnik GmbH and the Institute of Production Engineering and Machine Tools (IFW) at Leibniz Universität Hannover.

Published: September 2022

Handhabungsprozesse sind Teil nahezu jedes automatisierten Prozesses. Während das Handhabungsgerät verhältnismäßig einfach an neue Handhabungsaufgaben angepasst werden kann, erfolgt die Gestaltung der Greiferfinger als Schnittstelle zwischen Handhabungssystem und Objekt meist händisch und basierend auf Erfahrungswissen. Dieser Beitrag beschreibt die Entwicklung eines Greiferfingerbaukastens, der für eine automatisierte Konfiguration anwendungsspezifischer Greiferfinger genutzt werden kann.

Handling processes are part of almost every automated process. While the handling device is relatively easy to adapt to new handling tasks, the design of the gripper fingers as the interface between handling system and object is usually done manually, based on empirical knowledge. This paper describes the development of a gripper finger construction kit to automate the configuration of application-specific gripper fingers.

Dieser Beitrag stellt ein Konzept für die Integration von interaktiven Simulationsmodellen in einer Virtual-Reality (VR)-Simulationsumgebung vor. Dabei werden die Simulationsmodelle aus der virtuellen Inbetriebnahme (VIBN) von Produktionsanlagen betrachtet. Ein Ziel der erweiterten VIBN mithilfe von einer VR besteht darin, die Lücke zwischen VIBN und der realen Inbetriebnahme zu schließen. Damit das vorhandene VIBN-Modell möglichst einfach in der VR-Visualisierung integriert werden kann, ist es essenziell, eine Durchgängigkeit des Simulationsmodells im Engineering zu gewährleisten. Aus diesem Grund wird auf das bestehende Austauschdatenformat „AutomationML“ eingegangen.

This paper presents a method for integrating interactive simulation models into a virtual reality (VR) simulation environment. To this end, simulation models from virtual commissioning (VIBN) of production plants are considered. One goal of enhanced VIBN using VR is to close the gap between VIBN and real commissioning. To integrate the existing VIBN model as easily as possible into the VR visualization, it is essential to ensure engineering continuity for the simulation model. For this reason, the existing exchange data format AutomationML will be discussed.

AR-Assistenz für die modulare Spannmittelmontage/Error-free Assembly of Clamping Systems – Assembly Assistance for Modular Clamping Systems
Authors: Sauer Steffen , Berndt Dirk 
Published: September 2022

In der CNC-Bearbeitung ist es zur Kollisionsvermeidung sehr wichtig, dass real aufgebaute Spannsysteme exakt der Vorgabe aus der CAD/CAM-Simulation entsprechen. In diesem Beitrag wird ein industrietaugliches Assistenzsystem präsentiert, mit dem per Augmented Reality (AR) die manuelle Montage von modularen Spannsystemen unterstützt wird und so Fehler vermieden werden können. Es wird aufgezeigt, dass die Kamera-Monitor-basierte AR geeignet ist, um unter rauen Bedingungen intuitive Montageanleitungen zu visualisieren. Dadurch lassen sich Bearbeitungszeiten in der CNC-Maschine verkürzen und die Montage beschleunigen.

In CNC machining, the similarity of real assembled clamping systems compared to the constructed clampings in CAD/CAM is of critical importance. If differences are present, unintentional collisions between tool and clamping system can occur, which may lead to total breakdown. In this work we present an Augmented Reality (AR) industry-ready assistance solution, which helps workers to reduce the error rate when clamping systems are assembled manually. We will show that camera-screen-based AR is well suited to present assembly instructions in harsh environmental conditions and that by using this solution machining times can be reduced and the assembly itself can be accelerated significantly.

El territorio Awa comprende 121.000 ha, y se encuentra representado por la Federación de Centros Awa del Ecuador (FCAE). La Federación ha asumido la administración de los recursos naturales presentes en su territorio; por tal razón, ha perfeccionado un Programa para el Manejo Forestal Sostenible (PMFS) dentro de su área. El objetivo fue establecer el potencial forestal desde el punto de vista social, económico y productivo de los territorios seleccionados para ser manejados por los indígenas. El Territorio Awa está ubicado en el extremo noroccidental del país, en las estribaciones occidentales de los Andes, desde 80 a 1.600 m.s.n.m. El estudio incluyó: Planificación, Zonificación preliminar, Evaluación de la capacidad social, Evaluación de la capacidad productiva. La FCAE cuenta con información del recurso forestal y es la organización indígena más consolidada a nivel nacional, pueden reconocer sus debilidades y amenazas, desde el punto de vista forestal, esto es una ventaja para continuar mejorando el manejo del bosque. El territorio Awa, constituye en la actualidad el último remanente significativo de la especie forestal Chanul (Humiriastrum procerum) en Ecuador.
Según inventarios forestales, la abundancia de la especie es irregular, hay sitios que, por sus condiciones edafoclimáticas propias, presentan mayor abundancia de la especie, por tanto, no se puede generalizar estos datos en todo el territorio Awa, ya que existen otros sitios con poca abundancia. Se concluye que esta área de la población Awa al estar ubicada en la frontera noroccidental del país y disponer de un potencial forestal importante, el estado debería apoyar al uso, aprovechamiento y conservación del territorio.

Published: September 2022

In recent years, the use of solar systems has been increasing worldwide in an accelerated rate, with perspective of staying among the main sources of renewable energy for the following decades, along with wind power. The photovoltaic energy in Brazil currently represents 4,5 GW (2,5% of the national electric matrix). Solar thermal energy is called when solar radiation is used to transfer energy to a medium, usually water or air. It is a renewable, sustainable and environmentally friendly source of energy. The number of solar thermal energy applications is very extensive when considering all temperature levels and energy demands. In this context, the present work shows the evolution of solar photovoltaic energy in Brazil, bringing a discussion regarding to solar power characteristics, working principles and different technologies of solar cells, as well as aspects of operation and maintenance of the photovoltaic panels. Investments in research for the development of new technologies and valuation of existing ones for solar energy should also be prioritized, as well as for better planning and sustainable use of photovoltaic energy, given the advantages for the economy, society and the environment provided by this renewable and clean source.
Introduction
Authors: Schober Adrian 
Published: September 2022

The release of The Omen on the sixth day of the sixth month 1976 marked the year of the Devil, at least according to 20th Century Fox’s publicity campaign. It was a film that fed a seemingly insatiable appetite for Devil-inspired movies, gaining much from mounting fears about the so-called crisis in mainstream Christianity, the spread of Satanism and cults, and the end times. It also cynically tapped into the growing fear of corruption and conspiracy in American politics and government in the 1970s. For this reason, it ought to be included in the same company as other ‘paranoid’ movies of the period, including The Conversation, Three Days of the Condor, All the President’s Men and Marathon Man. This introduction covers the genesis, authorship, production history, elaborate marketing and polarised reception of The Omen.

Introduction: Timely and appropriate management of snakebites in the tropics is a lifesaver. Many snakebite patients are being bitten in remote rural areas and do not manage to get in due time to healthcare facilities. This study assessed the clinical features and the risk factors associated with treatment outcomes of snakebite patients admitted at two hospitals in the Northwest of Ethiopia.
Methodology: In a retrospective cohort study, routinely collected data from 250 patients’ medical charts at University of Gondar Hospital and Metema Hospital, between September 2012 and August 2020, were reviewed.
Results: The median age of the snakebite cases was 24 years (95% CI = 22-26), with 80.8% male patients. At admission 148/250 patients presented in Clinical stage 1 or 2 (local symptoms only) and 73.7% presented more than 12 hours after the bite, 80.2% received antibiotics and 79.0% antivenom. The median duration of hospitalization was 3 days (95% CI = 3-4); 72% of the patients recovered and were discharged, 10.8% died and 0.5% underwent an amputation. On logistic regression analysis, residence in rural areas (AOR = 2.52, 95 % CI = 1.2-5.3), sign of bacterial superinfection on the bite site (AOR = 4.69. 95% CI = 1.4-15.4), clinical stage 3 or 4 with systemic symptoms or toxic signs at admission (AOR = 4.84, 95% CI = 1.3-18.0) and no treatment with antivenoms (AOR = 6.65, 95% CI = 1.6-27.7) were associated with bad outcome (death, amputation and/or referred/ went against medical advice).
Conclusions: Timely presentation at early clinical stage, appropriate clinical management and availability of antivenoms are cornerstones to reduce snakebite morbidity and mortality.

Introduction: While ivermectin mass drug administration (MDA) has been implemented since long for onchocerciasis elimination, there is doubt whether this would also be effective for scabies control. If effective, this would allow integration of both programs. We compared scabies prevalence in districts implementing ivermectin MDA for the onchocerciasis elimination program and those not implementing the intervention in Amhara region, Ethiopia.
Methodology: We conducted a cross-sectional study comparing the scabies prevalence in 14 districts implementing ivermectin MDA for onchocerciasis elimination program between 2013-2018 and in 28 districts without this intervention in Amhara region Ethiopia. We used 2018 scabies survey data to determine scabies prevalence. All individuals screened for scabies during the survey were included. We collected data on risk factors from the districts database and annual reports. Multivariate linear regression analysis was used to account for potential confounding factors.
Results: We included data on 4,319,064 subjects across 42 districts. Except the differences in temperature and population density, districts in both groups were comparable. A total of 371,780 scabies cases were detected in the 2018 survey. The median scabies prevalence was 6% (IQR 2.6-11.9) in the intervention districts and 5.2% (1.8-10.4) in the control districts (p-value 0.77). In adjusted analysis, the difference remained statistically non-significant (coefficient 0.37 (95% confidence interval (-0.93-1.67); p-value 0.554).
Conclusions: The implementation of ivermectin MDA for onchocerciasis control was not associated with reduced scabies prevalence. Consequently, standard scabies MDA should be deployed for scabies control.
