They supply the necessary flexibility for smart factories which produce individualized products with lot sizes down to one. With the increased number of tasks for automated guided vehicles, the requirements for their wireless communication systems become more demanding and current solutions won&#x2019;t be sufficient anymore. To efficiently develop, configure and setup communication systems, the knowledge about what type of information is communicated and what are the characteristics of the information communicated is necessary. This work identifies most relevant types of information in an automated guided vehicle system based on a set of use-cases. For each identified information type, an estimate for the communication properties (payload size, cycle-time and latency) is given. The information types are then classified into traffic types for further use to design a wireless communication system.}, author = {Neher, Philipp and Lechler, Armin and Verl, Alexander}, booktitle = {2022 8th International Conference on Automation, Robotics and Applications (ICARA)}, doi = {10.1109/ICARA55094.2022.9738572}, eventdate = {18.02.2022-20.02.2022}, isbn = {9781665483834}, issn = {2767-7745}, language = {en}, month = {02}, pages = {68-75}, publisher = {Institute of Electrical and Electronics Engineers Inc.}, title = {Identification and Classification of the Communication Data of Automated Guided Vehicles and Autonomous Mobile Robots}, url = {http://www.icara.us/2022.html}, venue = {Virtual, Online, Czech republic}, year = 2022 }

  @inproceedings{9734108, abstract = {The demand for highly customized products will be met in the future by smart and flexible factories. Future factories will rise to this challenge by employing stationary and mobile Cyber Physical Systems (CPS) which need to exchange various information. With mobile systems, this should be done wirelessly. This paper evaluates a previously proposed concept for a deterministic wireless communication system based on LTE. The concept combines LTE for data transmission with GPS for time synchronization and a time-based control scheme to enable a deterministic exchange of control information. To conduct experimental evaluation, an implementation of the concept is necessary. A prototypical implementation using off-the-shelf hardware and custom software is presented. Using two exemplary test cases, the concept and implementation are evaluated with regard to the overall system latency and the quality of the time synchronization of the internal clocks. The level of synchronicity of coordinated output values after transmitting the corresponding set-point values over the communication system is evaluated in another exemplary test case using a total of three communication end devices. With a measured maximum offset of 814 &#x00B5;s between the synchronized output of two receivers, the concept and implementation stand validated and deemed feasible.}, author = {Neher, Philipp and Lechler, Armin and Verl, Alexander}, booktitle = {2022 8th International Conference on Mechatronics and Robotics Engineering (ICMRE)}, doi = {10.1109/ICMRE54455.2022.9734108}, eventdate = {10.02.2022-12.02.2022}, isbn = {9781665483773}, language = {English}, month = {02}, pages = {157-162}, publisher = {Institute of Electrical and Electronics Engineers Inc.}, title = {Experimental Evaluation of the Deterministic Wireless Communication System Industrial LTE}, url = {http://icmre.org/}, venue = {Virtual, Munich, Germany}, year = 2022 }

Therefore, the performance impact of software-based fault-tolerance methods is challenging. Using software-based fault tolerance is an attractive approach because commercial off-the-shelf hardware can be used. One possibility to implement software-based fault tolerance are arithmetic codes, already used in safety-critical products. Recently, AN codes have received particular attention; however, they have a significant performance impact in complex safety applications that require 64-bit wide integer calculations. Therefore, we comprehensively analyze different arithmetic codes in this work to identify the best suitable 64-bit integer support. We identify the ones' complement as the best matching encoding strategy through new code metrics, fault simulations, and performance analysis. We validate our results by applying ones' complement coding to a sample algorithm. Performance measurements and fault injection simulation confirm our results.}, address = {Cham}, author = {Fischer, Marc and Riedel, Oliver and Lechler, Armin}, booktitle = {Computer Safety, Reliability, and Security}, doi = {10.1007/978-3-031-14835-4_10}, editor = {Trapp, Mario and Saglietti, Francesca and Spisl{\"a}nder, Marc and Bitsch, Friedemann}, isbn = {978-3-031-14835-4}, pages = {144--157}, publisher = {Springer International Publishing}, title = {Comprehensive Analysis of Software-Based Fault Tolerance with Arithmetic Coding for Performant Encoding of Integer Calculations}, url = {https://link.springer.com/chapter/10.1007/978-3-031-14835-4_10}, year = 2022 }

For this purpose, a linear parameter-varying (LPV) model is derived as well as a system identification method is presented. Based on this, a gain-scheduled drive-based LPV damping control design is proposed, which guarantees stability and performance under variation of the manipulator configuration.

  @article{Brenner2021, abstract = {Rack-and-pinion drives are mainly used for large machine tools and are often operated with indirect position control. Due to the lack of state information on the output side, this results in reduced accuracy regarding the table position. In addition, the system can only react inadequately to disturbances outside the control loop, meaning that often insufficient results can be achieved in typical application scenarios such as milling. To meet the increasing dynamic and accuracy requirements of the modern manufacturing industry, this paper presents a highly dynamic acceleration-based disturbance compensation method. For this purpose, the table acceleration is estimated using a dynamical model of the drive train and compared to the signal from an additional acceleration sensor attached to the machine table. Based on the resulting difference, an additional compensation torque is provided, which suppresses the disturbance in counterphase. The approach is tested experimentally on an open control platform with industrial drive components and the behavior is investigated based on compliance frequency responses and externally applied milling forces. At the same time, a standardized parametrization methodology is developed and the robustness is evaluated by varying table masses. In summary, a considerable improvement of the dynamic disturbance behavior can be achieved compared to the conventional system without compensator.}, author = {Brenner, Felix and Lechler, Armin and Verl, Alexander}, day = 19, doi = {10.1007/s11740-021-01068-w}, issn = {1863-7353}, journal = {Production Engineering - Research and Development}, month = {07}, title = {Acceleration-based disturbance compensation for elastic rack-and-pinion drives}, url = {https://doi.org/10.1007/s11740-021-01068-w}, year = 2021 }

However, this freedom needs to be utilized by appropriate CAx tools. In this paper, we present a novel slicing method, enabling the automatic generation of topology-optimized Laminated Layer Manufacturing (LLM) parts. With this method a part of arbitrary shape can be automatically sliced and equipped with a uniform virtual grid that is suitable for manufacturing. The optimal density distribution is then mapped onto the individual slices and locally approximated through the introduction of variably shaped cavities. By using 3D modeling techniques all LLM sheets are modeled parametrically and assembled automatically. To verify the functionality of the presented method, it is applied to two practical parts and compared with a conventional topology optimization method.}, author = {Helfesrieder, Nico and Lechler, Armin and Verl, Alexander}, doi = {10.1016/j.procir.2020.04.048}, issn = {22128271}, journal = {Procedia CIRP}, pages = {38--43}, title = {Method for generating manufacturable, topology-optimized parts for Laminated Layer Manufacturing}, url = {http://www.sciencedirect.com/science/article/pii/S2212827120306144}, volume = 93, year = 2020 }

At the moment, this mostly vertical lift movement is executed separately from the position changing in the operating plane. This sequential processing of motions increases the non-productive time in processes with frequent changes of operating height, such as laser cutting. The reduction is realized by superimposing the planar path movements with lift motion. An asynchronous axis interpolation is applied to make use of the maximum machine dynamics. In addition, known obstacles can be taken into account by further parameters in the planning.}, author = {König, Timo and Verl, Alexander and Lechler, Armin}, booktitle = {13th IFAC Workshop on Intelligent Manufacturing Systems IMS 2019}, doi = {https://doi.org/10.1016/j.ifacol.2019.10.046}, eventdate = {12.

Dabei wird die rotatorische Bewegung des elektrischen Antriebsmotors über ein Getriebe und eine Ritzel-Zahnstange-Kombination in eine lineare Vorschubbewegung umgesetzt. Dieser Mechanismus weist, vor allem wenn es sich um Werkzeugmaschinen mit großen Abmessungen handelt, grundlegende Vorteile auf. Im Gegensatz zu KGTs, bei denen die resultierende Steifigkeit von dem der aktuellen Position des Tischs sowie vom Verhältnis der Verfahrlänge zum Spindeldurchmesser bestimmt wird, ist die Vorschubsteifigkeit des ZRA weitgehend konstant. Ein weiterer Vorteil liegt in der möglichen Kosteneinsparung bei langen Verfahrwegen hinsichtlich der notwendigen Sensorik zur Bestimmung der Tischposition. Diese wird indirekt über den Drehwinkel des Antriebsmotors bestimmt, was teure und lange Messsysteme zur direkten Bestimmung der Tischposition überflüssig machen. Aber gerade der mechanische Aufbau von Ritzel und Zahnstange im Verbund mit einer indirekten Positionsermittlung führen zu Umkehrspiel und somit zu einer geringeren Positioniergenauigkeit sowie geringer Systemstabilität.}, author = {Karim, Ali and Lechler, Armin and Verl, Alexander}, editor = {GmbH, Vereinigte Fachverlage}, journal = {Antriebstechnik}, language = {deutsch}, month = {04}, number = 4, pages = {116 - 117}, title = {Kompensation des Umkehrspiels bei Zahnstange-Ritzel-Antrieben}, url = {http://digital.antriebstechnik.de/antriebstechnik-4-2017/58127174/116}, year = 2017 }

The employed teach-in method for programming the process is time-consuming and, therefore, only suited for large lot sizes. Thus, manufacturing of small lot sizes or single parts still necessitates the handwork and expertise of workers pouring the molten metal into the mould. This creates a dangerous environment for the worker. In recent years researchers have developed a model-based process control, which allows precise casting control without having to previously teach the process. Usage of these process models has been limited to special process control systems, specifically designed for a certain machine. In this paper, a novel approach is presented, in which a \{NC\} (Numerical Control) system is enhanced by process models. Instead of programming the \{NC\} in kinematic coordinates, it will be shown that programming in process coordinates allows robust and flexible casting, even for small lot sizes. The paper will prove the feasibility of the approach by evaluation of the processing time of the model. }, author = {Birkhold, Markus and Friedrich, Christian and Lechler, Armin}, doi = {http://dx.doi.org/10.1016/j.ifacol.2015.10.102}, issn = {2405-8963}, journal = {IFAC-PapersOnLine }, note = {4th \{IFAC\} Workshop on Mining, Mineral and Metal Processing \{MMM\} 2015Oulu, Finland, 25–27 August 2015 }, number = 17, pages = {195 - 200}, title = {Automation of the Casting Process using a model-based NC Architecture }, url = {http://www.sciencedirect.com/science/article/pii/S2405896315019783}, volume = 48, year = 2015 }

The most common approach is to measure the billet temperature, which suffers from various drawbacks leading to difficulties in process stability. The main disadvantages are the small temperature range of the process window and the alloy composition dependency of the correlation between temperature and liquid fraction. An alternative is to determine the liquid fraction of the billet by measuring the time constant of the load. Although time constant measurement is not affected by the mentioned problems, it is difficult to use it as a controlled variable. This paper shows that disturbances affecting time constant measurement are mainly caused by semiconductor losses inside the inverter. A method is introduced to compensate these losses. This method was implemented and tested in the embedded system of an induction heating unit, thereby showing that it is possible to use time constant measurement to determine the liquid fraction of a billet during induction heating.}, author = {Gerlach, Oliver and Lechler, Armin and Verl, Alexander}, journal = {MEASUREMENT SCIENCE & TECHNOLOGY}, number = 2, pages = 025001, title = {Time constant measurement for control of induction heating processes for thixoforming}, volume = 26, year = 2015 }

To cope with the trend and the need for customized products and shorter product lifecycles, production systems need to be flexible and reconfigurable. Therefore, modular system-based engineering is the key to a quick, customized machine and plant (re-)configuration. This approach also enables the implementation of different functional requirements with a minimum amount of resources. By adding or removing modules to or from specific production steps, the overall operational capacity and efficiency of the system is optimized.The mentioned modules of a modular production system and the modularization of the modules hardware components itself are so far developed that a reconfiguration is possible within a few hours. However, modern control systems are not yet able to self-configure according to the present modules and sub-modules of the system. At present, a time- and manpower-consuming offline configuration is still needed. Nor is a validation of the generated control system configuration out of the box possible.This paper will present an overview concerning a new technology, enabling the control system to self-configure based on the information every hardware module is providing. Benefiting from the approach of Industry 4.0, within which every control system, defined as cyber-physical-system, connects to the internet, a time-efficient and completely automated reconfiguration of the control system is technically possible. Additionally, the automated validation of this configuration is enabled by the use of simulation software. Each module provides a self-description that is not only used for the automated configuration of the control, but supports higher-level systems as well.

Experimental results have shown that the application of the proposed strategies yield a significant improvement in the production rate of conforming parts of the system.

This uses energy prediction through a consumption graph and calculates operating state trajectories using a graph-based optimisation theory. These trajectories allow an energy-minimal spending of unproductive times. To ensure a widespread application, an automated parameter optimisation is proposed to adapt the consumption graph to the machine tool it is optimising automatically.

Chatter can leads to damage of the tool, the part or the machine tool. Therefore, the estimation and prediction of the process stability is very important. The process stability depends on the spindle speed, the depth of cut and the width of cut. In milling, the process conditions are defined in the NC-program. While the spindle speed is directly coded in the NC-program, the depth and width of cut are unknown. This paper presents a new simulation based approach for the prediction of the depth and width of cut of a milling process. The prediction is based on a material removal simulation with an analytically represented tool shape and a multi-dexel approach for the work piece. The new calculation method allows the direct estimation of the depth and width of cut, which are the influencing parameters of the process stability, instead of the removed volume as existing approaches do. The knowledge can be used to predict the stability of new, unknown parts. Moreover with an additional vibration sensor, the stability lobe diagram of a milling process can be estimated and improved based on the estimated depth and width of cut.}, author = {Friedrich, Jens and Gebele, Matthias and Lechler, Armin and Verl, Alexander}, journal = {International Journal of Mechanical, Aerospace, Induastrial, Mechatronic and Manufacturing Engineering}, number = 10, pages = {1981-1986}, title = {Determining the width and depths of cut in milling on the basis of a multi-dexel model}, url = {http://waset.org/publications/10002539/determining-the-width-and-depths-of-cut-in-milling-on-the-basis-of-a-multi-dexel-model}, volume = 9, year = 2015 }

Im Rahmen dieses Beitrags wird ein Konzept aufgezeigt, wie vornehmlich asynchrone CNC-Funktionen partitioniert werden können, indem die zu verarbeitenden Daten auf mehrere Instanzen einer Funktion aufgeteilt werden.

  @misc{LechlerEberspaecherBirkhold2014a, __markedentry = {[xtl:6]}, abstract = {Classic mechanical presses limit the flexibility of metal forming systems due to their fixed sinusoidal motion. Servo presses are no longer limited to a fixed sinusoidal motion, combining the free motion capability of hydraulic presses with the speed of classic mechanical presses. This new freedom of the press motion allows the integration of peripheral processes into the forming tool, thus reducing the necessity of follow-up processes. However, this new capability comes at the cost of increased complexity of the tool, which needs its own control system. Current techniques for the integration of peripheral systems lack granularity and need tedious hand tweaking. Therefore, many tool manufacturers have yet to embrace the new capabilities of servo presses. In this paper we introduce a novel approach, in which a press tool uses a middleware to automatically set-up the fieldbus configuration, during reconfiguration of the press. The considered peripheral system consists of three transfer modules which combine two forming parts in the tool for welding. The access to additional system data is necessary for the sophisticated transfer motions in this tool. Additionally, the necessity of manually tweaking the synchronization of the transfer is eliminated by this new approach. The capabilities of the new approach are demonstrated and validated against a state of the art controller. In addition, the possibility for raising the energy efficiency by purely control-related measures is shown by the example of the cutting production. Afterwards a method for modelling and simulating the energy consumption of manufacturing units is presented. In order to ensure a broad applicability, the modelling approach is a modular one and the application of the models is supported by an energy description language. This approach can also be used for modelling the energy input of presses.}, address = {Frankfurt}, author = {Lechler, Armin and Eberspächer, Philipp and Birkhold, Markus}, pages = {73-87--}, publisher = {Werkstoff-Informationsgesellschaft mbH}, title = {Control based methods for an efficient production: Control based methods for an efficient production}, year = 2014 }

Servopressen hingegen sind nicht mehr auf solch eine Bewegung beschränkt, da sie die Bewegungsfreiheit der hydraulischen Pressen mit der Geschwindigkeit der klassischen mechanischen Pressen vereinen. Die neue Bewegungsfreiheit der Pressen erlaubt die Integration peripherer Prozesse in das Umformwerkzeug und verringert die Notwendigkeit nachfolgender Prozessschritte. Dennoch geht diese neue Fähigkeit auf Kosten einer erhöhten Komplexität des Werkzeugs, das ein eigenes Steuerungssystem benötigt. Heutigen Techniken für die Integration peripherer Systeme fehlt es an Granularität und sie erfodern langwierige manuelle Optimierung. Daher müssen viele Werkzeughersteller sich erst noch mit den neuen Möglichkeiten der Servopressen vertraut machen. In dieser Veröffentlichung wird ein neuartiger Ansatz vorgestelt, bei dem ein Pressenwerkzeug eine Middleware benutzt, um automatisch die Feldbuskonfiguration während der Rekonfiguration der Presse zu starten. Das betrachtete periphere System besteht aus drei Transfermodulen, die zwei Umformteile im Schweißwerkzeug kombinieren. Der Zugang zu zusätzlichen Systemdaten ist für die differenzierten Transferbewegungen in diesem Werkzeug notwendig. Außerdem fällt bei diesem Ansatz die Notwendigkeit des manuellen Optimierens der Transfersynchronisation weg. Die Möglichkeiten des neuen Ansatzes werden aufgezeigt und gegen eine Steuerung aus dem Stand der technik validiert. Darüber hinaus wird die Möglichkeit zur Steigerung der Energieeffizienz durch rein steuerungstechnische Maßnahmen am Beispiel der spanenden Produktion aufgezeigt. Im Anschluss daran wird eine Methode zur Modellierung und Simulation des Energieverbrauchs von Fertigungseinrichtungen vorgestellt. Um die breite Einsetzbarkeit sicherzustellen, ist der Modellierungsansatz modular ausgeführt und die Anwendung der Modelle selbst wird durch eine Energiebeschreibungssprache unterstützt.
