  @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 }

In order to fulfill the accuracy requirements of electric drives for production equipment, a high switching frequency is typically used. This results in high switching losses which are proportional to the switching frequency. However, a high accuracy is not always required. Therefore, a method for adapting the switching frequency of the drive inverter during runtime when high accuracy is not required is presented in this paper. The method includes the identification of operating states of the machine tool, automatic calculation of the controller parameters and strategies for changing the PWM frequency during runtime.

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.

A required key feature for the application of control applications is deterministic real-time behavior of such networks. With the presence of IEEE 802.1 TSN, there is a promising vendor and application independent networking technology available. This paper analyzes typical parameters and requirements of fieldbus technology which is used today for real-time applications and their relation to TSN mechanisms within convergent networks. Also, the potential of future realizations using TSN in conjunction with OPC UA Pub/Sub is shown. Focus is laid on specific challenges which will require some further work to enable fieldbus-like performance over such infrastructures.}, address = {www.weka-fachmedien.de}, author = {Henke, Torben and Zahn, Peter and Frick, Florian and Lechler, Armin}, editor = {Sturm, Matthias}, eventdate = {27.02 - 01.03.2018}, eventtitle = {embedded world Conference}, isbn = {978-3-645-50173-6}, language = {eng}, publisher = {WEKA FACHMEDIEN GmbH}, title = {TSN and OPC UA for Industrial Automation}, year = 2018 }

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.

Regarding drive controls, reconfigurable hardware can be used to implement sophisticated control loops for which state of the art processor-based platforms are not performant enough. This capability was verified using FPGA-based prototyping systems, providing easy to use development processes.However, to date, no standard industrial drive control utilizes and benefits from this technology. A key factor for this is that besides the design of the control loop itself, its integration into a drive control system is crucial for industrial use, including functional, process, communication and safety aspects. While available tools are focused on the control loop implementation, the latter requirements are not currently fulfilled.In the context of the presented research, a new module-based approach was developed, providing a holistic solution for all the requirements. Thereby, the design of a control loop is based on basic blocks which not only provide the mathematical functionality, but also features to fit into a drive control system.

This uses energy prediction through a consumption graph and calculates operating state trajectories using a graph-based optimisation theory.

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.

In current production scenarios, End-Of-Line (EOL) inspection is applied to determine the quality of the assembled final product. The work presented in this paper is developed in the project MuProD, which aims at developing an innovative quality control system to change the current concept of \{EOL\} quality control. The case under investigation is the production of electric drives where the rotor is composed of several magnetized stacks. The magnetic properties of each stack differ due to variations of the single magnets and the magnetization process itself. In addition, handling of the magnets within the production line may cause cracks that decrease the strength of the magnetic field. This paper proposes a new solution for deviation compensation in the production of electric drives by selective assembly based on a crisp classification and a Mamdani style fuzzy inference system. The magnetic field of each stack is measured after the magnetization stage, yielding a discrete space-resolved magnetic profile. This magnetic profile is transformed into another feature space through a combination of feature selection and feature extraction to reduce the dimension. Based on these new features, the stacks can be classified into crisp sets. In the second part, an appropriate fuzzy rule base for the matching of the stacks is developed to obtain a uniform magnetic field of the rotor. By applying this assembly strategy, the rotor and consequently the final motor reaches desired quality targets although deviations in the single stacks are present. The benefits of the approach are validated within an industrial context. }, author = {Coupek, Daniel and Gülec, Aybike and Lechler, Armin and Verl, Alexander}, doi = {http://dx.doi.org/10.1016/j.procir.2015.06.074}, issn = {2212-8271}, journal = {Procedia \{CIRP\} }, note = {9th \{CIRP\} Conference on Intelligent Computation in Manufacturing Engineering - \{CIRP\} \{ICME\} '14 }, pages = {550 - 555}, title = {Selective rotor Assembly Using Fuzzy Logic in the Production of Electric Drives }, url = {http://www.sciencedirect.com/science/article/pii/S2212827115007179}, volume = 33, year = 2015 }

Durch den Einsatz von Threads können die Daten somit echt-parallel auf einem Multicore-System verarbeitet werden.}, address = {Düsseldorf}, author = {Keinert, Matthias and Lechler, Armin and Verl, Alexander}, booktitle = {VDI-Berichte 2231}, pages = {903-918}, publisher = {VDI Verlag}, title = {Multicore-CNC: Partitionierung numerischer Steuerungen zur Ausführung auf Multicore-Processoren}, volume = {Automation 2014}, year = 2014 }

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.
