    Tool monitoring with the Neuro Fuzzy method. Intelligent systems are conquering wide areas of automation engineering. With their help, a number of partly complex tasks can be better solved than before. Today, Neuro Fuzzy techniques are among the currently discussed approaches in this area but they are not yet well established. The article describes the working procedure and application of a Neuro Fuzzy algorithm by taking an example from the tool monitoring sector.

    Modern computerised numerical control systems provide a lot of functions to the user. During configuration and operation of the CNC a couple of difficulties have to be solved. The user expects to be supported efficiently by the machine producer. A fast and simple contact between user and producer has to be installed in the kind of a CNC integrated remote service system. As the operator has an increasing responsibility for the machine, there is a further need for process supervision and diagnosis of the electromechanical components. The overall target is to achieve a high degree of availability of the machine. The paper describes a unique system for an CNC integrated remote diagnosis and supervision, process supervision for milling and model based diagnosis for feed drives, which was implemented into a new open CNC generation.

    Neuro-fuzzy technologies for process assurance. In the past, approaches for a solution of artificial intelligence have been applied to numerous problems occuring on the sector of automation engineering. After a phase of euphoria, the results obrained were frequently unsatisfactory. In the beginning of the nineties, the new concept "Neuro Fuzzy" emerged. The present article discusses principles and major methods at an example from the sector of tool monitoring.

    Integration of monitoring procedures into the CNC. The mounting demands made on the performance of modern machine tools require an ever growing amount of functionality to be included into the machine's environment. Here, monitoring of the machining process plays a vital part. This article discusses the criteria for integrating machine monitoring systems into the CNC and describes the resulting demands on the monitoring system and on open controls.

    Die im Beitrag vorgestellte Verwendung der Achsantriebsströme zur automatischen Werkzeugüberwachung stellt eine besonders kostengünstige Lösung dar. Dies liegt zum einen am Wegfall jeglicher Sonsorik, zum anderen an der ausschließlichen Nutzung der steuerungsinternen Prozessorkapazität. Bei der Drehbearbeitung ist mit den vorhandenen Softwaremodulen eine sichere Überwachung von Schrupp-, Plan- und Abstechvorgängen durch ein CNC-internes Softwarepaket möglich. Durch die Integration in die Steuerung ist die Kommunikation zwischen NC-Programm und Überwachungsroutine vereinfacht, wodurch bei Werkzeugbruch kürzeste Reaktionszeiten möglich sind. Minimierte Anforderungen an Speicher- und Prozessorkapazität schaffen die Voraussetzung für eine Implementierung in offene Steuerungssysteme.

    The article introduces a procedure for the automatic recognition of tool wear and breakage which was developed in close cooperation between a lathe manufacturer and a research institute and was fully integrated into the control of different versions of automatic lathes. The procedure is beeing applied industrially since May of this year.

    At the IPK-Berlin a proceed for the diagnosis of machine axes was developed, which can detect and monitor the state of an axis without the use of sensors. A minimal expense of hardware guarantees particular efficiancy for operator support during setting up the machine and service. This subscription will monitor the potentials of a sensorless state supervision for machines by application of "intelligent" identification and classification methods. As these methods can easily be adapted to different electromechanical components, the system could attract a wide circle of industrial users.
