“If the machine stops, it can be manually disengaged. However, if it restarts in the wrong position without the affected part being immediately ejected, it will result in a double processing. For threads, this means rejection.„ Therefore, a solution was sought for premature and preventive detection. A solution that should also be supplemented with tool life monitoring, because although Eisenmann only processes problem-free aluminum alloys, casting, e.g., due to blowholes, can lead to higher tool wear. As a result of these requirements, it quickly became clear to those responsible that they wanted to invest in professional process monitoring. At the same time, they received a recommendation for UTTec's monitoring systems. From today's perspective, this recommendation was absolutely effective for Lars-Jan Szymanski, CEO at Eisenmann Druckguss: “We had clearly defined the requirements, but the problem was that we have older and newer machining centers in use, and therefore the controls are also different. This ranges from Siemens 840d Powerline to 840dsl Solution Line, including different generations of software." Despite these conditions, UTTec was able to offer and install secure monitoring.

通过尽早透明化问题 识别

目前，五轴多主轴加工中心正在使用UTTec的UT-Tm®-Basic监控系统进行操作。在菲林根-施文宁根，现在可以非常有信心地说：流程中的不确定性已经得到解决，并已成为过去，合格产品的数量也得到了可衡量的提高。然而，为了优化节拍时间，系统尚未在所有机器上得到充分利用。UTTec总经理Uwe Schröter并未将此视为问题：„系统是最近才安装的，目前Eisenmann还没有足够的人力。但我们已经解决了双面加工问题，并在两台机器上优化了节拍时间。每台机器都在加工不同的产品，因此我们需要逐步调整每台机器。尽管如此，我们仍然通过互联网与Eisenmann Druckguss保持联系。“具体来说，UT-Tm®-Basic系统配备了VNC服务器。UTTec通过互联网连接到Web软件和数据分析UT-Da®。数据将在Winnenden进行分析，并通过远程维护进行调整。其优点是可以做出判断并提供支持，而无需耗时且成本高昂的差旅。UT-Da®可以详细记录机器运行时间、停机原因、辅助时间等。因此，在上述两台加工中心上，节拍时间得到了可衡量的优化。而且，不久之后将着手记录刀具寿命。.

最后，问题来了，如此专业的流程监控在如此不同代际的机器和控制系统上是否划算。Lars-Jan Szymanski 给出了一个明确的„是“：“当然，这样的投资是有意义的。根据产地不同，机器的运行时间也会因维护、保养和护理情况的不同而异。但有了监控系统，它们的运行时间更长，因为避免损坏就意味着延长使用寿命。此外，还能降低停产的风险。” 在这方面，有趣的一点是，由于系统的透明性，问题甚至能在早期就被发现。例如，UTTec 在 Eisenman Druckguss 发现一台机器的电流值过高。随后，通过优化转速和进给值，主轴的振动得到了极大降低。.
