Basics for the efficient use of multiaxial interpolating servo drives in processing machines

加工机器用于大规模需求商品的自动化生产。从经济的角度来看，需要不断增加个性化产品的产量。现代伺服驱动器通常用于实现个性化，即使在机器运行期间也可以灵活修改轨迹值（电子凸轮盘）。通过提高工序的工作率，可以提高产量。在实践中，如果在更高的工作速率下不再满足要求，则会出现问题，即过程不稳定、环境影响、能量消耗增加或产品质量下降。这限制了可达到的工作率。该项目的重点是通过改变工作率的限制来实现更高的工作率，从而提高产量。现代伺服驱动器通常未被使用的潜力被用于加工机械。在项目的第一年，基于三个关键问题开发了解决方案的基础。它包括（1）优化轨迹值的方法，其中可以模拟和考虑限制效应。对于选定的工作速率，轨迹值被优化。它们被放在一起成为（2）一组与工作速率相关的轨迹值。通过这种方式，可以修改所选择的工作速率相关特性。为了在真实的机床上使用该方法的潜力，开发了一个（3）控制系统，该系统能够以高精度执行与工作速率相关的轨迹值。与传统工艺相比，这为提高加工率提供了新的潜力。研究表明，采用与加工率相关的最佳轨迹值来提高加工率是可行的，具有较大的发展潜力。该解决方案的方法是在机器内运输的小尺寸货物（例如巧克力棒）的例子进行验证。在这里应用的项目的延续集中在解决方案的方法是如何适用于其他类型的生产过程。因此，第一个工作内容是模型库的增加，模型验证和必要的控制实施。第二个工作内容包括研究如何解决方案的方法是可用于其他类型的生产过程，通过改善，优化和控制框架。最后，将进行实验验证和演示。

Processing machines are used for automated production of commodities in mass demand. From economic point of view a constantly increasing production output of individualized products is required. Modern servo drives are often used to realize the individualization by enabling the flexible modification of trajectory values, even during operation of the machine (electronic cam disk). The production output can be increased by raising the working rate of the process. In practice, problems occur if at higher working rates requirements are no longer to be met, i.e. process instability, impact of surroundings, raising energy consumption or declining product quality. This limits the reachable working rate.The project focusses on the realization of higher working rates and thereby larger production output by shifting the limitation of the working rate. Commonly unused potentials of modern servo drives are utilized for the use in the context of processing machines.In the first years of the project, the basics of a solution approach based on three key issues were developed. It consists of (1) an approach to optimize trajectory values, wherein the limiting effects can be simulated and taken into account. For selected working rates trajectory values are optimized. They are put together to (2) a set of working rate-dependent trajectory values. On this way, selected working rate dependent characteristics can be modified. To use the potentials of the approach on the real machine, a (3) control system was developed, that enables the execution of the working rate-dependent trajectory values with high accuracy.With the new solution approach it is possible to realize alternative process solutions. This offers new potentials to increase the working rate compared with conventional processes. It has been demonstrated that it is possible to increase the working rate by using working-rate dependent optimized trajectory values, more potentials for development were shown. The solution approach was validated at the example of the intra-machine transportation of small-sized goods (e.g. chocolate bars).The continuation of the project applied here focusses on how the solution approach is usable for other types of production processes. Thereby, the first working content is the increase of the model base, the model validation and necessary control implementation. A second working content contains researches on how the solution approach is usable for other types of production processes by improving both, the optimization and the control framework. Finally, an experimental proof and demonstration will be performed.
