Development of a process model for the simulation of adaptive control concepts for metal-cutting bandsawing

带锯金属切割是一种快速、高效的加工方法，可用于多种任务的前加工。然而，很明显，由于切割损失大、切割质量差和刀具寿命短，带锯造成了高成本。在该项目的框架内，将研究影响带锯加工过程的带锯片张力，以开发自适应控制概念，以提高切割质量和刀具寿命，从而提高整个过程的生产率。为此，将建立一个虚拟的带锯锯切过程模型，该模型可以模拟锯切参数和特定于机器的边界条件的影响，以加速开发新的带锯片张力自适应控制概念。在本项目开始时，将通过实验研究对带锯过程进行分析，以确定作用在带锯叶片和整个机器上的力。这些检查将得到广泛的计算机辅助有限元模拟的支持，使用的是ansys工作台。本文的研究成果将被用来利用MATLAB/SIMULINK建立虚拟过程模型。在本项目的第二部分中，将提出不同的概念来实现带锯片张力的自适应控制。这些概念将在虚拟流程模型中实现，并针对它们的控制行为进行分析。最后，对自适应控制的带锯片张力进行了实验验证。

Metal cutting with bandsaws is used in pre-machining for manifold tasks as a fast and efficient process. Nevertheless it becomes apparent that bandsawing causes high costs due to large cutting losses, a poor cutting quality and a short tool life. Within the framework of this project, the bandsaw blade tension influencing the bandsawing process will be examined to develop adaptive control concepts for improving cutting quality and tool life, which will increase the productivity of the overall process. For this reason, a virtual process model for bandsawing will be created, which allows simulating the influence of cutting parameters and machine-specific boundary conditions to accelerate the development of new adaptive control concepts for the bandsaw blade tension in bandsaws. At the beginning of this project, the bandsawing process will be analyzed by experimental investigations to determine the forces acting on the bandsaw blade and the machine as a whole. These examinations will be supported by extensive computer-aided FE simulations with ANSYS Workbench. The results of this research will be used to create the virtual process model with MATLAB/Simulink. In the second part of this project, different concepts for the adaptive control of the bandsaw blade tension in bandsaws will be developed. These concepts will be implemented in the virtual process model and analyzed regarding their control behavior. Finally, the adaptively controlled bandsaw blade tension in the bandsaw will be examined by experiment.
