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.

带锯金属切割作为一种快速高效的工艺，用于多种任务的预加工。然而，显而易见的是，带锯由于大的切割损失、差的切割质量和短的工具寿命而导致高成本。在本项目的框架内，影响带锯过程的带锯刀片张力将被检查，以开发自适应控制概念，以提高切割质量和刀具寿命，这将提高整个过程的生产率。因此，将创建一个虚拟的带锯过程模型，它允许模拟切割参数和机器特定的边界条件的影响，以加速开发新的自适应控制概念的带锯中的带锯刀片张力。在本项目开始时，将通过实验研究分析带锯过程，以确定作用在带锯刀片和机器整体上的力。这些检查将得到大量的计算机辅助有限元模拟与ANSYS的支持。研究结果将用于MATLAB/Simulink中建立虚拟过程模型。在本项目的第二部分，将开发用于带锯机中的带锯条张力的自适应控制的不同概念。这些概念将在虚拟过程模型中实现，并分析它们的控制行为。最后，对带锯机锯条张力的自适应控制进行了实验研究。
