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

金属切割带锯是一种快速高效的加工方法，用于多种任务的预加工。然而，由于切割损失大、切割质量差和刀具寿命短，带锯的成本很高，这一点变得很明显。在本项目的框架内，将研究影响带锯过程的带锯片张力，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。因此，将创建带锯的虚拟过程模型，该模型允许模拟切割参数和机器特定边界条件的影响，以加速开发新的自适应控制概念，用于带锯中的带锯片张力。在本项目开始时，将通过实验调查来分析带锯过程，以确定作用在带锯片和整个机器上的力。这些检验将通过ANSYS Workbench进行广泛的计算机辅助有限元模拟来支持。本文的研究成果将用于利用MATLAB/Simulink建立虚拟过程模型。在这个项目的第二部分，不同的概念，自适应控制的带锯片张力在带锯机将被开发。这些概念将在虚拟流程模型中实现，并对其控制行为进行分析。最后，通过实验对自适应控制的带锯片张力进行了验证。

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.
