“…This new technology is mainly studied and applied to machining centers (MCs) for high speed milling (HSM), the manufacturing of complex dies, moulds and aerospace parts currently being a strategic sector of production engineering. Almost a hundred relevant papers [7,[22][23][24][25] have recently been published on these topics in leading engineering journals and presented at several technical conferences; this confirms the significant interest, both industrial and academic, in virtual design.…”

Increasing demands on the productivity of complex systems, such as manufacturing machines and their steadily growing technological importance will require the application of new methods in the product development process. A smart machine can make decisions about the process in real-time with plenty of adaptive controls. This paper shows the simulation based mechatronic model of a complex system with a better understanding of the dynamic behavior and interactions of the components. This offers improved possibilities of evaluating and optimizing the dynamic motion performance of the entire automated system in the early stages of the design process. Another effect is the growing influence of interactions between machine components on achievable machine dynamics and precision and quality of components. The examples cited in this paper, demonstrate the distinguishing feature of mechatronic systems through intensive integration. The case studies also show that it will no longer be sufficient to focus solely on the optimization of subsystems. Instead it will be necessary to strive for optimization of the complete system. The interactions between machine components, the influence of the control system and the machining process will have to be considered during the design process and the coordination of feed drives and frame structure components.

Friction stir welding (FSW) is a promising joining technology that is quickly becoming the preferred joining process for a wide range of applications. Because of their high static values, the process forces occurring during FSW still are a major factor concerning the development or the choice of friction stir welding machines. However, until now, the vast majority of research projects only consider the static force components or the maximum loads that occur during a given welding operation. But, like during turning or milling, the tool does generate oscillating process forces that induce vibrations into the machine structure and should not be neglected. Thus, the key aspect of this work is the comprehensive characterization of the dynamical nature of the process forces and their effect on the machine structure. These results are then used for the development of a process force model and the design of a machine model to simulate the response to these loads. These two models are combined in one simulation environment and interact with each other to predict the process stability for a certain combination of process parameters and machine.

“…Existing models thus can be further used for the simulation of process and structure interactions with a minimum additional modeling effort. The present contribution hence introduces a concept with a parameterized FEM model, which takes into account the position-dependent structural behavior and additionally integrates a detailed representation of the ball screw feed drive systems [18,19]. The latter permits the direct FEM modeling of the motor shaft and the ball screw, thus assuring a realistic force/torque straining in the mechanical transmission system.…”

The consideration of the dynamic interaction between the machine tool structure and the cutting process is a prerequisite for the simulative prediction and optimization of machining tasks. However, existing cutting force models are either dedicated to already examined manufacturing operations or require extensive measurements for the determination of cutting coefficients. In this context this paper outlines a modular, analytical cutting force model applicable to common turning processes. It takes into account the dynamic material behavior, nonlinear friction ratios on the rake face as well as heat transfer phenomena in the deformation zones. On the part of the machine tool structure a parametric model based on the Finite Element Method (FEM) is implemented. Both models are coupled for the simulation of process and structure interactions, whereas the influence of the control system is considered as well. The simulation results were verified experimentally on a turning center.
