In highly dynamic materials processing, especially in cutting and welding of thin metal sheets, the application of laser techniques was restricted in the past, although lasers delivering the laser power and quality required for high speed processes were available. Besides limited acceleration of driving systems, the weight and stability of the components in motion were the reason for these restrictions. New concepts are necessary to create both a light-weight laser head with its components and new machine components on the basis of closed cinematic chains with fast drive devices. The know-how for the development of such systems in a modular and configurable set-up was elaborated in the collaborative research centre 349 at the University of Stuttgart.On this basis, light-weight components for beam forming and diagnostics, for process control, and for the delivering of process gases have to be designed and integrated into the light-weight structure of the new laser head. The high requirements concerning the drive devices such as a travel speed of 300 m/min and an acceleration in the path of 4 g are only met by a consequent application of the results of the SFB 349 by a) machine kinematics in a hybrid manner (parallel, serial), b) drive modules with a light-weight structure and c) linear direct drives as a stiff module.After finishing the theoretical and experimental investigations in the first year of research-work a demonstrator will be built and tested in industry.

在高动态材料加工中，特别是在薄金属板的切割和焊接中，激光技术的应用在过去受到限制，尽管激光器可以提供高速加工所需的激光功率和质量。除了驱动系统的加速度有限外，运动部件的重量和稳定性也是这些限制的原因。新的概念是必要的，以创建一个重量轻的激光头及其组件和新的机器组件的基础上封闭的电影链与快速驱动装置。斯图加特大学的349合作研究中心详细阐述了以模块化和可配置设置开发此类系统的专有技术。在此基础上，必须设计用于光束形成和诊断、过程控制以及工艺气体输送的轻质组件，并将其集成到新激光头的轻质结构中。对于驱动装置的高要求，例如300 m/min的行驶速度和4 g的行程加速度，只能通过以下方式来满足：a）混合方式的机器运动学（并行，串行），B）具有轻质结构的驱动模块，以及c）线性直接驱动器作为一个刚性模块。在完成第一年的研究工作的理论和实验研究后，将建立一个演示器，并在工业上进行测试。
