Basic investigations on the application of the pulse compensation for linear direct drives in a cross-slide

本计画的研究目的是验证耦合轴结构脉冲补偿的有效性。该研究将基于基础工作，如十字滑块的设计和装配以及在第一个项目期间进行的Matlab / Simulink模型。在此基础上，对脉冲补偿方法进行了改进、实现和实验研究。在第一个项目期间开发和优化的十字滑块将通过实验对其静态和动态特性进行初步研究。在第一个项目期间开发的横向滑道的全面DBS模型必须扩展机器的弹性特性，然后与上述实验中确定的特性进行比较。通过该模型，将进行具有预测目标路径的脉冲补偿方法的进步的模拟研究。随后，模拟结果将通过实施这些方法到控制的横向滑动，因此，可压缩的结构激励的减少将实验证明。最后，十字滑块将安装在一个现有的框架与HSC铣削主轴和第三个运动轴，这将使它成为一个3轴铣床。在确定其精度后，机床将被用来证明上述脉冲补偿方法对定义的加工过程的实用性。

The research objective of this project is to proof the efficiency of pulse compensation for coupled axes structures. The research will be based on the fundamental work, such as the design and assembly of the cross slide and on the Matlab / Simulink models, performed in the first project period. On this basis, the method of pulse compensation has to be improved, implemented and investigated by means of experiments and simulations. The cross slide which was developed and optimized in the first project period will initially be studied regarding its static and dynamic properties by means of experiments. A comprehensive DBS model of the cross slide, developed in the first project period, has to be extended with the machines elastic properties and then compared with the properties determined in the experiments mentioned above. By means of this model, simulation studies of the advancements in the pulse compensation method with predicted target pathways will be performed. Subsequently, the simulation results will be verified by implementing these approaches into the control of the cross slide and, hence, the accomplishable reductions of structural excitations will experimentally be demonstrated. Finally, the cross slide will be installed on an existing frame with a HSC milling spindle and a third axis of motion, which will make it a 3-axis milling machine. After determining its precision, the machine will be used to demonstrate the practicability of above mentioned pulse compensation methods for defined machining processes.
