This article discusses the problem of vibrations during machining. The manufacturing process of generator turbine blades is highly complex. Machining using Computerized Numerical Control (CNC) requires low cutting parameters in order to avoid vibration problems. However, even under these conditions, the surface quality and accuracy of the manufactured objects suffer from high levels of vibrations. Hence, the aim of this research is to counteract this phenomenon. Basic issues related to vibration problems will also be also discussed and a short review of currently available solutions for both active and passive vibration monitoring during machining will be presented. The authors developed a method which does not require any additional equipment other than modified CNC code. The proposed method can be applied to any CNC machine, and is especially suitable for lathes. The method seeks to eradicate the phenomenon of vibrations by providing enhanced control through Input Shaping Control (ISC). For this purpose, the authors present a method for modeling the machining process and design an ISC filter; the model is then implemented in the Matlab and Simulink environment. The last part of the article presents the results, together with a discussion, and includes a brief summary.
本文讨论了加工过程中的振动问题。发电机涡轮叶片的制造过程非常复杂。使用计算机数控（CNC）进行加工时需要低切削参数，以避免振动问题。然而，即使在这些条件下，所制造物体的表面质量和精度仍会受到高水平振动的影响。因此，本研究的目的是应对这一现象。还将讨论与振动问题相关的基本问题，并对加工过程中主动和被动振动监测的现有解决方案进行简要综述。作者开发了一种除了修改后的CNC代码外不需要任何额外设备的方法。所提出的方法可应用于任何CNC机床，尤其适用于车床。该方法旨在通过输入整形控制（ISC）提供增强控制来消除振动现象。为此，作者提出了一种加工过程建模方法并设计了一个ISC滤波器；然后在Matlab和Simulink环境中实现该模型。文章的最后一部分展示了结果并进行了讨论，还包括一个简要总结。
