Machining of shafts characterized by a high compliance is difficult due to the occurrence of self-excited chatter vibrations. It is possible to limit their occurrence through the appropriate selection of technological parameters. For a proper selection of these parameters it is necessary to know the dynamic properties of the machine-tool-workpiece. This study proposes an approach through which these properties can be determined as a result of the synthesis of the dynamic properties of the system, using the receptance coupling method. Knowledge of these properties allows us to select the technological parameters of the lathe using the assistance system integrated into the CNC (Computerized Numerical Control). The final section of this work presents the experimental validation of the assistant and proposed procedures.
具有高柔度特性的轴类零件加工因自激颤振的出现而困难。通过适当选择工艺参数可以限制其发生。为了正确选择这些参数,有必要了解机床-工件的动态特性。本研究提出了一种方法,通过该方法可以利用传递导纳耦合方法,根据系统动态特性的综合结果来确定这些特性。了解这些特性使我们能够使用集成到计算机数控(CNC)中的辅助系统来选择车床的工艺参数。本文最后一部分介绍了该辅助系统及所提程序的实验验证。
