    • A variable tuned holder for machine tools that attaches to a machine tool to act in a manner similar to a dynamic absorber while the machine tool is used during machining. The natural frequency of the holder may be matched to the natural frequency of the machine tool as the tool is in use to reduce the amplitude of vibration at the cutting end of tool with a workpiece. The present invention is designed to provide an impedance match between the machine tool and the holder such that the cutting energy may escape and/or be dissipated. The flexible holder may be used as one part of an overall system. The system may be designed to be used with tools of different shapes and/or lengths. As the shape and/or length of the machine tool changes, the system may be easily modified to change the natural frequency of the flexible holder to enable the dynamic absorber effect of the flexible holder to occur. The flexible holder may be included in a kit that may be used with a wide range of lengths and/or shapes of machine tools.
    • 用于机床的可变调节保持器,用于在加工过程中使用机床时,以机械工具的方式与动态吸收器类似。 保持器的固有频率可以与机床的固有频率相匹配,因为该工具正在使用中,以减少刀具在工件切割端处的振动幅度。 本发明被设计成提供机床和保持器之间的阻抗匹配,使得切割能量可以逸出和/或消散。 柔性保持器可以用作整个系统的一部分。 该系统可以被设计成与具有不同形状和/或长度的工具一起使用。 随着机床的形状和/或长度的变化,可以容易地修改系统以改变柔性保持器的固有频率,从而能够发生柔性保持器的动态吸收器效应。 柔性保持器可以包括在可以与各种各样的长度和/或形状的机床一起使用的套件中。

    • A method for predicting a tool point response of a spindle-holder-tool assembly to be used for high-speed machining applications is provided. The method includes determining direct and cross displacement-to-force receptances of a standard holder clamped in the spindle. The method also includes determining direct receptances at a free end of the standard holder based upon the determined direct and cross displacement-to-force receptances of the standard holder. Additionally, the method includes performing an inverse receptance coupling to simulate a decomposition of the standard holder into multiple subassemblies, the subassemblies including a spindle-holder base subassembly and an extended holder subassembly. The method further includes determining spindle-holder base subassembly receptances based upon the simulated decomposition of the standard holder.
    • 提供了一种用于预测用于高速加工应用的主轴保持器 - 工具组件的工具点响应的方法。 该方法包括确定夹在主轴中的标准夹具的直接和横向位移到力的接收。 该方法还包括基于确定的标准保持器的直接和交叉位移到力接收来确定标准保持器的自由端处的直接接收。 此外,该方法包括执行逆接收耦合以模拟标准支架分解成多个子组件,子组件包括主轴支架基座子组件和延伸的支架子组件。 该方法还包括基于标准支架的模拟分解来确定主轴支架基座子组件接收。
