Numerous efforts have been made to assess and model the power consumption of machining process, which has led to many standards for energy labeling of machine tools. However, more investigation is required to improve the applicability of these standards because the energy patterns of machines vary widely with respect to the machine type, size, and configuration. Hence, it is aimed to develop a methodology to determine the power consumption characteristics of a wide variety of machine tools. This research focuses on the power consumption of feed drive units, which are largely varying components with respect to machine tool configurations. Two notable phenomena were observed during our experiments. First, the power consumption of an axis in the gravitational direction exhibited a different pattern from that along those of the other axes. Movement in the gravitational direction was investigated in more detail from the perspective of the machine tool configuration. Second, during multi-axis movement, no power correlation between different axes was confirmed. Regardless of the axis composition, no correlation was detected between the individual power consumption profiles of each axis. Elucidating the power consumption characteristics of feed drive units would contribute toward standardization and simplification of power measurement procedures.

机床进给驱动单元的功耗评估

为了评估和建模加工过程的功耗已经做出了许多努力，这导致了机床能量标签的许多标准。但是，需要进行更多的研究来提高这些标准的适用性，因为机器的能量模式在机器类型，尺寸和配置方面存在很大差异。因此，目的在于开发一种确定各种机床的功耗特性的方法。这项研究的重点是进给驱动单元的功耗，进给驱动单元是相对于机床配置而言变化很大的组件。在我们的实验中观察到两个值得注意的现象。首先，一个轴在重力方向上的功耗显示出与其他轴上的功耗不同的模式。从机床配置的角度更详细地研究了重力方向上的运动。其次，在多轴运动期间，未确认不同轴之间的功率相关性。无论轴的组成如何，在每个轴的各个功耗曲线之间均未检测到相关性。阐明进给驱动单元的功耗特性将有助于功率测量程序的标准化和简化。
