HF-dataset from Edge Device

The high-frequency (HF) data is retrieved from the Spinner U5-630 milling machine via an Edge Device. This data has a sampling rate of 2ms and hence, a frequency of 500Hz. The HF-data is from various experiments performed. There are 2 experiments performed (parts 1 and 2). The experimented part 1 has 12 .json data files and part 2 has 11 .json files. In total, there are 23 files of HF-data from 23 experiments. The HF-data has vast potential for analysis as it contains all the information from the machine during the machining process. One part of the information was used in our case to calculate the energy consumption of the machine. Similarly, the data can be used for retrieving information of torque, commanded and actual speed, NC code, current, etc. The spindle input power was varied for every experiment to analyze the effects on machining of both parts with varying geometry.

本数据集的高频（high-frequency, HF）数据通过边缘设备（Edge Device）从Spinner U5-630铣床采集获取。该数据的采样间隔为2毫秒，对应采样频率为500Hz。本数据集涵盖两类加工实验场景，分别对应工件1与工件2的加工实验；其中工件1相关实验包含12个.json格式数据文件，工件2相关实验包含11个.json格式数据文件，总计23个高频数据文件，对应23次独立实验。该高频数据涵盖了加工过程中机床的全部运行信息，具备极高的分析应用潜力。在本研究中，我们利用其中部分信息计算了机床的能耗。同理，该数据还可用于提取转矩、指令转速与实际转速、数控（Numerical Control, NC）代码、电流等各类机床运行参数信息。每组实验均设置了不同的主轴输入功率，以分析其对两种不同几何形状工件加工过程的影响。
