A new open dataset from a milling process – data for classification and estimation of tool life

The data set contains raw data (Pxxx_Fyy_Czz.csv files) and processed data (a file with designated features - FeatureAndMetadata_Milling.csv) from the full life cycle of 14 cutting tools used in the milling process. The tools performed 968 milling cycles. The data contain vibration signals (8 measuring channels from the spindle and work table) and current signals (12 measuring channels from the spindle and work table). A metadata file is also available, in which each cycle is assigned process data (e.g. tool number, sample number, sample hardness) The data set is useful for work on the classification of tool condition or estimation of their service life. It is possible to use only FeatureAndMetadata_Milling.csv and work with calculated features or download all files and work with raw data.

本数据集涵盖铣削加工场景下14把切削刀具全生命周期的原始数据（文件格式为Pxxx_Fyy_Czz.csv）与处理后数据（包含指定特征的文件FeatureAndMetadata_Milling.csv）。上述刀具共计完成968次铣削循环。采集的数据包含两类信号：来自主轴与工作台的8路测量通道的振动信号，以及来自主轴与工作台的12路测量通道的电流信号。另有元数据文件可供使用，其中为每个铣削循环分配了加工相关参数，例如刀具编号、样本编号、样本硬度等。本数据集可应用于刀具状态分类或刀具寿命评估相关研究工作。使用者既可以仅调用FeatureAndMetadata_Milling.csv文件，基于已计算得到的特征开展研究，也可下载全部文件，使用原始数据进行相关工作。
