Milling Surface Roughness Acoustic Sensor Dataset

This dataset comprises 7444 audio files containing acoustic signal samples recorded using a 44.1KHz microphone (in .au format) during the milling of mild steel with a tungsten carbide tool on a BFW YF1 vertical milling machine. Various combinations of feed (5mm and 10 mm), speed (250 rpm and 500 rpm), and depth of cut (0.25mm, 0.50mm, 0.75mm,1.0mm) were used, and surface roughness values measured using a Carl Zeiss E-35B profile-meter are provided for each combination as a .xlsx file.

本数据集包含7444条音频文件，其中存储了采用44.1kHz麦克风录制的声学信号样本，录制场景为在BFW YF1立式铣床上使用硬质合金刀具铣削低碳钢（mild steel）的加工过程，音频格式为.au。本次实验采用了进给量（5mm与10mm）、主轴转速（250转/分钟与500转/分钟）以及背吃刀量（0.25mm、0.50mm、0.75mm、1.0mm）的多种参数组合；针对每一组参数组合，均提供了使用卡尔蔡司E-35B轮廓仪（profile-meter）测得的表面粗糙度值，相关数据以.xlsx格式文件形式提供。
