DINOS (Diverse INdustrial Operation Sounds)

DINOS (Diverse INdustrial Operation Sounds) is a large-scale, open-access dataset consisting of over 74,000 audio samples totaling more than 1,093 hours, collected from a wide range of industrial acoustic scenarios. It covers diverse manufacturing processes, materials, and operating conditions to comprehensively represent industrial sound characteristics. The dataset includes recordings from CNC cutting operations, additive manufacturing (AM) processes, and designed anomaly scenarios. For cutting, data were collected from two CNC machines: Haas VF-2 and Yornew VMC-300. The VF-2 recordings capture inactive, machining, and warm-up states, while the VMC-300 machines aluminum (Al-6060) under varying spindle speeds and feed rates to induce chatter—a self-excited vibration that excites the system’s natural frequencies, degrading surface finish and tool life. Additional, unlabeled machining sounds were acquired from an APEC SK2540 CNC system. For AM processes, DINOS includes data from Renishaw’s LPBF and FormAlloy’s DED machines, capturing both idle and operational states, with events like fan activation, axis motion, and laser firing reflected in the acoustic signatures. Cold spray data were recorded using both a stethoscope sensor attached to the powder feeder and a microphone in an open area, enabling detection of faults such as gas flow interruptions, powder clogging, and feedstock depletion. Finally, a microphone installed on a shop floor with multiple machines captured ambient industrial sounds, including tool operations, fan noise, and high-pressure air discharge.多样化工业运行声响数据集（Diverse INdustrial Operation Sounds，简称DINOS）是一个大规模开放获取数据集，包含超过74000条音频样本，总时长超1093小时，采集自多种工业声学场景。该数据集涵盖多样化的制造工艺、物料与运行工况，可全面表征工业声响的特征属性。数据集包含数控切削（Computer Numerical Control，CNC）作业、增材制造（Additive Manufacturing，AM）工艺与设计性异常场景的录音。针对数控切削场景，数据采集自两台数控机床：Haas VF-2与Yornew VMC-300。VF-2的录音涵盖待机、切削加工与预热三种工况；而VMC-300则在不同主轴转速与进给速率下加工Al-6060铝合金工件，以诱发颤振——这是一种自激振动，会激发系统固有频率，进而降低工件表面质量与刀具使用寿命。此外，数据集还从APEC SK2540数控系统中采集了未标注的加工声响数据。针对增材制造工艺，DINOS包含雷尼绍（Renishaw）的激光粉末床熔融（Laser Powder Bed Fusion，LPBF）设备与FormAlloy的定向能量沉积（Directed Energy Deposition，DED）设备的数据，涵盖待机与运行两种工况，其声学特征可反映风机启动、轴运动与激光发射等事件。冷喷涂数据则通过两种方式采集：一是将听诊式传感器安装在送粉器上，二是在开阔区域布置麦克风，可实现气流中断、粉末堵塞与原料耗尽等故障的检测。最后，数据集在多设备运行的车间现场安装麦克风，采集环境工业声响，涵盖刀具作业、风机噪声与高压空气排放等场景。
