本文提出了一种新颖、简便的刀具故障检测方法。基于切削力信号的熵值和相关性，提出了一种利用硬质合金刀具车削高强度、高硬度材料的EEMD滤波重构方法。然后，利用重构后的切削力信号，采用摩擦系数和平均功率理论表征刀具失效状态；最后，在前面分析的基础上，提出了一种利用CUSUM控制图实时监测刀具切屑和刀具磨损失效的自动检测仪，并通过半精加工实验进行了验证。该方法不需要其他传感器设备，计算时间长，在工具故障实时检测中操作简单可靠。
This paper developed a novel, simple-to-use method for detecting tool failure in cutting. An EEMD filtering and restructuring method is launched according to entropy and correlation of cutting force signal in turning high-strength and high-hardness materials using carbide cutting tools. Then, friction coefficient and mean power theories are adopted to characterize tool failure status using restructured cutting force signal. Finally, an automatic detector is proposed using CUSUM control chart to monitor tool chipping and tool wear failure in real time based on previous analysis and can be verified by semi-finishing experiment. Without any need of other sensor equipment and long computing time, the method can be reliable and simple to operate in detecting tool failure in real time.
