It is required for a cutting tool monitoring system to alarm rapidly because of the burst property and the harmfulness of the tool breakage. In this paper, the variation rule of the cutting vibration signals during tool fracture was experimentally investigated, and an approach to monitor tool breakage by the deviation of the average value component and the short duration disappearance of the high frequency component of the signal was proposed. By using microcomputer based monitoring system,...

It is required for a cutting tool monitoring system to alarm rapidly because of the burst property and the harmfulness of the tool breakage. In this paper, the variation rule of the cutting vibration signals during tool fracture was experimentally investigated, and an approach to monitor tool breakage by the deviation of the average value component and the short duration disappearance of the high frequency component of the signal was proposed. By using microcomputer based monitoring system, some satisfactory test results were obtained.

刀具破损的突发性和危害性对刀具监测系统提出了快速报警的要求。本文对切削振动信号在车刀破损时的变化规律进行了实验考察,提出了用均值分量的偏移和高频分量的短时消失来监测车刀破损的方法,并在已建立的微机监测系统中获得了满意的试验结果。

Based on the experiments, the characters of the signals of dynamic cutting force in a time domain at the moment of cutting tool breakage for producing metal fibre by chatter machining are discussed in this paper. It is proved that the variance σx2 and step relative coefficient ρ1 of a dynamic cutting force are sensitively changed and the σx2 and ρ1, increase with the growth of cutting tool breakage. Therefore, the σx2 of a dynamic cutting force is a satisfactory chara-cter as diagnosing the signal...

Based on the experiments, the characters of the signals of dynamic cutting force in a time domain at the moment of cutting tool breakage for producing metal fibre by chatter machining are discussed in this paper. It is proved that the variance σx2 and step relative coefficient ρ1 of a dynamic cutting force are sensitively changed and the σx2 and ρ1, increase with the growth of cutting tool breakage. Therefore, the σx2 of a dynamic cutting force is a satisfactory chara-cter as diagnosing the signal of cutting breakage. The experimental results also show that the filter is not needed by using the σx2 of the dynamic cutting sor-ce as a torecasting index of cutting toll breakage. Consequently, it is a simple and useful method to detect the cutting tool breakage.

本文在实验基础上,对颤振切削金属纤维碍的刀具研究了在不同破损状态下的动态切削力在时域中的特征,证实动态切削力的方差σ_x~2和一步相关系数ρ_1对刀具破损十分敏感,他们随刀具破损的加剧而增大,以σ_x~2作为判别刀具破损是一个满意的特征量。实验还证明,以它作为预报指标是不必设置滤波器的。

The on-line monitoring of tool wear and breakage is one of the basic functions of FMS. In this paper, a system for monitoring tool breakage by detecting the power of spindle motor is introduced. By processing the original power signal with dispersing autoregressive model AR, the difference between the measured value and the forecasting value of the model is used to judge the tool breakage.

刀具磨损、破损的在线监控是FMS的基本功能之一。本文介绍一种用检测主轴电机动率的方法来监测刀具破损的系统。功率原始信号经离散自回归AR模型处理,利用信号的实测值与模型预测值之间的预测偏差来判断刀具的破损。
