刀具磨损和破损的综合监测法 总被引:5,自引:0,他引:5
简述一种监测刀具磨损和破损的方法——参考量综合监测法,并设计了监测线路。由于采用该方法时能对电网电压进行监测,自动减去首切电流,还用声发射(AE)、电机电流综合对刀具磨损和破损进行判别,所以拓宽了监测范围,提高了抗干扰能力,使该监测系统具有较高的判别成功率。 相似文献

金属切削刀具的磨损和损坏直接影响到加工质量,因此有必要在生产实践中对刀具进行实时监控。刀具磨损或损坏时,切削力会发生变化,主轴电动机负荷也会发生变化,因此,可以根据主轴电动机负荷判断切削刀具是否到达寿命。本文探索了一种在数控机妹上通过监视主轴电动机负荷实时监控刀具寿命的方法,并给出了具体的实现技术及PLC和CNC程序。 相似文献

One of the most important research topics in the area of Intelligent Manufacture Systems (IMS) is the automatic detection of tool breakage, wear of chipping during the cutting process. Sensor-based techniques are available for cutting force measurements, but there are drawbacks in this approach in cost and idle times. This work proposes a sensorless monitoring system for tool monitoring in order to detect breakage and chipping by exploiting the wavelet transform and a neural network. Previous works have made use of these tools for monitoring several machining parameters, but we propose an integrated low-cost approach to detect quickly the changes in the tool integrity for monitoring. The system output produces an accurate detection of the tool integrity that enables the system to prevent damage due to tool breakage. This approach allows for an industrial solution to be developed. 相似文献
