刀具状态在线监测与智能识别方法研究

切削加工中刀具状态是影响加工质量的关键因素,刀具的磨损直接影响工件的加工精度和表面粗糙度.选择加速度传感器监测切削加工中的振动信号,针对刀具状态变化时振动能量分布随之变化的特点,提取不同频段振动能量作为特征量,利用RBF神经网络进行聚类辨识.实验结果表明,该方法具有良好的识别效果和工程应用价值.

Research on Online Monitoring and Intelligent Recognition of Tool Condition

Tool condition is the key factor to affect the machining quality.The wear of cutting tool directly influences the machining accuracy and surface roughness of the workpiece.The acceleration sensor is used to monitor the machining vibration of cutting process.According to the change of energy distribution of vibration signals,the energy distribution of different frequency bands are extracted,and then RBF neural network is used to identify the cutting tool condition.Experimental results show that this approach has good recognition effect and engineering application value.
