摘要
针对现有的刀头磨损检测方法检测难度大、无法实时监测的缺点,提出一种基于光纤布拉格光栅(FBG)阵列的刀具磨损检测新方法。在实验上搭建了多路光纤光栅磨损检测系统,通过对光纤光栅的定位和波分复用能力进行分析,得到了可应用于刀头磨损检测领域的嵌入式光学传感器,将4根栅区长度为3 mm的FBG阵列等间隔分立布置,并同时进行解调。利用该方法实现了对磨损长度的在线实时监测,磨损检测误差在0.23 mm以内。
Abstract
To address the shortcomings of the current cutter wear detection methods which have difficulty to detect in real time, a new method based on the fiber Bragg grating (FBG) array for cutter wear detection is proposed. A multi-channel FBG wear detection system is built experimentally. By analyzing the positioning and wavelength division multiplexing capabilities of FBG, an embedded optical fiber sensor which can be used in cutter wear detection field is obtained. Four FBG arrays with 3 mm grating length are arranged separately with equal interval and demodulated simultaneously. The online real-time monitoring of wear length is realized, and the wear detection error is less than 0.23 mm.
