| Abstract: | It is critical in tool state monitoring research area to develop sensors with high sensitivity to tool wear, easy to install and having strong resistance to interference. Enlightened by the typical structures of the low sound sensors with press difference used in the air acoustics, complied to the requirements of the automatic metal cutting process, a new kind of non-contact metal-ceramic fluid acoustic emission (AE) sensor with high sensitivity to the cutting tool wear is developed. The experiment results showed that the sensor has high sensitivity to tool wear AE signal. |
