磨削加工中砂轮对刀技术概述及声发射应用试验研究
Tool setting methods in grinding process and application of acoustic emission technology
摘要
Abstract
As an important part in the grinding process , a variety of tool setting methods and their characteristics were presented , such as the methods based on manual operation , tool setting gauge , resistance , conductivity , acoustic emission ( AE) . Furthermore , a series of experiments were carried out to study the application of AE technology under different grinding conditions . The results demonstrated that acoustic emission could be applied to tool setting in both dressing and grinding process , as the waveform , spectrum distribution , waveform parameters of acoustic emission signals reflected the tool setting states responsively . However , acoustic emission signals might be easily affected by background noise in the grinder . The SNR ( signal to noise ratio) of tool setting in grinding was higher than that in dressing when the AE tests were conducted in the same grinder . Furthermore , compared with the CNC grinder , the common grinder could gain a higher SNR in dressing .关键词
