摘要

本文介绍了利用传声器作为可听声音传感器来监测具有研磨运动学的单面磨削过程。磨削时产生的可听声音取决于D107金刚石颗粒和不同镍结合层厚度的电镀刀具的切削性能。刀具磨损影响了材料去除率和陶瓷样品表面粗糙度等工艺效果。表征声音信号的数量与加工表面的表面粗糙度之间的关系通过使用声音信号的频谱分析在频域进行了检查，重点是Ra参数。减小幅度表明表面光洁度较好，Ra = 0.23µm。所开发的方法和得到的结果将有利于电镀刀具在研磨工艺中的实际应用，在获得所需表面粗糙度之前不会中断加工过程。

Method of monitoring of the grinding process with lapping kinematics using audible sound analysis

Utilising microphones as audible sound sensors for monitoring a single-side grinding process with lapping kinematics is presented in the paper. The audible sound generated during grinding depended on the cutting properties of electroplated tools with D107 diamond grains and different thicknesses of the nickel bond. The tool wear affected the obtained technological effects such as material removal rate and the surface roughness of Al 2 O 3 ceramic samples. The relationship between the quantities that characterise the sound signal and the surface roughness of machined surfaces was examined with the use of spectral analysis of the sound signal in the frequency domain with a focus on the Ra parameter. The decreasing amplitude indicated a better surface finish, down to Ra = 0.23 µm. The developed method and the obtained results will facilitate the practical use of the electroplated tools in the lap-grinding technology without interrupting the process before obtaining the required surface roughness.
