表面粗糙度是摩擦学所有领域和评价加工质量的重要因素之一。为了实现柔性制造系统中的计算机控制加工，需要一种技术，用于在线，实时监测影响表面粗糙度的每个加工工艺参数。作为开发这种算法的第一步，本文报道了表面粗糙度和切削振动之间的相关性的研究。该算法利用刀具和工件之间的相对切削振动，这是通过一个电感传感器测量和过滤的模拟带通滤波器的特定振动分量。将特定频率的切削振动信号叠加到由刀具刃口半径和进给量计算的运动粗糙度上。实验结果表明，使用该算法获得的模拟粗糙度与表面轮廓仪实际测量的粗糙度之间具有良好的相关性。
Surface roughness is one of the important factors in all areas of tribology and in evaluating the quality of a machining operation. In order to achieve computer controlled machining in a flexible manufacturing system, a technique is needed for the on-line, real-time monitoring of each machining process parameter that affects surface roughness. As the first step in developing such an algorithm, research on the correlation between surface roughness and cutting vibration is reported in this paper. The algorithm utilizes the relative cutting vibrations between tool and workpiece, which are measured through an inductance pickup and filtered by an analog bandpass filter for a specific vibrational component. The cutting vibration signals of a specific frequency are superimposed onto the kinematic roughness, which is calculated by the tool edge radius and feed rate. Experimental results show good correlation between the simulated roughness obtained using the proposed algorithm and the roughness actually measured with a surface profilometer.
