本文以不同的修整条件修整砂轮,用表面粗糙度仪测量砂轮表面轮廓曲线数据,通过FFT软件分析其频谱变化。实验结果表明,当修整深度较小时,砂轮表面出现明显的修整特征频率;当修整深度增大时,修整特征频率不明显。而修整进给率较小时,修整特征频率不明显;当修整进给率较大时,砂轮表面出现明显的修整特征频率。 In this paper, the grinding wheel is trimmed with different dressing conditions, and the profile data of the grinding wheel surface is measured with a surface roughness meter. The spectral changes of the grinding wheel are analyzed by FFT software. The experimental results show that when the dressing depth is small, the appearance frequency of dressing surface is obvious. When dressing depth increases, dressing frequency is not obvious. When the trimming feed rate is small, the trimming feature frequency is not obvious. When the trimming feed rate is larger, the trimming characteristic frequency of the grinding wheel appears obvious.
