【摘要】 切削力的频谱特征与切削速度密切相关。本文利用频谱分析方法分析了不同切削速度下的切削力信号。结果表明,在不同切削速度下,切削力的功率谱存在若干特征频率,其幅值随着切削速度的减小而增大,可为切削监控提供依据。更多还原

【Abstract】 The frequency spectrum characteristics of the cutting forces have close relations with the cutting speed.The cutting force signals under different cutting speed conditions were analyzed by frequency spectrum analysis.The results indicate that there exists some characteristic frequency in cutting force power spectrum.The amplitudes increase as the cutting speed decreases which could be applied to the cutting process monitoring.更多还原
