摘要
针对螺纹硬旋铣过程中刀具振动状态的辨识问题开展试验研究。根据硬旋铣的工艺特点设计刀齿切削力监测系统及切削试验,对切削力数据进行频域分析。研究结果表明:硬旋铣机床的刀具切削振动是由断续切削引起的强迫振动无自激振动发生的。
The experimental investigation of identifying tool vibration status in hard whirling process is undertaken.According to the technologic features of hard whirling,a measure system to monitor the triaxial cutting forces of individual cutter is developed,cutting tests are conducted,and the frequency analysis on cutting force data is completed.The results show that the cutting vibrations of hard-whirling cutters are caused by the forced vibrations due to interrupted cutting without any self-excited vibrations.
