进一步分析表明，能耗不能降低的原因仍然是因为转速被稳定在最低转速下运行所致。
Further analysis shows that the reasons for reducing energy consumption can not continue because the speed was stable in operation due to the minimum speed.
结果表明，连续改变机床主轴转速时振动响应的最低点即为不发生颤振的稳定切削点。
The results show that the vibrational response varies regularly when the spindle speed is continuously changed from low to high.
结果表明，连续改变机床主轴转速时振动响应的最低点即为不发生颤振的稳定切削点。
The results show that the vibrational response varies regularly when the spindle speed is continuously changed from low to high. The lowest point of the response is the stable cutting point.
