speed of spindle meaning in English

轴速
轴转速

To keep constant cutting angle and speed , a method with tool swinging and variable - speed of spindle is presented
为了解决上述问题，本文提出了刀具摆动与主轴变转速的凸轮车削加工方法，以实现恒角度与恒速度切削。
The polar coordinates of tool swinging pivot are figured out , and the expressions of tool swinging and the variable - speed of spindle are derived
通过对凸轮车削的运动关系进行分析计算，推导出在恒角度与恒速度切削的情况下，刀具摆角、机床主轴转速与凸轮转角位置的关系，为在实际中应用提供了理论依据。
