This paper proposes an interpolation algorithm that confines the chord error within a specified tolerance range during the interpolation process by adjusting the feedrate.

作者提出了一种数控机床在插补过程中通过调整进给速度从而将弦差限定在一定的误差范围内的插补算法。

Other causes include the out - of - tolerance of blade chord width between adjacent blades, the undersize contact area of serrated working side and the local wearing of non - working side.

而相邻原机件叶片弦宽尺寸超差，锯齿形工作接触面积小，以及非工作面局部碰磨，是引发故障的次要因素。
