The resulting machining marks are, therefore, a helix having a very small pitch, which is equal to the feed. Consequently, the machined surface is always cylindrical.
所以，由此产生的机加工痕迹是一条具有很小节距的螺旋线，该节距等于进给。因此机加工表面始终是圆柱形的。
Great visual feed - back with semitone snap, and actual pitch indicator.
伟大的视觉饲料回半音管理单元，和实际音高的指标。
The stability and small dynamic errors could be confirmed by using the method of composite control in which the pitch angular rate of barbette sensed by INS was feed back and compensated in advance.
用复合控制把惯导系统测量的炮塔俯仰转动角速度（扰动角速度）反馈到控制前端，进行预先补偿，可保证小的瞬态误差和系统的稳定性。
