The influence of feed movement of the nc machine on machining accuracy 数控机床进给运动对加工精度的影响
Resultant movement of feed 合成进给运动
Principal feed motion 主进给运动
Table feed motion 工作台进给运动
We should stand a higher level and take deeper consideration about some disturbs or some uncertain factors in situation of higher precision and tinier process . otherwise , zero mechanical gearing has nonsense 在要求高精度微进给的场合,必须站在更高的层次上,考虑更多的摄动与扰动等不确定因素对进给运动的影响,否则,零传动将失去原来所希望的意义。
