摘　　要：数控机床回参考点的准确性,不但影响机床的稳定性,更重要的还影响加工精度及加工尺寸的稳定性。笔者通过数控机床返回参考点的原理,结合具体事例,分析了数控机床回参考点故障诊断的一般方法,并提出了对加工中心机床换刀点的改进意见。数控机床回参考点的故障分析是在其确定了回参考点方式下准确诊断出来的,并加以及时排除,从而进一步提高了数控机床的开动率和可靠性。NC machine tool returning reference point by rule and line, Affect stability of machine, And that, Affect precision of machine. The text research the principle of returning reference point for NC machine tool, Through analysis and examples, Analyze malfunction diagnosis of returning reference point for NC machine tool, And bring forward amelioration for ATC of machine center. Only when the trouble of reference point on NC machine tool is accurately diagnosed under the way of determining the reference point, It can be further improved the boot-strap operating ratio and reliabilitv of NC machine tool.
