虽然各种数控机床的功能和应用各不相同，但它们有着共同的优点。这里是数控设备提供的比较重要的几个优点。
各种数控机床的第一个优点是自动化程度提高了。零件制造过程中的认为干预减少或者免除了。整个加工循环中，很多数控机床处于无人照看的状态，这使操作人员被解放出来，可以干别的工作。数控机床用户得到的几个额外好处是：数控机床减小了操作人员的疲劳程度，减少了人为误差，工件加工时间一致而且可预测。由于机床在程序的控制下运行，与操作普通机床的机械师要求的技能相比，对数控操作员的技能要求也降低了。
While the specific intenion and applicaion for CNC machines vary from one machine tape to another ,all forms of CNC have common benefits .here are but a few of the more important benefits offered by CNC equipment.
The first benefit offered by all forms of CNC machine tools is improved autemation .The operator intervention related to producing workpieces can be reduced or eliminated .many CNC machines can run unattended during their entire machining cycle,freeing the operator to do oher tasks.Tish gives the CNC user several side benefits including reduced operator
