基于PLC的精密切割数控车床的实现

本文提出了一种适用精密切割的数控车床设计方案。该方案采用机械触发式传感器，

通过控制车刀运动来触发传感器，PLC 把传感器得到的信号传给数控系统，再由系统来

进行相应的数据处理。机械触发式传感器与PLC 的输入扩展端的连接线简单，而且易于

维护，比用其它的传感器降低了成本。

Abstract:

This paper proposed one kind of CNC machine tool design proposal which is suitable

precisely cuts. This plan uses the machinery to touch the sensor, triggers the sensor through

the control lathe tool movement, and the PLC put the sensor signal to the CNC system, at last,

carries on the corresponding data processing by the system. The connected wired between

machinery sensor and the PLC is simple, moreover is easy to maintain, compared to other

sensors has reduced the cost.
