基于PLC的精密切割数控车床的实现

The Realization of the Precisely Cut CNC Machine Tool Based on PLC

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。

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.
