本文提出了一種適用精密切割的數(shù)控車床設(shè)計(jì)方案。該方案采用機(jī)械觸發(fā)式傳感器，
通過(guò)控制車刀運(yùn)動(dòng)來(lái)觸發(fā)傳感器，PLC 把傳感器得到的信號(hào)傳給數(shù)控系統(tǒng)，再由系統(tǒng)來(lái)
進(jìn)行相應(yīng)的數(shù)據(jù)處理。機(jī)械觸發(fā)式傳感器與PLC 的輸入擴(kuò)展端的連接線簡(jiǎn)單，而且易于
維護(hù)，比用其它的傳感器降低了成本。

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.
