中 文 摘 要
在發展CNC工具機線上刀具監控系統時,必須要同時兼顧到成本與效益,才具有市場競爭力。
本研究採用無須添購其他感測器的方法,透過改寫CNC控制器內部的可程式控制(PMC)程式,以主軸馬達負載值輸出為依據,並且透過實驗找出馬達負載的知識法則(Rule),快速的對刀具的切削狀況做監控。
本研究所發展的系統應用於模具的粗切削中有良好的成效,有效地在刀具斷刀與過渡磨耗之前進行攔截,並以DNC連線方式送出換刀或停機NC Code,以避免造成更大的損失。
軟體友善的圖型化視窗介面,方便使用者操作,物件導向程式架構,可輕易的擴充程式功能。

Abstract
The development of on-line cutter monitoring system of CNC machine must give consideration to not only effect, but also cost.
In this paper, a low cost technique is developed to get the spindle motor load. With rewriting the PMC ladder diagram in CNC controller, need not any extra sensors. We can monitor cutting state rapidly by several knowledge rules, which defined by experiments.
The effect of the application in the monitoring system that established in this paper to the rough cutting of mold is excellent. When cutting tool breakage and wear, the system will effective to intercept mill process, and sent out change tool or stop NC code by DNC in order to avoid more damage.
A graphic user interface system is built to conduct the user friendly operation interface. Object Oriented Programming (OOP) framework can easily expand system capability.
