中文摘要
在『製造自動化』發展潮流中,機械加工廠中加工刀具之崩刀以及磨耗的
自動檢測系統是相當重要的一環,其中又以崩刀為最嚴重、最緊急之事件
,必須立即檢知加以處理,否則工件不良品大量流入後方生產線,將造成
產品品質低落、信譽不良,並且增加品檢篩檢困難。因此發展出一種能夠
快速、可靠、且成本不高的線上刀具監測單晶片系統,取代落伍的人力檢
測方法,即是本論文所要研究之最終目的。
本論文深入研究車床刀具崩刀監測單晶化技術,期望建立一套單晶片系統
,根據周密的崩刀判斷法則,配合單晶片技術,而能實際低價地應用於工
業界,擺脫以往PC BASE的高成本。研究對象為東培工業公司之車削二課
T10 line外環密封板工程B車。
在論文中經由自行設計感測電路、前級放大電路、LPF電路、A/D電路
、8051單晶片數位電路、並且自行焊接電路板,然後根據崩刀研判法則撰
寫軟體程式,若自感測器蒐集的資料符合崩刀研判法則,則8051單晶片發
出訊號,透過PLC命令停機。實驗結果顯示,8051單晶片刀具監測系統能
在刀具崩刀發生後的三個工件內,將崩刀狀態成功檢出。

Abstract
The purpose of this thesis is to design a "on line tool
condition monitoring system using single chip microcomputer"for
detecting tool breakage during cutting process.It''s well known
that tool condition monitoring system plays an important role in
FMS system.By change the worn tool before or just at the same
time it fails,the loss of defect product can be reduced greatly
and thus improve product quality、reliability .
The 8051 tool monitoring system use strain gauge for measuring
cutting force,according to the force feature , tool monitoring
system can easily recognize the breakage of cutting tool with
tool breakage algorithm. The experimental result show that the
low cost 8051 tool monitoring board(about$9000) successfully
detect tool breakage in threee successive products .
