前記工作機械本体に付設され、前記ワークの加工に付随する所定の工程動作を実行する付設装置と、
前記工作機械本体に設けられた前記主軸装置、前記送り装置、及び前記加工補助装置、並びに、前記付設装置の作動を制御する制御装置と、
前記工作機械本体及び前記付設装置をNCプログラムに基づく自動運転より又は手動操作により作動させるための機械運転操作部を有し、該機械運転操作部の操作信号を前記制御装置に入力する主操作盤と、
前記付設装置を手動操作により作動させるための装置操作部を有し、該装置操作部の操作信号を前記制御装置に入力する副操作盤とを備えた工作機械であって、
前記副操作盤は、前記工作機械本体にて発生した所定異常を回避するための異常回避用動作を、前記工作機械本体に実行させるための異常回避操作部をさらに有していて、該異常回避操作部の操作信号を前記制御装置に入力するよう構成されており、
前記制御装置は、前記NCプログラムに基づく前記自動運転中に、前記副操作盤より前記異常回避操作部の操作信号を受信した場合には、前記工作機械の電源を遮断することなく、該操作信号に応じて、前記主軸装置、前記送り装置、及び前記加工補助装置の少なくとも一つの作動状態を変更することで前記異常回避用動作を実現可能に構成されている。
以下、本発明の具体的な実施形態について、図面を参照しながら説明する。
図1及び図2に示すように、本例の工作機械1は、立形のマシニングセンタであり、工作機械本体10、工具交換装置20、NC操作盤30、マガジン操作盤40及び制御装置100(図3参照)を備えている。
図3に示すように、前記制御装置100は、主制御部101、NCプログラム記憶部102、NCプログラム実行部103、送り制御部104、主軸制御部105、クーラント制御部106、工具交換制御部107、工具情報記憶部108及び表示制御部109を有している。
図3及び図4に示すように、NC操作盤30は、表示部31、NC入力操作部32、及び機械運転操作部33を備えている。
図3及び図5に示すように、前記マガジン操作盤40は、表示部41、マガジン操作部42、異常回避操作部43、及び優先モードボタン44を有している。マガジン操作盤40は、その操作面がスプラッシュガードGから外部に露出するように配置されている(図1び図2参照)。マガジン操作盤40は、図2において、工具マガジン21を覆うカバー体25に形成された開口部25aの左側に配置されている。図2において開口部25aの紙面手前側は、オペレータが工具Tの着脱作業を行うための作業位置であり、マガジン操作盤40はこの作業位置に隣接して配置されている。
次に、主制御部101において優先操作モードの設定及び解除に伴って実行されるオーバーライド値の決定処理を説明する。
以上のように構成された工作機械1において、オペレータが工具交換装置20の工具マガジン21にて段取り作業(工具Tの着脱作業)を行う際には、先ず、マガジン操作盤40の段取りモード設定ボタン42aを操作して、工具交換装置20を段取りモードに設定する。そして、オペレータは、マガジン操作盤40の工具呼出しキー42b及びマガジン駆動ボタン42cを操作して、作業対象の工具ポット22を工具着脱位置に呼び出す。そして、オペレータは、工具ポット22に取付けられた摩耗した工具T交換したり、加工ワークの機種変更に備えて工具ポット22に異なる工具Tを装着する等の作業を行う。
図6は、前記実施形態の変形例を示す図5相当図である。この変形例では、マガジン操作盤40の異常回避操作部43の構成が前記実施形態とは異なっている。尚、図6において、図5と同じ構成部分には同じ符号を付してその詳細な説明を省略する。
前記実施形態及び変形例では、マガジン操作盤40にて優先操作モードが設定されている場合に、マガジン操作盤40の異常回避操作部43とNC操作盤30とで相容れない操作が同時に実行されたときには、NC操作盤30の操作を無視してマガジン操作盤40の異常回避操作部43の操作を優先するようにしているが、これに限ったものではない。例えば、優先操作モードを、マガジン操作盤40の異常回避操作部43の操作を有効化するためだけのモードと位置づけて、前記相容れない操作がなされた場合にマガジン操作盤40の異常回避操作部43とNC操作盤30とのいずれの操作を優先するかについては、予め定めた優先操作条件に基づいて判断するようにしてもよい。
