工作機械1は、工具を適宜交換しながらワークを所望の形状に加工するマシニングセンタとして構成されている。工作機械1は、装置筐体の内部にワークを加工する加工装置2を備える。装置筐体の前面には、加工装置2を操作するための操作盤4が設けられる。
工作機械1は、操作制御装置100、加工制御装置102、加工装置2、工具交換部104および工具格納部106を含む。加工制御装置102は、数値制御部として機能し、加工プログラム(NCプログラム)にしたがって加工装置2に制御信号を出力する。加工装置2は、加工制御装置102からの指示にしたがって工具主軸(図示略:以下、単に「主軸」という)を動かしてワークを加工する。
操作盤4は、オペレータに各種情報を表示するとともにタッチ操作を受け付けるモニタ50と、オペレータの操作入力を受け付ける物理的な操作パネル52を含む。モニタ50は、オペレータによるタッチ操作やキー入力等の操作入力を受け付ける各種操作画面を表示する「表示部」として機能する。モニタ50の表示画面150には、オペレータが参照および操作を行うための各種画面が表示される。後述の段取画面160は、その表示画面150全体の一部を占める。操作パネル52として、NC操作パネル54および機械操作パネル56が含まれる。
操作制御装置100の各構成要素は、CPU(Central Processing Unit)および各種コンピュータプロセッサなどの演算器、メモリやストレージといった記憶装置、それらを連結する有線または無線の通信線を含むハードウェアと、記憶装置に格納され、演算器に処理命令を供給するソフトウェアによって実現される。コンピュータプログラムは、デバイスドライバ、オペレーティングシステム、それらの上位層に位置する各種アプリケーションプログラム、また、これらのプログラムに共通機能を提供するライブラリによって構成されてもよい。以下に説明する各ブロックは、ハードウェア単位の構成ではなく、機能単位のブロックを示している。
図5および図6は、モニタ50の表示画面の一例を示す図である。
図5に示すように、モニタ50の表示画面150には、メイン画面表示領域152およびサブ画面表示領域154が設定されている。メイン画面表示領域152は、オペレータがメインで操作するメイン画面が表示される領域であり、表示画面150において大きな領域が設定される。図示の例では、メイン画面表示領域152として段取画面160が表示されている。段取画面160は、オペレータが段取り作業を行う際に操作する画面である。

工具設定部(T)は、工具に関する情報として、オペレータが工具交換の段取対象として指定する工具の識別情報を受け付ける。オペレータは、工具参照画面170に表示された工具一覧から工具を選択し、工具設定部(T)にその工具を指定する情報を入力することで、工具交換する工具を設定できる。この工具情報の入力は、工具設定部に工具番号(シリアル番号+グループ番号)又は工具名をキー入力(手動入力)することにより行うことができる。あるいは、工具一覧(複数の選択ボタン172)から交換対象の工具を選択し、図示略の取込ボタンを選択することで、工具設定部に工具番号が自動入力される。
主軸選択部は、オペレータが段取対象として指定する主軸の選択を受け付ける。オペレータは、主軸選択部のプルダウンメニューに表示される複数の主軸から回転させたい主軸を選択する。図示の例では、主軸S1が選択されている。このほか、プルダウンメニューに含まれる主軸S2,S3など(図示略)の選択も可能である。また、回転速度設定部は、主軸の回転速度に関する値の入力を受け付ける。オペレータは、回転速度設定部に数値を入力して主軸回転数を設定する。さらに、回転方向設定部のプルダウンメニューに表示される回転方向から正転又は逆転のいずれかを選択する。図示の例では、正転が選択されている。
(Mコード実行)
オペレータは、Mコード設定部にMコードをキー入力する。なお、Mコードは主軸の回転/停止、クーラントのON/OFF等の補助機能にかかる指令であるが、その詳細については説明を省略する。このようにMコード設定部にMコードが入力された状態でSTARTボタンが押下されると、制御指令部130が加工制御装置102に対して制御指令を出力する。その結果、該当するMコードが実行される。

図示の例では、メニュー表示部162の段取項目においてワーク計測が選択され、段取画面160としてワーク計測用段取画面が表示されている。工具計測の場合と同様に、詳細表示部164には、計測機能(ワーク計測の種類)の選択を受け付ける機能選択画面181が表示される。機能選択画面181は、計測一覧表示部182および特定計測表示部184を含む。図示の画面が、ワーク計測用段取画面のトップ画面である。
図13は、ワーク計測用段取画面の画面遷移を表す図である。
ワーク計測用段取画面を用いることにより、以下の手順でワーク計測を実行できる。なお、上述したモード選択ボタン60によりジョグモード(手動運転モード)に移行していることを前提とする。
表示制御部132は、段取画面160の表示中にメニュー表示部162における複数の段取項目の表示を保ちつつ、オペレータの操作入力に応じて詳細表示部164における操作画面の表示を切り替える。表示制御部132は、操作画面を切り替えつつ表示する過程でメニュー表示部162におけるいずれかの段取項目が選択された場合には、選択された段取項目に対応する操作画面のトップ画面を表示させる。
本処理は、オペレータによりメイン画面表示領域152に段取画面160が設定されることを契機に実行される。表示制御部132は、まず、先頭の段取画面のトップ画面を表示させる(S10)。本実施形態では、主軸操作用段取画面のトップ画面が表示される。
本実施形態によれば、段取画面160において固定された位置に各段取項目が常時表示されるため、オペレータがそれを認知しやすい。また、表示中の段取項目の種類や操作画面の階層にかかわらず、メニュー表示部162の段取項目を選択すれば、その段取項目のトップ画面を表示できる。このため、オペレータが段取項目を切り替える際に操作画面の階層を遡る等の煩雑な操作を削減できる。メニュー表示部162と詳細表示部164とが並べて表示され、いずれの段取項目を選択してもその選択後は詳細表示部164の操作画面のみを操作すればよいため、複数の段取項目に対して統一した操作感を実現できる。つまり、段取画面の操作についてオペレータの注意が散漫になることを抑制できる。その結果、段取り作業に用いる画面の操作性を向上できる。
図16は、変形例に係る工具計測用段取画面の画面遷移を表す図である。
本変形例では、オペレータにより機能選択画面181におけるいずれかの計測機能が選択されると(図16(A))、表示制御部132は、機能選択画面181を機能詳細画面293に切り替える。機能詳細画面293は、設定画面192と設定詳細画面295を含む。設定詳細画面295において工具参照画面170とガイダンス画面196とが切り替え可能に表示される(図16(B),(C))。本変形例では、機能選択画面181から機能詳細画面293に切り替えられたときに工具参照画面170が先に表示されるが、ガイダンス画面196が先に表示されるようにしてもよい。
本変形例では、設定画面168での入力が必須となる必須パラメータが設定される。具体的には、図17(A)に示すように、工具設定部(T)、主軸選択部、回転速度設定部およびMコード設定部のうち、工具設定部(T)が必須パラメータとされ、入力欄の横に必須であることを示すマーク「*」が表示されている。この必須パラメータへの入力がなされなければ、段取りのための運転(制御出力)を行うことができない。
この段取処理は、工作機械1の制御モードが特定モードであることを条件に実行される(S30のY)。本変形例の「特定モード」は、ジョグモードやハンドルモードなどの手動運転モードであり、予め設定される。表示制御部132は、まず、先頭の段取画面のトップ画面を表示させる(S32)。
本変形例では、ガイダンス表示などを経て段取を行ったあとに、工作機械を運転させるためにサイクルスタート(STARTボタンの押下)がなされる。ボタンが押されると、図19に示すように段取画面160が一種のインタロック状態となり、設定画面192の操作(各ボタンの選択やパラメータやデータの入力等)ができない状態になる(不可になる)。そして、運転が終了すると、つまり図19や図20では計測が終了すると、図20に示すように、設定画面192に計測結果199が示される。また、その運転の終了をもってインタロック状態が解除される。本変形例によれば、オペレータの操作入力により運転が指示されることで計測が開始され、そのまま結果が表示される。このため、スムーズな段取作業を実現できる。なお、本変形例では工具計測を例に挙げたが、ワーク計測や主軸操作や軸移動についても同様の構成を採用できることは言うまでもない。また、本変形例では運転は計測のための運転で説明しているが、加工の運転でも同様に流れになる。例えば、段取りが終わり、工作機械の加工の運転を開始させる場合に、サイクルスタートを行う。加工サイクルがスタートし加工が行われている間は、段取画面における各種入力や各種選択ができない状態(インタロック状態)になり、サイクルスタート前の入力値や選択内容を確認できるだけになる。加工が終了すると、加工結果が画面上に表示され、インタロック状態が解除される。
本変形例では、メニュー表示部162にも各段取項目を示す文字とアイコン画像とが表示される。例えば、図21の工具計測用のボタンには、「工具計測」との文字列と、工具計測を模式的に示したアイコン画像(図21は、長計測のアイコン画像)と、がボタン上に表示されている。メニュー表示部162の工具計測のボタンを選択すると、機能選択画面181が表示され、図21では長計測と径計測のボタンが表示され、ボタンの表面上にはそれぞれの計測内容が分かるアイコン画像が表示されている。図21では、機能選択画面181の特定計測表示部184(お気に入り画面)に表示されたいずれか計測のアイコン画像のボタンを選択すると、特定計測表示部184の下にガイダンス画面196が表示され、選択された計測を示すガイダンス(選択された計測の説明)が表示される。ガイダンスは、選択された計測の内容を説明する文と選択された計測がどのようなものか分かる動画や静止画とが表示されている。図21では、計測一覧表示部182(図10参照)がガイダンス画面196に切り替えられる形態だが、これに限定されるものではない。例えば、計測一覧表示部182に表示されている計測の種類を示すアイコン画像が表示されたボタンを押せば、選択さえたボタンの上にガイダンス画面196を表示する形態でもよい。いずれにしても本変形例によれば、選択された計測の種類とガイダンスを一画面で把握できる。
上記実施形態では、操作制御装置100を「表示制御装置」としても機能させる例を示した。すなわち、図4に示す構成を備える操作制御装置を「表示制御装置」の一形態として説明した。この表示制御装置は、オペレータの操作入力を直接受け付ける入力部を備えている。変形例においては、工作機械1と通信可能に接続された外部コンピュータを「表示制御装置」としても機能させてもよい。あるいは、工作機械において操作制御装置と通信可能に接続された内部コンピュータを「表示制御装置」としても機能させてもよい。表示制御装置は、「表示制御部」を備えるが「表示部」を備えないものでもよい。このような表示制御装置は、操作制御装置の操作入力部で受け付けたオペレータの操作入力に基づく情報(操作情報)を受け付ける入力部(受付部)を備えてもよい。表示制御装置は、一般的なラップトップPC(Personal Computer)あるいはタブレット・コンピュータであってもよい。
