Description
本発明は、運転中に加工プログラムの修正、追加または削除が可能な工作機械に関する。
The present invention relates to a machine tool capable of correcting, adding or deleting a machining program during operation.
制御装置（ＮＣ装置等）を搭載している工作機械は一般的に、制御装置（ＮＣ装置等）の持つ加工プログラムの保存領域に予め加工プログラムを保存しておくことができる。そして、保存した加工プログラムを先頭から最後まで実行し、機械軸を動作させ、目的の加工をおこなうことができる（例えば、特許文献１参照）。
In general, a machine tool equipped with a control device (NC device or the like) can store a machining program in advance in a machining program storage area of the control device (NC device or the like). Then, the stored machining program is executed from the beginning to the end, the machine shaft is operated, and the desired machining can be performed (for example, see Patent Document 1).
工作機械を利用して加工をおこなう場合において、制御装置（ＮＣ装置）の持つ加工プログラムの保存領域に保存された加工プログラムを実行している途中で、その加工プログラムの未実行部分を修正したり、その加工プログラムの最終行の後ろにさらに加工プログラムを追加したり、削除したいという要求がある。
When machining using a machine tool, correct the unexecuted part of the machining program while executing the machining program saved in the machining program storage area of the control unit (NC device). There is a demand to add or delete a machining program after the last line of the machining program.
しかし、加工プログラムの実行中に加工プログラムを編集（修正、追加または削除）しようとすると、編集（修正、追加または削除）途中に加工プログラムが編集（修正、追加または削除）箇所に到達してしまう可能性があることがから、加工プログラムの実行中に加工プログラムを編集（修正、追加または削除）することは通常不可能である。
However, if you attempt to edit (modify, add or delete) a machining program while the machining program is running, the machining program reaches the edit (modify, add or delete) location during editing (modify, add or delete). Because of the possibilities, it is usually impossible to edit (modify, add or delete) a machining program during execution of the machining program.
以上の理由から、従来では以下のようにおこなっている。
For the above reasons, the conventional method is as follows.
（１）すでに実行し始めてしまった加工プログラムの未実行部分を修正したい場合は、途中で実行を止めて加工プログラムを修正し、加工プログラムを明らかに実行が終わっているところから、あるいは最初からスタートさせなければならない。加工時間が長いものは１００時間以上におよぶ場合もあり、この場合、途中で実行を止めて最初からやり直すのは数十時間以上のロスになることもある。
(1) If you want to correct an unexecuted part of a machining program that has already begun to be executed, stop the execution and modify the machining program, and start from the point where the machining program has been clearly executed or from the beginning. I have to let it. In some cases, the processing time is longer than 100 hours, and in this case, it may be a loss of several tens of hours or more if the execution is stopped halfway and started again from the beginning.
（２）すでに実行し始めてしまった加工プログラムの後ろにさらに加工プログラムを追加したい場合は、現在の加工が終了するまで待ってから追加の加工プログラムを保存し、実行しなければならない。この時、現在の加工プログラムの終了が深夜であったり週末であったりすると、翌日などに加工オペレータが出勤するまで加工がストップしてしまい、これも数時間～数十時間のロスになってしまう。
(2) If you want to add a machining program after a machining program that has already begun to be executed, you must wait for the current machining to finish before saving and running the additional machining program. At this time, if the current machining program ends at midnight or on a weekend, the machining will stop until the machining operator goes to work the next day, etc., which will also result in a loss of several hours to several tens of hours. .
（３）すでに実行し始めてしまった加工プログラムの未実行の加工プログラムの一部が不要になり削除したい場合は、ちょうどよいところで加工プログラムを中止できればよいが現実的に難しい。従って、加工プログラムの一部が不要と判断した時点で実行を止めて加工プログラムの一部を削除し、プログラムを明らかに実行が終わっているところから、あるいは最初からスタートさせなければならない。この場合、途中で実行を止めて最初からやり直すのは数十時間以上のロスになることもある。
(3) If a part of an unexecuted machining program of a machining program that has already started to be executed becomes unnecessary and it is desired to delete it, it is only difficult to stop the machining program at the right place, but it is practically difficult. Therefore, when it is determined that a part of the machining program is unnecessary, the execution is stopped, a part of the machining program is deleted, and the program must be started from the point where the execution is clearly finished or from the beginning. In this case, stopping execution halfway and starting over from the beginning may result in a loss of tens of hours or more.
本発明は、加工プログラムの実行中に加工プログラムを変更することで、加工プログラムの修正のために加工を中止することを防ぎ、加工時間のロスをなくすことを目的とする。
The present invention has an object to prevent the machining time from being lost by changing the machining program during execution of the machining program, thereby preventing the machining from being stopped for the modification of the machining program.
また、加工プログラムの実行中に加工プログラムを追加することで、加工オペレータの不在時に加工が終了し機械が停止することを防ぎ、加工時間のロスをなくすことを目的とする。
Also, by adding a machining program during execution of the machining program, it is intended to prevent the machining from being stopped and the machine from stopping when the machining operator is absent, thereby eliminating machining time loss.
さらに、加工プログラムの実行中に加工プログラムを削除することで、加工プログラムの削除のために加工を中止することを防ぎ、加工時間のロスをなくすことを目的とする。
Furthermore, by deleting the machining program during execution of the machining program, it is intended to prevent the machining from being stopped due to the deletion of the machining program and to eliminate the loss of machining time.
上記課題を解決するために、本発明は、加工プログラムに基づきワーク加工を行う工作機械において、工作機械の運転中に前記加工プログラムの編集を行う編集手段と、前記加工プログラムの実行を待機させる待機手段とを備え、前記編集手段による編集を認識した場合に、前記待機手段が前記加工プログラムの実行を待機させることを特徴とする。
In order to solve the above-described problems, the present invention provides a machine tool that performs workpiece machining based on a machining program, an editing unit that edits the machining program during operation of the machine tool, and a standby that waits for execution of the machining program. Means for waiting for execution of the machining program when the editing by the editing means is recognized.
本発明の他の特徴は、前記編集手段が、前記加工プログラムに対する修正、追加または削除を実行することである。
Another feature of the present invention is that the editing means executes correction, addition or deletion to the machining program.
本発明の他の特徴は、工作機械の制御装置（ＮＣ装置等）の外部領域に前記加工プログラムを保存することである。
Another feature of the present invention is that the machining program is stored in an external area of a machine tool control device (NC device or the like).
本発明の他の特徴は、工作機械の外の演算装置（パソコン等）に前記加工プログラムを保存することである。
Another feature of the present invention is that the machining program is stored in an arithmetic device (such as a personal computer) outside the machine tool.
本発明の他の特徴は、前記加工プログラムが複数の加工プログラムからなり、前記複数の加工プログラムの各加工プログラムの実行後に、変更中チェックプログラムが実行され、前記変更中チェックプログラムにより、現在実行中のプログラムの次の加工プログラムが編集中であることが判明した場合、前記待機手段が前記加工プログラムの実行を待機させることである。
Another feature of the present invention is that the machining program includes a plurality of machining programs, and a check program that is being changed is executed after execution of each machining program of the plurality of machining programs, and is currently being executed by the check program that is being changed. When it is found that the next machining program of the program is being edited, the waiting means waits for the execution of the machining program.

また、本実施形態では、工作機械Ａの運転中に加工プログラムの編集をコンピュータ１が行い、加工プログラムの実行の待機をＮＣ装置Ｃのコンピュータが行うようになっているが、工作機械Ａの運転中に加工プログラムの編集および加工プログラムの実行の待機をＮＣ装置Ｃのコンピュータのみで行うようにしても良い。
In this embodiment, the computer 1 edits the machining program during the operation of the machine tool A, and the computer of the NC apparatus C waits for the execution of the machining program. The machining program editing and the machining program execution standby may be performed only by the computer of the NC apparatus C.
編集手段による編集を認識した場合に、待機手段が加工プログラムの実行を待機する。編集手段は、加工プログラムに対する修正、追加または削除を実行する。
When the editing unit recognizes editing, the standby unit waits for execution of the machining program. The editing means executes correction, addition or deletion with respect to the machining program.
加工プログラムは例えばＮＣプログラム（数値制御プログラム）のようなもので、各動作等の命令が実行順に並んでいる。
The machining program is an NC program (numerical control program), for example, and instructions for each operation are arranged in the order of execution.
事前準備として、加工プログラムは分割できる単位で分割しておく（ここではｃ個に分割したとする）。

The processing from step SA01 to step SA03 is executed each time when it is recognized whether correction, addition or deletion is in progress, as will be described in a specific example described later.
次に、変更チェック処理の具体例の説明を行う。
Next, a specific example of the change check process will be described.
以下の説明では、図４に示すように、「加工プログラム１」、「加工プログラム２」、「加工プログラムａ-1」を実行し、現時点では「加工プログラムａ」が実行中であるとする。
In the following explanation, as shown in FIG. 4, it is assumed that “machining program 1”, “machining program 2”, and “machining program a-1” are executed, and that “machining program a” is currently being executed.
図５を参照する。ケース１として、加工プログラムを変更（編集）する場合を説明する。
Refer to FIG. As case 1, a case where the machining program is changed (edited) will be described.
「加工プログラムａ」を実行中に、未実行の加工プログラムを変更したい状況となったとする。この場合には、制御ソフトウェアＢが加工プログラムの変更をおこなう。ここではたとえば、「加工プログラムｂ＋１」～「加工プログラムｃ」を変更する例を示す。実際には、「加工プログラムｂ＋１」～「加工プログラムｃ」の中の特定のいくつかの加工プログラムを変更することもある。
Suppose that you want to change an unexecuted machining program while executing “Machining program a”. In this case, the control software B changes the machining program. Here, for example, “machining program b + 1” to “machining program c” are changed. In practice, some specific machining programs in the “machining program b + 1” to “machining program c” may be changed.
図６を参照する。加工プログラムの変更中に、加工プログラムｂが終了した場合について説明する。
Refer to FIG. A case where the machining program b is terminated while the machining program is changed will be described.
制御ソフトウェアＢが「加工プログラムｂ＋１」～「加工プログラムｃ」を変更している途中で加工プログラムが進み加工プログラムｂが終了した場合に、変更途中の加工プログラムの実行がされないように以下のように処理される。
When the control program B changes the “machining program b + 1” to “machining program c” and the machining program advances and the machining program b ends, the machining program being changed is not executed as follows. It is processed.
「加工プログラムｂ」の後の「変更中チェックプログラムｃｐ」が制御ソフトウェアＢに問い合わせ、次の加工プログラムｂ＋１の変更処理中であれば次の「加工プログラムｂ＋１」に進まずに待機する。
“The checking program cp” after “machining program b” makes an inquiry to the control software B. If the next machining program b + 1 is being changed, the process waits without proceeding to the next “machining program b + 1”.
加工プログラムの変更処理が終了したら、「変更中チェックプログラムｃｐ」も終了し、「加工プログラムｂ＋１」に進む。「変更中チェックプログラムｃｐ」では上述のステップＳＡ０１～ステップＳＡ０３が実行される。
When the machining program change processing is completed, the “during-change check program cp” is also terminated, and the process proceeds to “machining program b + 1”. In the “in-change check program cp”, the above-described steps SA01 to SA03 are executed.
図７を参照する。ケース２として、加工プログラムを追加（編集）する場合を説明する。「加工プログラムａ」を実行中に、加工プログラムを追加したい状況となったとする。この場合には、制御ソフトウェアＢが加工プログラムの追加をおこなう。ここではたとえば、「加工プログラムｃ」の後ろに、「加工プログラムｃ＋１」～「加工プログラムｄ」および追加したそれぞれの加工プログラムの後の変更中チェックプログラムを追加する例を示す。
Refer to FIG. As case 2, a case where a machining program is added (edited) will be described. Assume that a situation in which a machining program is desired to be added during execution of “machining program a”. In this case, the control software B adds a machining program. Here, for example, “machining program c + 1” to “machining program d” and a checking program for changing after each added machining program are added after “machining program c”.
図８を参照する。加工プログラムの追加中に、加工プログラムｃが終了した場合、すなわち、制御ソフトウェアＢが「加工プログラムｃ＋１」～「加工プログラムｄ」を追加している途中で加工プログラムが進み加工プログラムｃが終了した場合に、追加途中の加工プログラムの実行がされないように以下のように処理される。
Refer to FIG. When the machining program c ends while the machining program is added, that is, when the machining program advances and the machining program c ends while the control software B is adding “machining program c + 1” to “machining program d”. In addition, the following processing is performed so that the machining program being added is not executed.
「加工プログラムｃ」の後の「変更中チェックプログラム」が制御ソフトウェアＢに問い合わせ、加工プログラムの追加処理中であれば次の「加工プログラムｃ＋１」に進まずに待機する。
“The checking program being changed” after the “machining program c” inquires the control software B. If the machining program is being added, the process waits without proceeding to the next “machining program c + 1”.
加工プログラムの変更処理が終了したら、「変更中チェックプログラムｃｐ」も終了し、「加工プログラムｃ＋１」に進む。「変更中チェックプログラムｃｐ」ではステップＳＡ０１～ステップＳＡ０３が実行される。
When the machining program change processing is completed, the “during-change check program cp” is also terminated, and the process proceeds to “machining program c + 1”. In the “in-change check program cp”, steps SA01 to SA03 are executed.
図９を参照する。ケース３は、加工プログラムを削除（編集）する場合である。「加工プログラムａ」を実行中に、未実行の加工プログラムの一部を削除したい状況となったとする。この場合には、制御ソフトウェアＢが加工プログラムの削除をおこなう。
Refer to FIG. Case 3 is a case where the machining program is deleted (edited). It is assumed that it becomes a situation where it is desired to delete a part of the unexecuted machining program while executing the “machining program a”. In this case, the control software B deletes the machining program.
ここでは、たとえば、「加工プログラムｂ＋１」～「加工プログラムｃ」およびそれぞれの加工プログラムの後の変更中チェックプログラムｃｐを削除する例を示す。実際には、「加工プログラムｂ＋１」～「加工プログラムｃ」のすべてではなく、その中の特定のいくつかの加工プログラムを削除することもある。
Here, for example, “machining program b + 1” to “machining program c” and an in-change check program cp after each machining program are deleted. Actually, not all of “machining program b + 1” to “machining program c”, but some specific machining programs may be deleted.
図１０を参照する。加工プログラムの削除中に、加工プログラムｂが終了した場合、すなわち、制御ソフトウェアＢが「加工プログラムｂ＋１」～「加工プログラムｃ」を削除している途中で加工プログラムが進み加工プログラムｂが終了した場合に、削除途中の加工プログラムの実行がされないように以下のように処理される。
Refer to FIG. When the machining program b ends while the machining program is deleted, that is, when the machining program advances and the machining program b ends while the control software B deletes “machining program b + 1” to “machining program c”. In addition, the following processing is performed so that the machining program being deleted is not executed.
「加工プログラムｂ」の後の「変更中チェックプログラムｃｐ」が制御ソフトウェアＢに問い合わせ、加工プログラムの削除処理中であれば次の「加工プログラムｂ＋１」に進まずに待機する。変更中チェックプログラムｃｐではステップＳＡ０１～ステップＳＡ０３の処理が実行される。
“The checking program cp” after “machining program b” makes an inquiry to the control software B. If the machining program is being deleted, the process waits without proceeding to the next “machining program b + 1”. In the changing check program cp, the processes of steps SA01 to SA03 are executed.
加工プログラムの削除処理が終了したら、「変更中チェックプログラムｃｐ」も終了し、加工が終了する。ただし、その先に「加工プログラムｃ＋１」などが続く場合は加工プログラムの実行が続く。
When the processing program deletion process is completed, the “in-change check program cp” is also ended, and the processing ends. However, if the “machining program c + 1” or the like follows, the machining program continues to be executed.
図１１を参照する。加工プログラムおよび変更中チェックプログラムｃｐをＮＣ装置Ｃの外にあるコンピュータ１における「加工プログラム保存装置Ｆ」の「加工プログラム外部保存領域Ｇ」に保存する場合について示す。「加工プログラム保存装置Ｆ」の「加工プログラム外部保存領域Ｇ」は、例えばＵＳＢメモリのようなものであってもよい。
