　（動作シーケンス）
　図３Ａおよび図３Ｂは、情報処理装置２００を含むシステムの動作手順を示すシーケンス図である。図３Ａにおいて、まず、ステップＳ３０１において、情報処理装置２００としてのパス変更アプリが工作機械２１０にインストールされ起動される。 (operation sequence)
3A and 3B are sequence diagrams showing operation procedures of a system including the information processing apparatus 200. FIG. In FIG. 3A, first, in step S301, a path change application as the information processing device 200 is installed in the machine tool 210 and activated.
　情報処理装置２００のＣＬデータ取得部２０１は、ステップＳ３０３において、ＣＡＭ装置２５０から取得したＣＬファイルをパス変更アプリにインポートする。そして、ＣＬデータを表示画面生成部２０２およびＮＣプログラム生成部２０４に送る。ＮＣプログラム生成部２０４は、ステップＳ３０５において、ＣＬデータからＮＣプログラムを生成するためＣＬデータを保持する。 In step S303, the CL data acquisition unit 201 of the information processing device 200 imports the CL file acquired from the CAM device 250 into the path change application. Then, the CL data is sent to the display screen generator 202 and the NC program generator 204 . In step S305, the NC program generator 204 holds the CL data in order to generate the NC program from the CL data.
　表示画面生成部２０２は、ステップＳ３０７において、ＣＬデータに基づいてツールパスの一覧画面を生成して、ＨＭＩ２１１に送る。ＨＭＩ２１１は、ステップＳ３０９において、ツールパスの一覧画面を表示する。ＨＭＩ２１１においては、ユーザによる変更対象のツールパスの選択入力を待って、ツールパスの選択入力があるとステップＳ３１１において、ツールパスの選択入力を表示画面生成部２０２に返す。表示画面生成部２０２は、ステップＳ３１３において、選択されたツールパスが含むパラメータの設定画面を生成して、変更指示取得部２０３およびＨＭＩ２１１に送る。ＨＭＩ２１１は、ステップＳ３１７において、パラメータの設定画面から選択されたパラメータの設定値（変更値）の入力があれば、変更指示取得部２０３に送る。 The display screen generation unit 202 generates a tool path list screen based on the CL data and sends it to the HMI 211 in step S307. The HMI 211 displays a toolpath list screen in step S309. The HMI 211 waits for the selection input of the tool path to be changed by the user, and returns the selection input of the tool path to the display screen generation unit 202 in step S311 when there is the selection input of the tool path. The display screen generation unit 202 generates a parameter setting screen included in the selected toolpath and sends it to the change instruction acquisition unit 203 and the HMI 211 in step S313. In step S<b>317 , the HMI 211 sends the setting value (change value) of the parameter selected from the parameter setting screen to the change instruction obtaining unit 203 .
　変更指示取得部２０３は、ステップＳ３１９において、パラメータの設定値（変更値）の入力を取得し、ステップＳ３２１において、ＮＣプログラム生成部２０４にＣＬデータの変更を指示する。ＮＣプログラム生成部２０４は、ステップＳ３２３において、ＣＬデータの変更指示に対応してＣＬデータを変更する。 The change instruction acquisition unit 203 acquires the input of the parameter setting value (change value) in step S319, and instructs the NC program generation unit 204 to change the CL data in step S321. In step S323, the NC program generator 204 changes the CL data in response to the instruction to change the CL data.
　図３Ｂにおいて、表示画面生成部２０２は、ステップＳ３２５において、修正の対象となるツールパスの画面を生成して、変更指示取得部２０３およびＨＭＩ２１１に送る。ＨＭＩ２１１は、ステップＳ３２７において、ツールパスの画面を表示して、ユーザによる必要のないパスの検証を待つ。必要のないパスとは、例えば、ワークに工具が届いていない場合の切削パスなどである。ＨＭＩ２１１において、ユーザから必要のないパスが選択されると、ステップＳ３２９において、削除するパスの情報を変更指示取得部２０３に送る。変更指示取得部２０３は、ステップＳ３３１において、削除するパスを取得すると、ステップＳ３３３において、パスの削除に対応するＣＬデータの変更指示をＮＣプログラム生成部２０４に対して行う。ＮＣプログラム生成部２０４は、ステップＳ３３５において、ＣＬデータの変更指示に対応してＣＬデータを変更する。 In FIG. 3B, in step S325, the display screen generation unit 202 generates a screen of the tool path to be corrected, and sends it to the change instruction acquisition unit 203 and the HMI 211. In step S327, the HMI 211 displays the tool path screen and waits for verification of unnecessary paths by the user. An unnecessary pass is, for example, a cutting pass when the tool does not reach the workpiece. In HMI 211, when an unnecessary path is selected by the user, information on the path to be deleted is sent to change instruction acquisition section 203 in step S329. After acquiring the path to be deleted in step S331, the change instruction acquisition unit 203 instructs the NC program generation unit 204 to change the CL data corresponding to the deletion of the path in step S333. In step S335, the NC program generator 204 changes the CL data in response to the instruction to change the CL data.
　ＮＣプログラム生成部２０４は、ステップＳ３３７において、変更したＣＬデータに基づいて、ＮＣプログラムを生成して、工作処理部２１２に送る。工作処理部２１２は、ステップＳ３３９において、取得したＮＣプログラムにより工作機械を動作させ確認する。なお、ステップＳ３１３～Ｓ３２３の処理と、ステップＳ３２５～Ｓ３３５の処理とは、並列して実行される処理であっても、あるいは、逆の手順であってもよい。さらに、ステップＳ３２１およびＳ３２３の処理と、ステップＳ３３３およびＳ３３５の処理とは、パラメータ設定（変更）とパス削除との取得後に共通に実行されてもよい。 At step S337, the NC program generation unit 204 generates an NC program based on the changed CL data and sends it to the machining processing unit 212. In step S339, the machine tool processing unit 212 operates the machine tool according to the acquired NC program and confirms. The processing of steps S313 to S323 and the processing of steps S325 to S335 may be performed in parallel, or may be reversed.

FIG. 5 is a flow chart of processing procedures in the system of FIG. Among them, step S505 is the processing of the information processing apparatus 200 .
　ＣＡＭ装置２５０は、ステップＳ５０１において、ＣＡＭでパラメータを設定する。そして、ＣＡＭ装置２５０は、ステップＳ５０３において、ＣＡＭでＣＬデータを生成して出力する。 The CAM device 250 sets parameters with the CAM in step S501. Then, in step S503, the CAM device 250 generates and outputs CL data using the CAM.
　工作機械２１０では、情報処理装置２００が、ステップＳ５０５において、ユーザからの指示によりＣＬデータの変更（修正）をして、変更（修正）されたＣＬデータに基づいてＮＣプログラムを生成する。ステップＳ５０５は、工作機械上のパス変更アプリへＣＬデータをインポートするステップＳ５５１と、パス変更アプリでＣＬデータを設定（変更）するステップＳ５５３と、設定されたＣＬデータからＮＣプログラムを生成するステップＳ５５５と、を含む。 In the machine tool 210, in step S505, the information processing device 200 changes (corrects) the CL data according to an instruction from the user, and generates an NC program based on the changed (corrected) CL data.

　（情報処理装置の処理手順）
　図６Ａおよび図６Ｂは、図５のステップＳ５０５に対応する情報処理装置２００の処理手順を詳細に示すフローチャートである。なお、このフローチャートは、工作機械２１０あるいは情報処理装置２００が備えたＣＰＵがＲＡＭを使用して実行し、図２の情報処理装置２００の構成要素を実現する。 (Processing procedure of information processing device)
6A and 6B are flowcharts showing in detail the processing procedure of the information processing apparatus 200 corresponding to step S505 of FIG. This flowchart is executed by the machine tool 210 or the CPU provided in the information processing apparatus 200 using the RAM, and realizes the constituent elements of the information processing apparatus 200 in FIG.
　図６Ａにおいて、情報処理装置２００は、ステップＳ６０１において、ＣＡＭ装置２５０から取得したＣＬデータをインポートする。情報処理装置２００は、ステップＳ６０３において、ＣＬデータからツールパスの一覧画面を生成する。情報処理装置２００は、ステップＳ６０５において、ＨＭＩ２１１に、ツールパスの一覧表示を指示する。そして、情報処理装置２００は、ステップＳ６０７において、ＨＭＩ２１１からの、修正の対象とするツールパスの選択を待つ。ＨＭＩ２１１からツールパスの選択を受信すると、情報処理装置２００は、ステップＳ６０９において、対象となったツールパスのパラメータ設定画面を生成する。情報処理装置２００は、ステップＳ６１１において、ＨＭＩ２１１に、パラメータ設定画面の表示を指示する。また、情報処理装置２００は、ステップＳ６１３において、修正の対象となるツールパスの画面を生成して、ステップＳ６１５において、ＨＭＩ２１１に送って表示させる。 In FIG. 6A, the information processing device 200 imports the CL data acquired from the CAM device 250 in step S601. In step S603, the information processing apparatus 200 generates a toolpath list screen from the CL data. In step S605, the information processing apparatus 200 instructs the HMI 211 to display a list of tool paths. Then, in step S607, the information processing apparatus 200 waits for selection of a tool path to be corrected from the HMI 211. FIG. Upon receiving the toolpath selection from the HMI 211, the information processing apparatus 200 generates a parameter setting screen for the target toolpath in step S609. The information processing apparatus 200 instructs the HMI 211 to display a parameter setting screen in step S611. Further, the information processing apparatus 200 generates a screen of the tool path to be corrected in step S613, and sends it to the HMI 211 for display in step S615.
　図６Ｂにおいて、情報処理装置２００は、ステップＳ６１７において、ＨＭＩ２１１からの、修正の対象とするパラメータの選択か否かを判定する。ＨＭＩ２１１からのパラメータの選択を受信すると、情報処理装置２００は、ステップＳ６１９において、パラメータの変更値（修正値）の入力を待つ。ＨＭＩ２１１からパラメータの値を受信すると、情報処理装置２００は、ステップＳ６２１において、受信したパラメータの値に従って、ＣＬデータを変更する。 In FIG. 6B, in step S617, the information processing apparatus 200 determines whether or not a parameter to be corrected is selected from the HMI 211. Upon receiving the parameter selection from the HMI 211, the information processing apparatus 200 waits for input of a parameter change value (correction value) in step S619. Upon receiving the parameter value from the HMI 211, the information processing apparatus 200 changes the CL data according to the received parameter value in step S621.
　パラメータの選択でなければ、情報処理装置２００は、ステップＳ６２７において、ユーザによるＨＭＩ２１１からの削除するパスの選択入力か否かを判定する。削除するパスの選択入力があると、情報処理装置２００は、ステップＳ６２９において、パスの削除に従ったＣＬデータの変更を行う。なお、本実施形態では、不必要なパスの削除を説明したが、必要に応じてパスの追加もユーザの簡単な操作で同様に可能である。 If the input is not parameter selection, the information processing apparatus 200 determines in step S627 whether or not the user has input a path to be deleted from the HMI 211 . When there is an input for selecting a path to be deleted, the information processing apparatus 200 changes the CL data according to the deletion of the path in step S629. In this embodiment, deletion of unnecessary paths has been described, but paths can also be added by simple user operations as needed.
　そして、情報処理装置２００は、ステップＳ６２３において、変更したＣＬデータに基づいて、ＮＣプログラムを生成する。情報処理装置２００は、ステップＳ６２５において、工作処理部２１２に生成したＮＣプログラムを設定する。なお、ＣＬデータの変更がなければ、変更前のＣＬデータに基づいてＮＣプログラムを生成する。 Then, in step S623, the information processing apparatus 200 generates an NC program based on the changed CL data. The information processing apparatus 200 sets the generated NC program in the machining processing section 212 in step S625. If there is no change in the CL data, the NC program is generated based on the CL data before change.
　本実施形態によれば、ユーザによる、工作機械の表示画面に表示されたパラメータの簡単な設定やツールパス画像での削除などの操作により、工作機械でユーザが効率的にＣＬデータやＮＣプログラムを修正することができる。 According to the present embodiment, the user can efficiently transfer CL data and NC programs to the machine tool by performing operations such as simple setting of parameters displayed on the display screen of the machine tool and deletion in the tool path image. can be fixed.
　すなわち、切削パスを修正する場合は通常はＣＡＭ機能が必要だが、それ以外のパスの修正（削除）であればＣＡＭ機能は不要である。工作機械の実機動作確認の結果から、パスを修正したくなるケースは多く、実機上で簡単に加工パス修正ができるのは大きな利点となる。また、一般に、ＣＡＭ機能においては、３Ｄ形状からパスを計算し、大きなメモリや高性能のＣＰＵが必須となるため、実機上にＣＡＭ機能を搭載するのは困難である。これに対し、本実施形態は、単純なパスの修正に限定するため高負荷な演算を必要とせず、実機上に搭載されているＨＭＩなどの情報処理装置に搭載することが可能となる。 In other words, the CAM function is usually required for correcting cutting paths, but the CAM function is not required for correcting (deleting) other paths. There are many cases where we want to modify the path based on the results of the actual operation of the machine tool, and being able to easily modify the machining path on the actual machine is a great advantage. In general, the CAM function calculates a path from a 3D shape and requires a large memory and a high-performance CPU. On the other hand, since the present embodiment is limited to simple path correction, it does not require high-load calculations and can be installed in an information processing apparatus such as an HMI installed on an actual machine.

The user touches a path to be deleted from the toolpath image 811 with a finger 812 . In this example, an instruction is given to delete cutting paths in which the tool has not reached the workpiece (material). The lower diagram in FIG. 8 is a tool path image generated by the path deletion screen generation unit 224 and in which the indicated cutting path is deleted. Along with the display of the image after the cutting path is deleted, the CL data is changed corresponding to the tool path from which the cutting path is deleted, and the NC program is changed. In this embodiment, deletion of unnecessary paths has been described, but paths can also be added by simple user operations as needed.
　本実施形態によれば、他の実施形態の効果に加えて、工作機械の表示画面に表示されたツールパス画像から修正対象のパラメータを指示したり、削除対象の不必要なパスを指定したりできるので、工作機械でのユーザのより簡単な操作でツールパスのパラメータを変更（修正）することができる。 According to this embodiment, in addition to the effects of other embodiments, parameters to be corrected can be specified from the tool path image displayed on the display screen of the machine tool, and unnecessary paths to be deleted can be specified.
