　情報処理装置２００は、ＮＣシミュレータであり、ＣＡＭ２４０が生成した加工プログラムとしてのＮＣプログラム２３０に応じて加工シミュレーションを行い、数値制御装置２２０で用いられる加工プログラムとしてのＮＣプログラム２３０を更新する。情報処理装置２００は、ＮＣシミュレーション部２０１と、判定部２０２と、ＮＣプログラム更新部２０３とを含む。 The information processing device 200 is an NC simulator, performs machining simulation according to the NC program 230 as the machining program generated by the CAM 240, and updates the NC program 230 as the machining program used in the numerical controller 220. Information processing apparatus 200 includes NC simulation section 201 , determination section 202 , and NC program update section 203 .
　ＣＡＭ２４０は、メインプロセッサ部２４１とポストプロセッサ部２４２とを有する。メインプロセッサ部２４１は、ＣＡＤ（Computer-Aided Design）２６０から取得した形状データに基づいてＣＬデータ２４３を生成する。ポストプロセッサ部２４２は、ＣＬデータ２４３からＮＣプログラム２３０を生成する。ＮＣプログラム２３０は、ワーク情報や治具情報２７０とともに、情報処理装置２００に送られる。 The CAM 240 has a main processor section 241 and a post-processor section 242 . The main processor unit 241 generates CL data 243 based on shape data acquired from a CAD (Computer-Aided Design) 260 . A post-processor section 242 generates an NC program 230 from the CL data 243 . The NC program 230 is sent to the information processing device 200 together with work information and jig information 270 .
　ＮＣシミュレーション部２０１は、ＣＡＭ２４０において生成されたＮＣプログラム２３０に基づいて加工シミュレーションを行う。 The NC simulation unit 201 performs machining simulation based on the NC program 230 generated by the CAM 240 .
　判定部２０２は、加工シミュレーションにおいて、工具および工具取付部の少なくとも一方が、ワーク、治具および機械カバーの少なくとも一つの周囲の所定領域に入る位置座標を、第１分割点として判定する。言い換えれば、シミュレーション中の位置決め動作でワーク/治具/工具/機械カバーがあらかじめ指定した距離よりも接近する分割点を認識する。 The determination unit 202 determines the position coordinates at which at least one of the tool and the tool mounting portion enters a predetermined area around at least one of the workpiece, the jig, and the machine cover as the first division point in the machining simulation. In other words, the division point where the work/jig/tool/machine cover is closer than the distance specified in advance in the positioning operation during the simulation is recognized.
　ＮＣプログラム更新部２０３は、第１分割点において、工具を一時停止させる、または工具の移動速度を低下させるように更新されたＮＣプログラム２５０を生成する。つまり、分割点に基づいて、ＮＣプログラムをアップデートし、一時停止または速度低下させるためのタグ（Ｍコード）を追加する。更新されたＮＣプログラム２５０は数値制御装置２２０に入力される。 The NC program updating unit 203 generates an updated NC program 250 that temporarily stops the tool or reduces the moving speed of the tool at the first division point. That is, based on the breakpoint, update the NC program and add tags (M-code) to pause or slow down. The updated NC program 250 is input to the numerical controller 220 .
　数値制御装置２２０は、工作機械２１０における加工を数値制御する装置であり、ＮＣプログラム２３０を解釈するＮＣインタプリタ２２１と工作機械２１０に制御指令を出力する指令出力部２２２とを含む。 The numerical controller 220 is a device that numerically controls machining in the machine tool 210 , and includes an NC interpreter 221 that interprets the NC program 230 and a command output unit 222 that outputs control commands to the machine tool 210 .
　工作機械２１０としては、例えば、ワークに付加加工（Additive Manufacturing）を加える機械、ワークに除去加工（Subtractive Manufacturing）を加える機械、レーザなどの光を照射して加工する機械などが挙げられる。具体的には、旋盤、ボール盤、中ぐり盤、フライス盤、歯切り盤、研削盤、多軸加工機、レーザ加工機、積層加工機等のように、ＮＣプログラムに基づいて数値制御され、金属、木材、石材、樹脂等のワークに対して、旋削、切断、穿孔、研削、研磨、圧延、鍛造、折り曲げ、成形、微細加工、積層加工等の各種の加工を施す機械であればよい。さらに、工作機械は計測機能を有するものでもよく、タッチプローブやカメラ等の計測器を用いてワークの寸法等を計測可能に構成されたものでもよい。 Examples of the machine tool 210 include a machine that performs additive manufacturing on a work, a machine that performs subtractive manufacturing on a work, and a machine that processes by irradiating light such as a laser. Specifically, lathes, drilling machines, boring machines, milling machines, gear cutting machines, grinders, multi-axis processing machines, laser processing machines, lamination processing machines, etc. are numerically controlled based on NC programs, Any machine that performs various processing such as turning, cutting, drilling, grinding, polishing, rolling, forging, bending, forming, fine processing, and lamination processing on a work of wood, stone, resin, or the like may be used. Furthermore, the machine tool may have a measurement function, and may be configured to be able to measure the dimensions of the workpiece using a measuring instrument such as a touch probe or a camera.
　工作機械２１０は、例えば３軸加工機であり、機械要素として、主軸モータ２１１および送り軸モータ２１２を含む。主軸モータ２１１は、工具を回転させ、送り軸モータ２１２は、ボールねじ等を介してテーブルをＸ，Ｙ軸方向に直線移動させたり、工具またはテーブルをＺ軸方向に直線移動させたりする。工作機械２１０はもちろん５軸加工機でもよい。 The machine tool 210 is, for example, a three-axis machine, and includes a main shaft motor 211 and a feed shaft motor 212 as machine elements. A spindle motor 211 rotates the tool, and a feed shaft motor 212 linearly moves the table in the X and Y axis directions via a ball screw or the like, or linearly moves the tool or the table in the Z axis direction. The machine tool 210 may of course be a 5-axis machine.
　主軸モータサーボコントローラ２１３は、指令出力部２２２からの制御指令に基づいて主軸モータ２１１を制御する。送り軸モータサーボコントローラ２１４は指令出力部２２２からの制御指令に基づいて送り軸モータ２１２を制御する。 The spindle motor servo controller 213 controls the spindle motor 211 based on the control command from the command output unit 222 . The feed shaft motor servo controller 214 controls the feed shaft motor 212 based on control commands from the command output unit 222 .
　数値制御装置２２０は、更新されたＮＣプログラム２５０を解釈し、プログラム中に埋め込まれたタグ（Ｍコード）を認識して、工作機械２１０に特殊な制御指令を出力する。この制御指令は、各種コントローラ２１３，２１４に送られ、主軸モータ２１１や送り軸モータ２１２が所定の位置で、「一時停止」または「低速回転」する。 The numerical controller 220 interprets the updated NC program 250, recognizes the tag (M code) embedded in the program, and outputs a special control command to the machine tool 210. This control command is sent to various controllers 213 and 214, and the main shaft motor 211 and the feed shaft motor 212 are "temporarily stopped" or "low-speed rotated" at predetermined positions.
　つまり、更新されたＮＣプログラム２５０によれば、工作機械２１０でのＮＣプログラムチェック中、位置決め(G0または一定速度以上のG1/G2/G3)動作で、ワーク、治具、工具、工具取付部、および機械カバーが互いに接近するタイミングでは、自動で「一時停止」または「速度低下」する。これにより、オペレータの見過ごしによる干渉事故の発生を防止することができる。なお、量産加工時はプログラムチェックが不要なため、工作機械２１０において「量産モード」ではなく「試作モード」のみ、上記の「一時停止」または「速度低下」を有効にしてもよい。「試作モード」と「量産モード」とは、工作機械でプログラムチェックを行う場合などに工作機械の操作盤上で、選択できるモードである。本実施形態では、「試作モード」と「量産モード」の２つのモードを例に説明しているが、本発明はこれに限定されるものではなく、工作機械２１０は、他のモードを備えてもよい。 In other words, according to the updated NC program 250, during the NC program check in the machine tool 210, the positioning (G0 or G1/G2/G3 at a constant speed or higher) operation, workpiece, jig, tool, tool mounting portion, and automatically "pause" or "slow down" when the machine covers approach each other. As a result, it is possible to prevent the occurrence of an interference accident due to an operator's oversight. Since no program check is required during mass production machining, the above "pause" or "speed reduction" may be enabled only in the "prototype mode" instead of the "mass production mode" in the machine tool 210. FIG. "Prototype mode" and "mass production mode" are modes that can be selected on the operation panel of the machine tool when performing program checks on the machine tool. In the present embodiment, two modes of "prototype mode" and "mass production mode" are described as examples, but the present invention is not limited to this, and the machine tool 210 is provided with other modes. good too.
　工作機械２１０において、サイクルスタートボタン２１５を押下すると、事前設定されている早送りオーバライドの値で各モータ２１１，２１２が再度動作する。 When the cycle start button 215 is pressed in the machine tool 210, the motors 211 and 212 operate again with the preset rapid-forward override value.
　早送りオーバライドはハードウェアのダイアルのため、ソフトウェアで強制的に再開後の早送りオーバライドを設定した場合に、ハードウェアのダイアル値と実際のオーバライドの値にズレが発生する。その場合、ハードウェアのダイアル値を下げて、「ハードウェアのダイアル値」よりも、「再開後の早送りオーバライドの値」が大きくなったときにソフトウェアでの強制的な早送りオーバライドの値の設定を解除し、ハードウェアのダイアル値での設定を有効にする。
　工作機械２１０は、工具または工具取付部が工作機械の他の部分から所定距離だけ離れた位置において工具の移動を停止させるための第１コードまたは、その位置において工具の移動速度を低下させるための第２コード（例えばＭ９９８）を含む加工プログラムを実行可能である。
　また、工作機械２１０は、工具を取り付け可能な工具取付部と、加工プログラムを実行し、工具取付部を移動させる数値制御装置２２０と、第１または第２コードを実行する第１モードと前記第１または第２コードを実行しない第２モードとを選択する選択部（指令出力部２２２に内包される）と、を備える。
　数値制御装置２２０は、選択部での選択に基づいて、加工プログラムを実行する。ユーザは実加工でモードを選択し、工作機械２１０は、選択されたモードに応じて加工プログラム中の干渉回避コード（Ｍ９９８）を実行させる。
　また、工作機械２１０はシミュレーション部を有してもよく、シミュレーションにおいて、干渉回避モード（所定領域での工具の移動停止や移動速度低下）の選択を行ってもよい。 Since the fast-forward override is a hardware dial, if the software forcibly sets the fast-forward override after restart, a discrepancy occurs between the hardware dial value and the actual override value. In that case, lower the hardware dial value, and set the forced fast-forward override value in software when the "fast-forward override value after restart" becomes larger than the "hardware dial value". Clear and enable setting in hardware dial value.
The machine tool 210 has a first code for stopping the movement of the tool at a position where the tool or tool mount is a predetermined distance from the rest of the machine tool, or a first code for slowing the movement of the tool at that position. A machining program containing a second code (eg M998) is executable.
Further, the machine tool 210 includes a tool attachment portion to which a tool can be attached, a numerical control device 220 that executes a machining program and moves the tool attachment portion, a first mode that executes a first or second code, and a first mode that executes the first or second code. and a selection unit (included in the command output unit 222) that selects the second mode in which the second code is not executed.
Numerical controller 220 executes the machining program based on the selection made by the selection unit. The user selects a mode for actual machining, and the machine tool 210 executes the interference avoidance code (M998) in the machining program according to the selected mode.
Moreover, the machine tool 210 may have a simulation unit, and in the simulation, selection of an interference avoidance mode (stopping the movement of the tool in a predetermined area or reducing the movement speed) may be performed.
　図３は、情報処理装置２００での処理を説明するための図である。加工シミュレーションにおいて、工具３０１および工具取付部３０２が点１から点２～４を経て点５まで軌道３０３上を動くように、ＣＡＭ２４０が生成したオリジナルのＮＣプログラム２５０が構成されているとする。ただし、点１から点２までの移動は位置決め（Ｇ０）指令によるものであり、点２から点３を経て点４までは、切削送り（Ｇ１）指令によるものである。さらに点４から点５までの移動は、位置決め（Ｇ０）指令によるものである。 FIG. 3 is a diagram for explaining the processing in the information processing device 200. FIG. Suppose that the original NC program 250 generated by the CAM 240 is configured such that the tool 301 and the tool mounting portion 302 move on the trajectory 303 from point 1 to point 5 via points 2 to 4 in the machining simulation. However, movement from point 1 to point 2 is based on a positioning (G0) command, and movement from point 2 through point 3 to point 4 is based on a cutting feed (G1) command. Further, movement from point 4 to point 5 is due to a positioning (G0) command.
　判定部２０２は、まず、ワーク３０４の位置（範囲）からＸ方向、Ｙ方向およびＺ方向に指定された距離（ここでは例として５０mm）だけ離れた位置に境界線３０５，３０６を設定し、その境界線の内部を指定距離領域３０７とする。なお、ここでは、各軸に同じオフセット量（距離）を設定したが、本発明はこれに限定されるものではなく、各軸に異なるオフセット量を設定してもよい。また、ワーク、治具、カバーごとに異なるオフセット量を設定してもよい。さらには、ここで指定距離領域３０７は、ワーク、治具、カバーなどからの「距離」によって定められているが、本発明はこれに限定されるものではない。ワーク、治具、カバーなどの位置に基づいて定められ、干渉防止を考慮した形状の所定領域であれば、どのような領域でもよい。 First, the determination unit 202 sets boundary lines 305 and 306 at positions separated from the position (range) of the workpiece 304 by specified distances (here, 50 mm as an example) in the X, Y, and Z directions. A designated distance area 307 is defined as the inside of the boundary line. Although the same offset amount (distance) is set for each axis here, the present invention is not limited to this, and different offset amounts may be set for each axis. Also, different offset amounts may be set for each workpiece, jig, and cover. Furthermore, here, the specified distance area 307 is defined by the "distance" from the work, jig, cover, etc., but the present invention is not limited to this. Any region may be used as long as it is determined based on the positions of the workpiece, jig, cover, etc., and has a shape that takes interference prevention into consideration.
　指定距離領域３０７は、ワーク、治具および機械カバーの少なくとも一つから所定距離以内の領域である。あるいは、指定距離領域３０７は、ワーク、治具および機械カバーの少なくとも一つから、Ｘ方向に第１距離以内かつ、Ｚ方向に第２距離以内の領域である。 A specified distance area 307 is an area within a predetermined distance from at least one of a workpiece, a jig, and a machine cover. Alternatively, the designated distance area 307 is an area within a first distance in the X direction and within a second distance in the Z direction from at least one of the workpiece, jig, and machine cover.
　図３では、指定距離領域３０７を矩形領域として描いているが、本発明はこれに限定されるものではなく、ワーク（材料）の形状に応じた領域となる。また、図３では、指定距離領域３０７は、平面形状のように見えるが、実際には、立体形状である。 Although the specified distance area 307 is drawn as a rectangular area in FIG. 3, the present invention is not limited to this, and is an area corresponding to the shape of the workpiece (material). Also, although the designated distance area 307 looks like a planar shape in FIG. 3, it actually has a three-dimensional shape.
　そして、軌道３０３が、指定距離領域３０７の内部に入る点を分割点１とし、軌道３０３が指定距離領域３０７の内部から出る点を分割点２とする。分割点１、２の座標を用いて、オリジナルのＮＣプログラム２３０を修正し、更新されたＮＣプログラム２５０を生成する。つまりＮＣプログラム更新部２０３は、分割点１において、工具を一時停止させる、または工具の移動速度を低下させるようにＮＣプログラム２５０を生成する。 A point at which the trajectory 303 enters the designated distance area 307 is defined as a division point 1, and a point at which the trajectory 303 exits the designated distance area 307 is defined as a division point 2. The coordinates of division points 1 and 2 are used to modify the original NC program 230 and generate an updated NC program 250 . That is, the NC program update unit 203 generates the NC program 250 so as to temporarily stop the tool or reduce the moving speed of the tool at the dividing point 1 .
　同時に、加工シミュレーションにおいても、分割点１から分割点２までの工具３０１の移動速度が低下するように制御する。なお、ここでは速度を低下させる例について述べるが、本発明はこれに限定されるものではない。加工シミュレーションにおいても、工作機械２１０においても、分割点１で、工具３０１を停止させて、オペレータに手動での移動を促してもよい。 At the same time, also in the machining simulation, control is performed so that the moving speed of the tool 301 from division point 1 to division point 2 is reduced. Note that although an example of reducing the speed will be described here, the present invention is not limited to this. In both the machining simulation and the machine tool 210, the tool 301 may be stopped at division point 1 to prompt the operator to move manually.
　例えば、図４に示すように、点１から点２までの移動の前に、分割点１において、Ｍ９９８という、干渉チェックオンを表すＭコードのコマンド２５１を挿入する。さらに、点４から点５までの移動の前に、分割点２において、Ｍ９９９という、干渉チェックオフを表すＭコードのコマンド２５２を挿入する。Ｍ９９８は、干渉チェックオンを意味し、モータの低速回転開始指令であり、Ｍ９９９は、干渉チェックオフを意味し、モータの低速回転終了指令であると、数値制御装置２２０においてあらかじめ対応テーブルが用意されているものとする。 For example, as shown in FIG. 4, before the movement from point 1 to point 2, at division point 1, M998, an M-code command 251 representing interference check-on, is inserted. Further, before the movement from point 4 to point 5, at division point 2, an M-code command 252, M999, representing interference check off is inserted. M998 means interference check-on, which is a low-speed motor rotation start command, and M999 means interference check-off, which is a low-speed rotation end command for the motor. shall be
　つまり、ＮＣプログラム更新部２０３は、分割点１において、工具の移動速度の低下を開始させ、分割点２において工具の移動速度の低下から復帰させるＮＣ工プログラムを生成する。 In other words, the NC program update unit 203 generates an NC machining program that starts decreasing the moving speed of the tool at the dividing point 1 and recovers from the decreasing moving speed of the tool at the dividing point 2 .
　これにより、工作機械２１０は、更新されたＮＣプログラム２５０を実行すると、埋め込まれたコマンド２５１，２５２を認識して、オペレータが何も操作しなくても、分割点１から分割点２まで、低速で工具３０１が移動する。これにより、オペレータは、工具と、加工対象や、加工対象をホールドする治具（例えば爪）が接近するタイミングでは、それらが本当にぶつからないか、じっくりと寸法チェックすることができる。 As a result, when the updated NC program 250 is executed, the machine tool 210 recognizes the embedded commands 251 and 252, and the machine tool 210 moves from the division point 1 to the division point 2 at low speed without any operation by the operator. , the tool 301 moves. As a result, the operator can carefully check dimensions to see if they really collide at the timing when the tool, the object to be processed, or the jig (for example, a claw) that holds the object to be processed approaches.
　量産加工時は干渉チェックが不要なため、工作機械２１０に「試作モード」と「量産モード」を用意して「試作モード」の時のみ、コマンド２５１，２５２を有効にしてもよい。つまり、「量産モード」では、上述したＭ９９８やＭ９９９を読み飛ばす仕様にすればよい。 Since the interference check is unnecessary during mass production machining, the machine tool 210 may be provided with "prototype mode" and "mass production mode" and the commands 251 and 252 may be enabled only in the "prototype mode". In other words, in the "mass production mode", the above M998 and M999 may be skipped.
　工作機械２１０は、接近する対象物によって、ワークを外して干渉チェックしてもよい。また、ワーク（材料）をつけて、ＮＣプログラムを走らせながら、工具を交換してから加工を開始するまでの、最初の工具のアプローチや、加工が終了してから工具が待機位置に退避するまでの動きを、低速状態でチェックしてもよい。 The machine tool 210 may remove the workpiece and check for interference depending on the approaching object. In addition, while attaching the work (material) and running the NC program, the first tool approach from tool replacement to the start of machining, and the time from the end of machining to the retraction of the tool to the standby position. movement may be checked at low speed.
　シミュレーションでのチェックに合わせて、実際の工作機械２１０でも低速でチェックすることにより、より一層確実に干渉事故を回避することができる。 By checking the actual machine tool 210 at a low speed in conjunction with the check in the simulation, interference accidents can be avoided more reliably.
　図５は、情報処理装置２００での処理の流れを説明するフローチャートである。 FIG. 5 is a flowchart explaining the flow of processing in the information processing device 200. FIG.
　情報処理装置２００は、ステップＳ５０１において、ＣＡＭ２４０から、機械情報、ワーク情報、治具情報および工具情報２７０を取得する。次に、ステップＳ５０２では、ワークおよび治具、機械カバーなど、干渉が懸念される部材の周囲に、指定距離領域を設定する。 The information processing device 200 acquires machine information, work information, jig information and tool information 270 from the CAM 240 in step S501. Next, in step S502, a specified distance area is set around members that may interfere with each other, such as workpieces, jigs, and machine covers.
　さらにステップＳ５０３では、工具等の軌道が指定距離領域に入る第１分割点の座標、および指定距離領域から出る第２分割点の座標を算出する。 Further, in step S503, the coordinates of the first division point where the trajectory of the tool or the like enters the designated distance area and the coordinates of the second division point where it exits the designated distance area are calculated.
　ステップＳ５０４では、加工シミュレーション中、第１分割点から第２分割点までの軌道における工具の移動速度を低速化する。 In step S504, the moving speed of the tool on the trajectory from the first division point to the second division point is reduced during the machining simulation.
　ステップＳ５０５では、ＣＡＭからのオリジナルＮＣプログラムに対して、第１分割点から第２分割点まで、工具等が低速で移動するように所定のコマンドを挿入し、更新されたＮＣプログラムを生成する。 In step S505, a predetermined command is inserted into the original NC program from the CAM so that the tool or the like moves at low speed from the first division point to the second division point, and an updated NC program is generated.
　その後、工作機械２１０では、更新されたＮＣプログラムにしたがって、試作モードの動作を行い、干渉のチェックを行った後、実加工に進む。 After that, the machine tool 210 operates in the prototype mode according to the updated NC program, checks for interference, and then proceeds to actual machining.
　以上、本実施形態によれば、工作機械での干渉チェックにおいて、干渉が起こりそうな領域で自動的に工具が一時停止したり、移動速度が低下したりするため、オペレータは、余計な操作を行うことなく、干渉を確実にチェックでき干渉事故を防止できる。 As described above, according to the present embodiment, in the interference check on the machine tool, the tool automatically stops temporarily in an area where interference is likely to occur, or the moving speed is reduced. Interference can be checked without fail, and interference accidents can be prevented.
