ベリカット オプション機能:マシンプロービング(機上計測)

NCマシンプロービングのモジュールにより、NCプローブプログラムを作成できるようになりました。  
ベリカットには、他のどのNC加工工程にもないインプロセスモデルがあるため、プローブのルーチンを作るには理想的です。NCプローブプログラムを生成するために、ベリカットでシミュレーションしたインプロセス形状モデルを使えば、マシン上でのインプロセス検査が現実のものになります。更に、NCマシニングセンター上でプロービングのシミュレーションを行うことで、プログラムが現場に出回る前に、プローブを壊す可能性のあるエラーを検知することができます。
 
CNC をプロービング操作に使うと、このモジュールにより事前に、下記のような作業をしてもプローブが壊れたり機械がクラッシュしないことがわかります :
  • 材料や治具の位置決めとオフセットの調整
  • バリエーションのある材料の測定と調整
  • 材料と治具の構成、もしくは機械上の部品番号を識別
  • 工具または治具のオフセットの測定と調整
  • 工具の破損検知
  • 重要な加工部品の検査
どうしてプロービング操作をシミュレーションするのか?
CNC機を使ってプロービング操作をする時には、多くのエラーが発生する可能性があります。プローブの先端とステムはプローブモードにない時でも、他のものに接触して壊れることがあり、その本体と他の機械部品も移動中に何かにあたって、高価な検査用プローブを壊してしまうことがあります。またプローブサイクルロジック中にエラーがあると、予期せぬ機械の動きを引き起こし、機械をクラッシュさせたり、プローブ本体を壊したり、プローブ先端を破損させることになります。
そこで事前にベリカットでシミュレーションを行うと、プロービング操作が頭痛の種になることはありません!プローブモードにない時でもプローブ先端がものに接触し干渉を検知すると、知らせてくれます。またプローブサイクルロジック(これはプロービング中に集めた情報に基づいて、機械動作を変えます)がエラーを引き起こさないことも検証してくれます。

プローブ工具の機能…

プローブ工具を作るのは簡単です。球状の「先端」の直径とシャンクの直径と長さを指定するだけでいいのです。ホルダーを加えると組立てが完成し、検査プローブ全体を保護してくれます。ベリカットはプローブ先端以外のものでも、他のものに触れると干渉を検知します。 
 
ベリカットは特定のパスに沿って、シミュレーションされたプローブを動かします。プローブはその先端がものに接触した時と、プログラムの最後に達した時に、その動きを止めます。機械軸位置などの動作結果は、CNC機で行われるように、ベリカットの標準コントローラのエミュレーションをもつプローブのサブプログラム中に適用されます。
ベリカットは、オフセットの設定に使われる複雑なロジックとタイプⅡフォーマットを含む、プローブサイクルのサブプログラム/プログラムのすべてをシミュレーションし、プロービングの結果に基づいて決定を下します。ベリカットがあなたのカスタムプローブサイクルをどのようにシミュレーションするかを知りたい場合は、CGTech にご連絡ください。
Airbus is selling so well that the demand to increase build rate has never been higher. BAE Systems (Filton, UK) needed a simple way to improve throughput - it found the answer in VERICUT.
With VERICUT, engineers at Stellex Monitor modeled the Sidewinder and Spar Mill machines.
Tell Tool of Westfield, Mass., has integrated VERICUT CNC simulation software into its numerical control program prove-out process.
VERICUT enabled us to start ordinary production after a minimum of time. Since this product is new for Volvo Aero Norge and our company had never before had parts with similar machining complexity, it is difficult to estimate the amount of cost saving.
Before implementing VERICUT, the company experienced the usual time-consuming and expensive manufacturing problems related to NC program prove-outs such as scrap loss, broken tooling, and a danger of occasional machine crash.
Over the last two years, AH has used Machine Simulation to speed the implementation of several new 5-axis machine tools.
VERICUT showed the NC programmers leftover or heavy stock." And the software detected a couple of places where the depth of cut was too large and tools were shanking out," said Collings. They then went back and corrected the errors in the tool path before
Dassault, Seclin initially purchased VERICUT in order to reduce the number of manual prove-outs using polystyrene material, which represented a significant expense in terms of time and money.
VERICUT enabled the designers and programmers see exactly what they were building as and in-process model in different stages of the machining cycle.
We utilized VERICUT to verify the CNC programs for cutting the tooling before they were sent to the machine control,
To protect their investment, they have been using VERICUT since 1996. They have two people to verify the accuracy of their G-code files.
"When we first started using OptiPath we concentrated on the feed rate option; now we use the constant chip thickness capability. With jobs up to 200 hours long, 50% saving is significant like having another machine tool."
The entire process took less than two hours and no manpower was required, whereas, creating the same pattern manually (the old way), would have taken one of our designers several days.
The verification process stays ahead of the actual machine position in the NC code being verified. Opera-tors can see errors before they occur.
The bottom line? Using VERICUT has made Supreme's existing machine tools more productive. Enthusiasm is up, delivery times have been reduced, and pricing is more competitive.delivery times have been reduced, and pricing is more competitive.
Using VERICUT to compare the electrode burn with the mold cavity ensures that we have all the correct clearances in the electrodes and that we have 100% clean-up." says Allen.
If I was using VERICUT at the time I would've caught the problem, and had a chance to fix it before it damaged the part.
Now I rarely see the potential crashes because the students find and correct them before I review the work. Catching those costly problems is a non-event now!
VERICUT can change speeds and feeds according to cutting conditions including difference in material and tooling. It is done automatically; the programmer does not have to make even one manual insert into the code."
Flying shrapnel from shattered cutting tools and components is avoided by using VERICUT to test student programs before they are run on NC machines.
The NC programmers at Ingersoll also rely on the simulation software to prevent mistakes when programming complex, five-axis parts.
After creating the NC programs in Mastercam, they began simulating the machining process in VERICUT by simulating the G-code data. There often can be a difference between the motion as programmed and the code after it's run through the post processor
After selecting VERICUT for third-party verification, each NC programmer attended two days of basic training where they experienced first-hand the type of results they could expect to achieve.
The program simulates milling, drilling, turning, wire EDM, and mill/turn machining operations using both G-codes and CAM output.
VERICUT provides simulation capabilities for the all the 3-5 axis and wire EDM parts, with focused control over the orientation of our 5-axis machine tool including the cutters used on that machine.
The inspection probe is created as a tool in VERICUT so the complete in- cycle gauging sequence is checked for collisions.
The bottom was machined first. This effort took about 24 hours from start to finish. By using VERICUT software from CGTech, Elliot was able to test the NC program for any problems before it was ever cut on the machine.

With data exported from NX, Vericut simulates the cutting process on the shop floor utilizing the machine G-code to detect any issues prior to NC Program release.
