VERICUT Modul: CNC Maschinen Probing zum Messen mit der Werkzeugmaschine
VERICUT wurde um das Modul für CNC-Tastungen erweitert, um Messprogramme erstellen zu können.
VERICUT erzeugt während der Simulation ein im CNC Simulationsprozess einzigartiges Geometriemodell, dass sich ideal zum erstellen von Messroutinen eignet. So wird die Prozessinterne Inspektion des Werkstückes zur Realität. Mit der Simulation des Messvorganges können Fehler gefunden werden, die den Taster beschädigen würden…noch bevor das Programm tatsächlich zum Einsatz kommt!
Bei den folgenden Operationen verhindert der Einsatz dieses Moduls Kollisionen von Taster und Maschine:
Rohteil und Spannmittel lokalisieren sowie Offsets einstellen
Rohteil abtasten und Abweichungen berücksichtigen
Rohteil- und/oder Spannmittelkonfiguration bzw. Teilenummer an der Maschine ermitteln
Werkzeug- und Spannmitteloffsets ermitteln und einstellen
Werkzeugprobleme erkennen
Hauptmerkmale des Fertigteils inspizieren
WARUM MESSOPERATIONEN SIMULIEREN?
Bei Messungen mit CNC-Maschinen können verschiedene Fehler auftreten. Die Tasterspitze bzw. der Tasterschaft berührt womöglich ein anderes Objekt und wird zerstört, während die Maschine nicht im Tastmodus arbeitet. Bei Bewegungen der Maschine kann der Körper des Messtasters oder eine Maschinenkomponente ein anderes Objekt berühren und so der teure Tastfühler zerstört werden. Natürlich kann auch ein Fehler in der Logik des Tastzyklus zu einer unerwarteten Bewegung der Maschine führen und diese beschädigen, den Tastfühler unbrauchbar machen, oder dessen Spitze abbrechen! Mit VERICUT-Simulation bereiten Tastungen keine Kopfschmerzen mehr! Sie werden benachrichtigt, wenn die Tasterspitze ein Objekt berührt, während sich die Maschine nicht im Tastmodus befindet – alle Kollisionen werden erkannt. Auch die Logik des Tastzyklus wird überprüft (die Maschinenbewegung also auf Basis der gemessen Daten korrigiert.
FUNKTIONSWEISE
VERICUT bewegt den simulierten Taster dann entlang des angegebenen Verfahrwegs. Die Bewegung kommt zum Stillstand, sobald die Messspitze ein Objekt berührt oder das Ende des programmierten Verfahrwegs erreicht. Die Ergebnisse dieses Probedurchlaufs (z. B. die Positionen der Maschinenachsen) werden mit der normalen Steuerungsimulation von VERICUT in das Tast-Unterprogramm eingefügt – wie bei Ihrer CNC-Maschine auch. VERICUT simuliert alle Aspekte der Subroutinen/Unterprogramme für Messungen – auch komplexe Logik und Typ II-Formate. So lassen sich Offsets definieren und vom Messergebnis abhängige Entscheidungen treffen.

With VERICUT, engineers at Stellex Monitor modeled the Sidewinder and Spar Mill machines.
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.
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.
Cosworth Racing Integrates Walter TDM Tool Management into Manufacturing Systems
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.
