Industrie : Aérospatiale

JR Machine attire les clients de l’aérospatiale grâce à des techniques avancées de fraisage en fraisage-tournage

JR Machine increased its shop capabilities without updating any of its existing machines or installing new ones simply by upgrading its CAD/CAM software. In doing so, JR Machine reduced programming time and increased part quality.

Présentation

Défi

Programmation et découpage de pièces aérospatiales nécessitant à la fois du fraisage et du tournage.

Solutions

Mastercam, le logiciel de CAO/FAO le plus robuste pour les applications d’usinage.

Résultats

Advanced CAD tools make complete, accurate models of parts from vector-based drawings. Mill-Turn combines the best functions of both applications, reducing programming and machining time. Simulation, Backplot, and Verify visualize the machining process and identify possible problems. Dynamic Turning automates tool motions to run machines faster and more safely. 3 + 2 machining approaches allow users to apply some multiaxis techniques without having to upgrade software or equipment.

Détails du projet

JR Machine is a leading contract manufacturing company for complex precision machined parts. “We’ve really tried to target the aerospace industry, which requires highly complex parts,” said Shane Kunschke, JR Machine vice president of manufacturing. “That’s what drove us to purchase our Mastercam CAD/CAM software. We haven’t made any CNC machine upgrades, but our machines are now capable of doing this type of high-end work.”

The CAD portion of the software renders the customer’s vector-based drawing to create an accurate and precise model of the part, complete with tolerances and surface finishes. Because JR Machine uses an integrated system, pulling the CAD file into its CAM interface takes no time and means no loss of data. Now, the company is able to work with whatever prints and models it receives.

In the case of complex aerospace parts, JR Machine was writing a workable CAM code but having to return to it often to hand-edit the G-code. Lead Programmer Brock Jaskolski shared that he found writing a mill program easiest, but had to tweak it to work with his lathes, essentially doubling his programming time and increasing operator error. Jaskolski knew his software could do better. He reached out to his certified local Mastercam Representative, ShopWare Inc. in Elgin, IL.

L'utilisation de Mastercam a vraiment facilité la formation. Aujourd'hui, il est beaucoup plus facile d'amener les gens à la vitesse de croisière. Il est difficile de trouver des employés expérimentés, alors si Brock peut programmer une pièce au bureau et la rendre presque infaillible lorsqu'elle est envoyée à la machine, il est plus facile pour un opérateur de comprendre ce qui se passe. L'opérateur n'a plus besoin de masser le programme ou de savoir exactement ce que fait chaque ligne de code.

ShopWare Application Expert Todd Rathkamp was quick to suggest the software’s Mill-Turn solution, which harnesses the powers of milling’s tool rotation and turning’s workpiece rotation. Parts that previously would have been turned on a lathe and then milled can now be cut entirely on one CNC machining center with Mill-Turn. Productivity is greatly increased because multitasking CNC machines reduces multiple setups, manual part handling, redundant fixturing, and machine downtime.

Jaskolski relies heavily on the Mill-Turn product’s included simulation package. In addition to verification functions, the integrated simulation offers a digital twin of whichever machining unit is paired with a particular part. Jaskolski can load his program and watch it run in real-time on a detailed virtual representation of his CNC units.

Le représentant de Mastercam a également suggéré le tournage dynamique, basé sur la technologie Dynamic Motion. Les parcours dynamiques tiennent compte du stock et sont intelligents. Pendant l’usinage, un parcours de tournage dynamique ajustera la vitesse de rotation, l’angle de coupe et la profondeur de l’outil pour s’adapter parfaitement à l’environnement d’usinage. La taille des copeaux est optimisée, les matériaux et les outils sont protégés et la machine peut fonctionner plus rapidement que jamais.

The parts the company takes on are becoming more and more complex. To meet this head-on, Jaskolski uses CAD/CAM software to simulate 3 +2 simultaneous machining. This style of machining harnesses the power of multiaxis machining within a 3-axis environment by tilting the tool held at a fixed angle. Using a successive sequence of orientations, users can mimic 5-axis simultaneous machining without going all-in on multiaxis.
