Mesure et diagnostic automatisé des machines-outils à cinq axes

Lorsque les pièces usinées présentent des non-conformité il faut rapidement trouver la source du problème et la corriger. Mieux encore il faut prévenir le problème et par des mesures régulières pour détecter des tendances. Mais ceci n’est possible qu’avec de l’information quantitative périodique sur l’état de santé géométrique de la machine. Ces opérations métrologiques exigent des temps non-productifs qu’il faut garder au stricte minimum. C’est là où les méthodes basées sur le palpage automatisé d’artefacts indigènes ou non-calibrés montre tous leurs avantages. La norme ISO-230 définit les erreurs géométriques des machines-outils à cinq axes. Elles sont au nombres de huit erreurs d’alignement entre les axes de la machine et 30 erreurs dans la qualité du mouvement de chaque axe. Les machines cinq axes ont ceci de particulier qu’elles peuvent positionner leur outil au même endroit avec différentes orientations des axes rotatifs. Cette redondance permet de les mesurer par palpage d’artefacts très simples, voir même sans artefacts ajoutés.

Les mesures sont automatiques et ne nécessitent aucune intervention humaine. Les données permettent de quantifier la précision globale de la machine et de déterminer les causes d’une précision déficiente. Cela permet ensuite de cibler et de planifier les opérations correctives.

La présentation débutera par des explications des erreurs volumétriques et paramétriques des machines-outils, suivi de la méthode pour les mesurer. Des exemples de mesures sur trois machines dont une horizontale, une vertical et une portique seront présentés.

The recent trend towards the adoption of collaborative robots is opening up a number of exciting potential uses and benefits. However, the same technological advances are also making it possible for manufacturers to perform many of these same collaborative applications with industrial robots. Finding the solution that provides optimal results depends on matching the right stage of Human-Robot Collaboration with the application. But how do you know which stage is right for you?

This presentation will identify and share examples from each of the six stages of Human-Robot Collaboration (HRC), giving attendees with working definitions for a successful utilization of robots in each stage. The speaker will draw on real-world applications to provide the audience with actionable advice for optimal utilization, as well as discuss the pros and cons of using either a collaborative or industrial robot in each scenario.

Need: Flexible automation is a crucial factor in the survival of enterprises.

This presentation addresses the emerging field of collaborative robots, robots working as robots should… robots collaborating with humans to improve performance and productivity.

The perfect part. The Holy Grail of manufacturing today is to produce parts with absolutely no quality defects, zero scrap rate, and no time required for change over to new product builds when required.

This basic driving force behind manufacturing has now transformed into the Industry 4.0 concept of the ultimate flexible manufacturing line. It is clear that embedded or in-line quality and measurement systems will play an integral part of future manufacturing systems.

What do some of these concepts look like today and where are we going in the not so distant future with the automation of in-line metrology?

Faced with the growing demand for more personalized and varied products in a competitive global marketplace, today’s manufacturers are looking for faster, more creative ways to overcome space limitations and other complex production challenges. Many have turned to collaborative and mobile robotics systems to meet their needs. Combining the strengths of a collaborative robot with a mobile platform, these vehicles use intelligent software and sensors to navigate crowded factory floors and perform a number of tasks. But how does a manufacturer know if a mobile robot is right for their application?

Using real-world case studies, this presentation will show how mobile robots are being used to increase the flexibility of automation projects in different work settings.

From generative design to additive manufacture, the way we create products has drastically changed in the past decade or two. But more than ever, the key success factor in this new paradigm is not so much the technology but rather the way we work together, across disciplines. Altair’s Simulation Driven Design philosophy has evolved from 25 years of experience helping our customers design and implement innovative designs. It helps facilitate the communication between the specialties and provide a platform to better understand those different aspects from the first initial concept while help reduce the risks at later stages of the project.

The presentation will give an overview of the Simulation Driven Design philosophy, focusing mostly on the interaction between design, analysis and manufacturing disciplines. It will highlight the key benefits for each of them.
