Από τις μέχρι σήμερα πληροφορίες ξέρουμε ότι η BMW θα παρουσιάσει τη νέα Σειρά 5 στην έκθεση του Detroit, τον ερχόμενο Ιανουάριο.
Όμως, σήμερα η γερμανική εταιρία έδωσε ένα δελτίο τύπου, που θέλει να μας δείξει ένα νέο scanner για το έλεγχο ποιότητας, που έχει εγκαταστήσει στο εργοστάσιο της, και φυσικά στις φωτογραφίες υπάρχει ελαφρώς καμουφλαρισμένη η 5άρα (G30). Αυτό ίσως σημαίνει ότι το ντεμπούτο της είναι κοντά, αλλά μπορεί να μη σημαίνει και τίποτα.
Όσο αναφορά το μηχάνημα, η BMW είναι η πρώτη κατασκευάστρια αυτοκινήτων που το χρησιμοποιεί, το οποίο είναι πλήρως αυτοματοποιημένο, και διαθέτει ένα οπτικό κύτταρο μέτρησης στο πιλοτικό εργοστάσιο της στο Μόναχο. Ελεύθερα κινούμενοι ρομποτικοί βραχίονες με αισθητήρες δημιουργούν μια τρισδιάστατη εικόνα του οχήματος, για να δημιουργήσουν ένα 3D μοντέλο από τα δεδομένα που λαμβάνουν, με ακρίβεια μικρότερη από 100 μικρά.
Όπως κατάλαβες, η επόμενη γενιά της BMW Σειράς 5 θα είναι το πρώτο αυτοκίνητο που θα επωφεληθεί από αυτή τη νέα τεχνολογία.

The virtual new BMW 5 Series:
High-precision, fully-automated measuring technology generates 3D data model of upcoming generation
Unique system concept with fully-automated, optical measuring cell used for the first time in the automotive industry
Measurement data creates complete virtual vehicle Next-generation BMW 5 Series Sedan benefits from new process
Munich. The BMW Group is the first automobile manufacturer to introduce a unique system concept with a fully-automated, optical measuring cell in its pilot plant in Munich. Freely moving robot arms use sensors to create a three-dimensional image of the entire vehicle and generate a 3D data model from the data captured, with an accuracy of less than 100 μm. This allows barely visible deviations to be identified at an early stage.
The optical measuring cell is deployed at the interface between development and series production. It forms part of the BMW Group’s digitalisation strategy for production and supports the high quality standards for production of premium vehicles. The next generation of the BMW 5 Series Sedan will be the first to benefit from this new technology.
Eduard Obst, Head of Geometric Analysis, Measuring Technology and Cubing, Total Vehicle, explains: “We are delighted to reach this genuine milestone in preproduction with the optical measuring cell: A single measurement provides us with a 3D data model of the total vehicle. Lengthy individual measurements and data collation are no longer needed – saving time and enhancing quality at the start of series production.”
A robot arm on rails mounted on each longitudinal axis of the optical measuring cell moves freely as it maps the vehicle in complete space. Occupying a relatively small area, this set-up allows two small, flexible robots to be used in parallel in an optimum working range. Compared with previous processes, in which robots use a single sensor to record one side of the vehicle after the other, measurements now only take around half the time and are completed within just a few days.
The robots are fitted with two sensors that record reference points and then capture individual surface areas of approx. 80 x 80 cm each. These are combined to form a scan of the entire vehicle. Analysis of the data quickly reveals any deviations, allowing technical integration specialists in the Production division to take appropriate action early on.
Three-dimensional vehicle scanning can be fully automated and performed at off-peak hours or at night, so the measuring cell can be utilised to full capacity. With results delivered promptly, update cycles are shorter or no longer needed. The measurement data and analysis findings are shared online within the production network and also made available to the plant responsible for series production to assist with their preparations.
The fully-automated optical measuring cell is gaining increasing importance within the BMW Group. This technology has been successfully used in toolmaking in Munich since 2015 for complete measurement of individual sheet-metal parts, as well as tool inspection.
The BMW Group is currently exploring the use of automated optical measurement at its automobile plants.
