In 2006, BMW delivered a presentation at the GOM International Users Conference enlightening the audience on their vision into automated robotic metrology for inspection of sheet metal parts.
The press shop at BMW‘s Dingolfing plant relies on optical metrology systems including automation and standardization for inspection of shee t metal components. Here, 3D coordinate measuring technology from GOM sets completely new standards, offering high time-saving potential since sensor, automation and inspection software all come from a single-source provider. The automation processes in particular, have been subjected to continuous development in close collaboration with BMW.
This presentation by BMW describes their die panel inspection process as well as a comparison to CMM versus ATOS structured light 3D scanning. Every panel measured in GOM generated a colour map and also a CMM Series point report including Form, Trim and pierce. The review of problems found highlighted that 97% of problems ware form related. After Discussion with the Press shop they confirmed the that generally only the form process would vary due to material spec and press pressure changes and that change in form could be linked the trim and pierce changes due to the change in form location on the die.
Mobile optical 3D coordinate measuring technology is used for quality assurance on the production line in the BMW Regensburg plant. For the assembly of roof modules for convertibles, optical measuring equipment is used in process planning for the machine capability study (MCS) even before the start of serial production. On the assembly line the photogrammetric system then enables flexible inspection to be carried out during manufacture. Thus trends and deviations in production can be detected at an early stage. As result of using optical metrology rework time is reduced and production costs are cut down significantly. Also Quality Management can be specifically improved by means of process capability studies.
The ATOS 3D digitizer, for full-field measurements of surfaces, is utilized world-wide in the injection-molding and plastic-processing industry for form and dimension inspection of injection-molded parts. Due to the 3D full-field color deviation plot, the evaluation of parts is considerably faster and much more efficient compared to conventional measuring methods. In particular, warpage and shrinkage of injection-molded parts are fast and clearly displayed speeding up mold try-out and production control. Thus, the ATOS technology allows companies to keep pace with shorter product cycles and faster lead times.
With a CMM comparison to ATOS, Brembo explains the benefits of using the ATOS 3D scanner in their engineering processes for quality control inspection, first article inspection, 3d machining, production, prototype tests, assembly checks, incoming inspection and failure tests.
Already before the first article inspection (FAI) of the casting, 3-D shape and dimensional analyses provide reliable information for quality control and targeted process optimization. Foundries and forging shops the world over use the ATOS 3-D digitizer from GOM mbH, Braunschweig/Germany, for surface measurements in shape and dimensional control of patterns, sand cores and castings. GOM also offers inspection software, training and support – all from a single source. Longstanding users above all appreciate GOM´s integrated solutions of non-contact and tactile measuring within one system.

It was in France in the mid-1960s that the great American supercar came to life. A low-slung, muscular racing car built to win on the legendary Le Mans race circuit, the Ford GT40 project was spearheaded by Chairman and CEO Henry Ford II. His goal was to change performance car history - and he did. The Ford GT40 car beat the world's best in endurance racing, placing first, second and third at the 24 Hours of Le Mans in 1966 and winning the next three consecutive years.
In automotive production, the individual parts are held in fixtures during mounting and are combined such that precise components and assemblies result. When using large body sheet metals that are not stable themselves, it is particularly important that the fixture forces the sheet metal into the correct shape. Thus, solid welding and rebated joints can be produced and the shape of the assemblies complies with the specifications. In production, Ford uses 60 welding fixtures in the production chain for the right and also for the left side panel. These so-called jigs can be adjusted for holding and clamping the side panel of the 3 and 5 door Ford Fiesta and the Ford Fusion.
Ford Stamping engineering has identified 14 key areas where white light scanning is an enabler to improve timing and quality –process improvements. Systematically going through list and addressing each area in order of importance and what makes business sense –various rates of success. By far the most effective and most successful application to-date is to reduce die rework. Panel inspection using automated cells also expected to be highly successful.
The automotive supplier GEDIA is taking a new approach to quality control. The company is replacing measuring technology based on tactile systems and gauges with full-surface optical 3D coordinate measurement. The implementation of optical metrology systems is making GEDIA more flexible. It i s cutting costs and reducing measurement times.
Dimensional analysis of the prototype molds was conducted with the aid of an ATOS Triple Scan optical 3-D digitizing scanner equipped for blue light scanning (blue light permits accurate measurements regardless of ambient light conditions), supplied by Capture 3D (Costa Mesa, Calif.) and developed by GOM mbH (Braunschweig, Germany). Scanner feedback guided development of the multicavity production molds, optimizing dimensional results while eliminating tuning loops.
Quality assurance and management are growing in importance in industrial development and production. The decentralized production of components by suppliers mean that tight specifications have to be meet to ensure problem-free assembly in final production, resulting in a high-quality final product. As such, optical digitizing systems have become firmly established for inspection of individual sheets, in assembly analysis, and during forming tool try out.
Fuel tanks for cars are typically manufactured using plastic blow molding. To verify the production parameters and optimize the production, the digitizer ATOS II was used. 10 samples were taken out of two production lines with 20 minutes digitizing time for each part. The parameters which were monitored and validated were the production line, the cooling water (temperature and flow), the object temperature before digitizing and the influence of a special process step.
Lamborghini explains why they chose ATOS for 3D scanning applications such as reverse engineering and inspection of their luxury super sports car, and gives a comparison to their previous process using Faro.
