Automotive focus at CONTROL


Faced by ever-shortening development and production cycles, vehicle manufacturers and their suppliers are falling back on solutions from Hexagon Metrology to accelerate the launch of new products, increase productivity, reduce waste and optimise the quality of their products. For this year's appearance at CONTROL 2011, the now ten-year-old metrology company places the focus on the dynamic industry: on Booth 5302 in Hall 5 everything revolves around the car. Consequently the trade fair booth concept follows the production process in automobile manufacture – starting with advanced development and design before moving on to tool- and mouldmaking, component manufacture and assembly.

A Cognitens WLS400A measuring cell on the booth demonstrates white-light technology, which is a powerful tool for the fully automatic inspection of bodywork components. Physical models found in prototype manufacture for instance are scanned and digitalised with the ROMER Absolute Arm portable measuring machine. Measuring arms are also employed for the inspection of parts during manufacture or for the fit-and-finish inspection when features in the vehicle interior have to be measured. If the task is to carry out several body-in-white inspections, measure large components and fixtures or set up machines all at once, then laser tracker systems and laser stations from Leica Geosystems are suitable solutions. The compact Leica Absolute Tracker AT401 is the industry's first battery-powered laser tracker and was developed for 3D measurements over long distances. The Leica Absolute Tracker AT901 is the key piece of kit in a portable high-performance measuring system. In conjunction with manually or robot-guided optical or tactile sensors, or with the Leica T-Probe or the Leica T-Scan, the Leica Absolute Tracker AT901 proves to be an all-round star performer on the metrology stage.

Stationary coordinate measuring machines are primarily responsible for the quality control of drive chains. Coordinate measuring machines sporting the DEA and Leitz labels are used in vehicle manufacturing for checking powertrain components, such as gearbox and crankcases, engine blocks, cylinder heads or crank- and camshafts. For smaller components, for example electronic components including circuit boards or airbag, ABS, EPS and rain sensors, Hexagon Metrology can provide Optiv multisensor measuring systems, which combine optical and tactile measurements in a single system. Products from TESA – hand-held measuring instruments, height meters, surface roughness testers etc. – are perfect for all kinds of parts in metal or plastic. The PC-DMIS and QUINDOS software packages as well as a comprehensive range of services round off the Hexagon Metrology portfolio.

In addition to automobile manufacture, Hexagon Metrology is active in many other industries: customers come from the fields of aerospace, machine making, the energy sector, shipbuilding and railway construction, heavy industry, biomedical engineering etc. The objective for Hexagon Metrology remains the same in each case – to identify the most suitable system for the application.
