General
A head light, a suspension part, a wheel rim, a bumper or a plastic air filter box; each automotive component has to meet predefined dimensional specifications. Falling short on these specifications is simply not an option for automotive suppliers.
Quick inspection checks on the shop floor or near the production machine can be executed with a manual inspection system. Metris MMD laser scanners outperform touch probe inspection systems in terms of productivity and level of detail. The laser scanner operates in combination with an articulate arm (Metris, Faro, Cimcore) or an optical CMM (Metris K-scan).

For more accurate and systematic inspection, Metris LK and C3 coordinate measuring machines (CMMs) cover a wide range of metrology system configurations to meet any combination of measurement accuracy, volume and speed. The Metris Camio software supports touch trigger, analog scanning and laser scanning measurements in a very transparent way.
Automated in-line inspection
In production facilities for automotive parts, manual geometric inspection tasks may slow down manufacturing throughput. Repetitive measurement actions performed in serial production environments additionally need to comply with tight requirements in terms of measurement repeatability.
A K-Robot system equipped with a laser scanner addresses this issue by offering fast and consistent in-production-line inspection. Metrology-level scanning accuracy in combination with real-time scanner position tracking provides a detailed 3D representation of the scanned object. In-line robotic scanning is ideally suited for systematic production quality monitoring.
Interior trim
In recent years, interior design has become equally important as the exterior looks of a car, driving the need for carefully shaped trim components. Where possible, soft materials are used to achieve a better tactile experience. These trends create specific challenges for dimensional quality control. Traditional manual gauges and touch trigger based coordinate measurements do not provide enough information to evaluate complex shapes. In addition, the repeatability of tough trigger measurements on soft surfaces is rather poor.
Laser scanning is the right answer for both challenges: as it is a contactless measurement technique its can measure soft materials in a very repeatable way. At the same time, laser scanning provides more than sufficient measurements points to thoroughly evaluate components’ contours and features.
Metris LC/XC scanners are compatible with Metris’ complete range of LK and C3 CMMs. Focus Scan supports LC/XC scanners that are deployed on third party CMMs. Through Focus Automation, the entire measurement and inspection process – using Focus Inspection - can be automated.
