Once a production line has been set up, manufacturers need to inspect selected samples to monitor wear, setup deviations, or verify every individual assembly, to inspect critical joints and welds. High-end manufacturing has always required feedback of reliable measurements to adjust parameters precisely, and keep components within tolerance. The better and more regular the data provided, the more tightly a production line can be controlled.
Nikon’s Laser Radar technology - capable of providing fast, automated and accurate absolute measurements - clears the way for faster feedback of quality information. This leads to exceptional levels of accuracy, high manufacturing efficiency, reduced rework and less scrap.
A twin robot-mounted Laser Radar system in the production line performs full, accurate, absolute measurements in minutes. There is minimum disruption to the sequencing of production and no the need for manual movement to a CMM room. The same system can be used off-line, as an alternative to a CMM, allowing complete BIW (body-in-white) measurements in less than two hours, compared to up to eight hours for a conventional touch-probe CMM.
Taking measurements in absolute coordinates using Laser Radar technology, together with enhanced data collection and reporting, are ideal for integration into a digital manufacturing environment. It allows the advantages of Quality 4.0 to be leveraged, with 'big data' used to control the process better, and to compare information over time. This facilitates enhanced insight, improved decision making, and faster product development.

Faster ramp-up of pre-series
With low production rates during pre-series, Laser Radar enables in-line inspection of all the points on a car, to the same standard as a CMM, generating far more data than before. This allows much faster ramp-up to higher quality products saving time and ultimately money.
Off-line measurement room vs in-line or at-line Laser Radar solution
Using the Laser Radar technology, the off-line measurement facility ceases to be a bottleneck due to faster acquisition of more features. Parts do not need to be moved to the CMM room for systematic measurement - only troubleshooting - relieving sequencing issues and greatly improving measurement productivity. Having the same program running off-line and in-line ensures consistency of results. Set-up is quicker, as is programming, which increases throughput and reduces bottlenecks.

Laser Radar for inline inspection video
With the need for shorter and more flexible production cycles, automotive manufacturers are continuously looking to cut time and costs whilst improving product quality. The Laser Radar mounted on an industrial robot introduces an innovative approach to body-in-white (BIW) inspection.
Laser Radar for bypass inspection video
Line-side inspection with rotating table: a car body is taken from the line onto a rotating table. A Laser Radar on a fixed lift inspects the body from different sides.
Laser Radar has a spherical field-of-view, meaning it has visibility to large sections of the vehicle at any time and dozens of features on the vehicle can be measured from a single location. Just like a CMM, measurements are pre-programmed directly from the vehicle’s CAD model using the inspection software.
Laser Radar for streamlining component inspection video
Single Laser Radar services multiple inspection stations. Part rotation allows for inspection of features on both sides. Data can be used for process control or incoming component validation.
