Nikon Metrology’s Accurate Precision Distance Scanning (APDIS) system offers precise, no touch measurement capabilities designed to boost quality and efficiency on automotive and other large-scale production lines.

Nikon Metrology’s Laser Radar has been at the forefront of a quiet revolution in automotive quality control, bringing high accuracy, absolute measurements to the shop floor. With over 150 installations in 36 vehicle plants worldwide, the Laser Radar has proved itself to be an invaluable tool for manufacturers to improve their quality, reduce scrap and ultimately save money.

The release of the new APDIS Laser Radar builds on this success to give the most productive Laser Radar ever built. This will drive the changes required for an automotive industry that has for many years been striving to achieve better productivity and higher overall quality.

APDIS is capable of measuring almost any surface, providing faster measurements at just 2-3 seconds per feature to identify quality issues early on. A built-in orientation sensor allows for measurements in any orientation when robot mounted, with auto detection to load calibration data automatically. Additionally, an industry first direct surface vibration measurement capability allows installations and machines to be analyzed safely and remotely with the inbuilt laser technology.

Precise control over the scan path and accurate, point cloud-based feature measurements keep data sets small. Holes, slots and other sheet metal features can each be measured in a few seconds and specific surface points at several per second. Combined with fast movements between features, it enables short measurement times to be achieved. Even traditionally troublesome features such as studs can be scanned and measured rapidly without the need for adapters.

To ensure quality visuals, a new, high-definition Nikon camera coupled with new Nikon confocal optics offers better viewing of what is being inspected, helping to deliver the right data in real-time.

APDIS is 40% lighter and 25% smaller than its previous generation of Laser Radar. The smaller size and a shorter range – from 0.5m (1.6-feet) – allows it to fit into tight factory spaces as well as for ease of movement around the production floor.

Another improvement over traditional technologies and previous Laser Radar systems is a rapid warmup time, cutting the warm up time to 15 minutes from power on.

By closely monitoring production quality during the early build phase, the manufacturing process can be instantly adjusted when variances occur over time, reducing the risk for flaws and costly fixes. The touchless technology offered by APDIS allows for less risk of harming parts or the Laser Radar itself, removing unnecessary line stoppages due to part collisions.

Further, the APDIS scanner is sealed to protect the laser system from the dust and water often found in manufacturing facilities and meets the rigorous industry standards of IP54 (IEC 60529).
