Below we have listed some areas where dimensional Metrology is widely applied:
1) A flexible, low cost robotic platform for the aerospace sector
A major Airbus research project to develop greater levels of accuracy in automated drilling and riveting has led to the formation of a consortium to build a robotic platform incorporating a Nikon Metrology K-series Optical CMM.
Since industrial robots do not meet Airbus process specifications; Airbus, Nikon Metrology, KUKA and Delmia have formed a consortium to build a new aerospace grade robotic platform.
Initially the system will be applied to two KUKA production robots that jointly pick up an unfinished large wing assembly, and present this part to a drilling/riveting station at a fixed location. Both the drilling/riveting machine and the part being manufactured (through its fixture) are tracked dynamically by means of infrared LEDs and the Nikon Metrology K-series Optical CMM station. As part of the control feedback loop, the position of the part with respect to the machine is systematically returned to the robot controller. This Nikon Metrology/KUKA robotic solution is responsible for positioning wing part holes and rivets at CAD-specified wing locations with accuracy levels 10 times higher than before.
2) Laser Scanner speeds up body geometry verification at Volvo Cars Gent
The innovative Nikon Metrology Cross Scanner is used at Volvo Cars Gent to further accelerate the design-through-manufacturing process for its brand new Volvo XC60 crossover vehicle. By digitizing physical sheet metal and plastic body parts and virtually assembling vehicle bodies in software, Volvo engineers completed pre-production geometry verification nearly twice as fast! 3D laser scanning technology, point cloud processing and virtual assembly shortened physical evaluation of prototypes and eliminates the need for costly specialized verification tooling.
