Industry & Technology
Fast - accurate - reliable: To adhere to this demanding production maxim, regardless of the
task's complexity, requires a sophisticated quality management structure. Reverse engineering, 100% quality inspection and rapid prototyping are firmly established as standard tools which are continuously improved … and along with them are the Breuckmann scanners.
PrintRobot Supported Scanning with a White Light Scanner
The project was carried out at MQS Ingolstadt for the German car manufacturer Audi AG and describes a new approach for the precise automated digitisation of large assembly parts in the automotive industry.
Objective
Objective of the project was the digital documentation and archiving of doors, bonnets and tailgates in order to establish a digital archive of the prototypes developed in the pre-production chain. The digitised prototypes and their respective quality reports are then easily accessed as reference objects in the subsequent optimisation and production phase.
Measuring System and Setup
The project was carried out with the help of a Breuckmann highend 3D naviSCAN 3D system mounted on a Kuka industrial robot. Using special fixing elements, the measuring object was held in position on a large turn table.
Characterised by the combination of a Breuckmann 5.0 MPix stereoSCAN 3D with a Metronor
DUO coordinate measuring machine, the naviSCAN 3D allows for the fast and precise digitisation of large surface objects without the requirement to use reference points.
Result
Thanks to the fast and precise 3D data generation of the naviSCAN 3D, allowing to capture the data without the use of reference points, the complete digitisation of the doors, bonnets and tailgates was accomplished within a few minutes. At an average of approx.
15 minutes, the time allowance for scanning process and change of the scan object given by the customer could therefore be easily met.
