Aicon Optical tracking technology for large measuring volumes
3D Arena from Aicon turns conventional processing stations into flexible areas with mobile machines for various design processes.
New products have to be developed within shorter periods and manufactured at lower costs. Especially in the automotive industry, product cycles from prototype to series-production model have shortened considerably. The interval between two models has almost halved. One reason is the increased consumer demands for design and equipment. To keep a constantly high quality-product, optical 3D metrology has become a standard in all development processes.
3D Arena from Aicon is said to allow optical positioning and alignment technology, turning conventional processing stations into flexible areas with mobile machines for various design processes: geometric data acquisition, definition of target positions, milling or optimisation of sections. Thus, designers have the freedom of movement and an undisturbed view of the product as opposed to the classic design centre with stationary milling machines and horizontal measuring arms that offer limited possibilities, the company added.
Also, 3D Arena can theoretically consist of any number of Move-Inspect cameras mounted on a highly stable camera frame outside the designer’s focus (e.g. ceiling-mounted), the supplier noted. Therefore, the space required will be reduced. A 16-camera-configuration, for example, covers a measuring field of about 6 m x 8 m and is suited for work with design models, like in automotive development. Besides capturing the position of the model, the camera system acquires the position of a mobile milling machine, a 3D scanner or other instruments. It determines their position and orientation in the working space of the model.
Measurements are automatically transformed into the object coordinate system. The supplier said that if the milling machine is put aside and brought back after a break, the tracking system recognises it and sets up the processing programme according to the coordinates. The user receives precise results, even when interrupted, the company claimed.
Moreover, this arena technology offers applications beyond design: positioning and alignment of different objects or components, also during assembly or production, probing tasks and large deformation analyses. Targeting of the object is not required for all applications. The company added that the Breuckmann navi Sca is a compatible scanner and is adapted to the 3D Arena and requires no targeting.
