3D Scanning

We take on high-precision 3D scanning of your components for you. For this purpose, we use a laser scanner. In addition to the digitisation of various objects and workpieces, we can also create a target-performance comparison of your product with the 3D CAD data.

Design data is generated from the scanned point cloud in reverse engineering. 3D digitisation thus paves new paths for rapid prototyping and rapid tooling. We also create calibrator references, which enable precise calibrations of robot applications. The so-called re-teaching is thus reduced to a minimum.

Calibration by laser 3D scans

For robot-guided processing operations with a high number of waypoints, a reliable and exact concept is essential when calibrating tool and base, in order to avoid time-consuming re-teaching of the robot movements after a crash, at re-start or when replacing a robot. The downtime of the system is reduced.

For new plants, a laser calibration system from Wiest AG is used to create a calibration reference of a workpiece. For this purpose, reference marks are attached to a master part and then measured with a laser 3D scanner. As a result, the positions of the reference marks are created in relation to the operating point of the robot (TCP). The use of the resulting coordinate system enables time savings of up to 80% compared to conventional teaching of robot path movements. Due to the exact measuring process, the use of the offline-programmed trajectories is nearly directly possible. Without loss of time owed to reworking.

3D digitisation

In contrast to CAD models, actually manufactured workpieces are subject to tolerances. For example, robot grippers often must be manually reworked to compensate for the differences between the nominal and actual dimensions of the workpiece. It is difficult or even impossible for the resulting free spaces on the gripper to be documented and updated in the CAD model.

The reworked gripper is converted into a 3D point cloud by using the hand-held 3D scanner T-Scan from Zeiss along with the optical tracking system T-Track CS+. By using reverse engineering tools, this becomes a complete CAD model and thus enables perfect adaptation of the robot gripper.

This is just one of many examples of how and where 3D scans enable us to work more successfully. As there is no need for a physical connection to a measuring table, even heavy, large and already installed components can be scanned and processed.
