Abstract
In-situ measurements of tools allow inspecting a running metal forming process. This enables a fast adaption of the process and helps reducing costs. However, the requirements on the measurement systems are high, as the measurement duration needs to be low and the available space inside the machines is limited. Commercially available measurement systems are unable to operate in these conditions. An application in metal forming is presented followed by the introduction of a novel design for an optical measurement system based on the fringe projection profilometry technique. The new design employs flexible fiber bundles to transport the images of the fringe projection system to a compact sensor head which is based around gradient-index lenses. The pattern generation unit and camera are housed in a base unit, which can be placed outside of the machine. While this new approach allows flexible positioning of the sensor head, it creates challenges for the pattern evaluation algorithms and the optical design of the system. The laser-based optical setup will be presented followed by measurements of the tool of the aforementioned forming process. To evaluate the applicability of the new measurement system, the determined tool parameters will be compared to reference measurements obtained by a tactile Hommel T8000 system. In combination with a positioning device, which is currently being developed, the new measurement system will be used to obtain wear information of the running forming process in order to control the process quality loop in the future.
