The Collaborative Robotics Laboratory of the University of Coimbra is an essential member of the INTEGRADDE consortium, developing technologies that facilitate the integration of the different stages of the project, namely:
- Generation of robot paths for metal additive manufacturing;
- Simulation of robot activity.
The additive manufacturing process commonly starts with the Computer-Aided Design (CAD) model of the part to produce. Such CAD models are the basis for providing a set of processes conducting to the production of the part. The University of Coimbra is working on an integrated CAD-to-part methodology featuring part decomposition, path planning, robot motion simulation and generation of the robot code. We are working to automate these processes, a challenging task in face of the complexity of the parts to produce.
An important keyword here is interoperability. Many times, there is no standard data formats for data exchange between the heterogeneous engineering tools used in additive manufacturing, from CAD, to CAM, to FEA, to machine/robot simulators. We are working on integrated and interoperable AutomationML-based platforms for the robotic process of metal additive manufacturing.
Such a technology allows us to share and edit process data and parameters along the different sub-stages of the process. The AutomationML neutral data format allows the implementation of optimization loops connecting different sub-stages, for example, the multi-physics simulation and path planning.
