NEW IAF-PP PROGRAMME WORK Surface Enhancement of AM Components by Laser- assisted Robotic Hammer Peening 1PACKAGE The main objective is to develop a cost-effective laser-assisted robotic hammer peening as a hybrid process which overcomes the limitations of conventional hammer peening. Using an ultra-fast laser, surface is heated up in-situ during robotic hammer peening in order to augment the process capability, specifically to achieve deeper and more stable compressive residual stress. Improved formulation for coating layer will also be developed by SIMTech. Potential applications are in both large area treatment and also localized repair. WORK Internal and External Finishing of AM Components 2PACKAGE In this Work Package, abrasive flow machining (AFM) and robotic stream finishing (RSF) are developed for internal and external finishing of AM components respectively. Modeling and simulation capabilities will also be developed to support complex process planning and control for AFM and RSF. Finally, a new electropolishing method, with a novel electrode for polishing of complex internal geometry, will also be developed as an alternative to AFM. WORK Non-destruction Evaluation of AM Components 3PACKAGE Non-destructive Evaluation (NDE) techniques are developed to address the requirement from the other Work Packages. Electromagnetic and ultrasonic techniques will be developed to quantify residual stress and characterise near-surface microstructural change. X-ray CT algorithms will be developed to accurately measure the surface roughness, internal dimension and near-surface defects, while ultrasonic techniques will be investigated for online monitoring of surface finishing process with the potential to be integrated as a system with closed-loop feedback.

MEMBERS' CAPABILITIES Reverse Engineering with Hexagon VISI 2020 Reverse Engineering (RE) is a viable method to reconstruct 3D CAD models of existing physical parts. The 3D scan data, in point cloud format, is transformed to produce a boundary-representation CAD model using commercially available RE software. Recovery of such a 3D CAD model provides information for legacy parts or CADs that are unavailable. The ARTC Intelligent Product Verification (IPV) team undertook a study of several offerings, one being the VISI Reverse 2020 CAD/CAM software, by our member Hexagon Manufacturing Intelligence. A representative aerofoil was scanned with a structured light-based 3D scanner. The steps to convert a 3D point cloud to a 3D CAD model are shown below. Through reduced dependency on manual input from the operator, the time taken for RE was 30% shorter compared to standard commercial RE softwares based on the specific part used. Overall, the RE process is systematic and user-friendly and the team plans to apply VISI reverse in relevant projects moving forward. Differentiating Features of VISI reverse • User-interface with step by step functions with guide • Direct Modelling enabling user to quickly create and modify any geometry.
