Cold spray technology offers many possibilities for manufacturing complex and freeform metallic parts with a high deposition rate, and it stands out as a potential candidate in rapid manufacturing. However, the current process lacks control over the geometrical shape, which tends to present defects that can be amplificated/propagated during the process. This fundamental problem necessitates a control system with real-time monitoring for consistent geometrical accuracy. So, the research will focus on detecting, measuring, validating, and representing the defects in real-time. Furthermore, the research will explore how to use the information to implement a control strategy by optimising parameters and toolpath planning to amend those defects and obtain the desired shape
This project is conducted in conjunction with CSIRO.
