Repair process planning and simulation

Once a damaged part has been delivered to the repair site, there are two main steps which need to be taken:

  • determine the repair geometry (ie the size and shape of the damaged region
  • work out the toolpath for the additive manufacturing head

Within AMOS, partners have developed a benchmark test for scanning equipment. This was tested using Liburdi's scanner to ensure that the types of damage being studied in the project could be recognised.

Students at McGill have created a software tool for analysing and reconstructing the damaged area and validated it on real, industrial components provided by the partners. This work has been published as a thesis.

A process planning and simulation system has also been created. A high-level planner creates the repair toolpath which is translated into machine-specific code by a post-processor. The process planner can be used to increase build reliability and predict the resultant build quality.
