CAPP for Hybrid Additive Manufacturing.

Abstract : Hybrid additive manufacturing (HAM) is becoming increasingly important to obtain end-use products. However, a couple of problems still exist in all the stages of HAM’s processing chain and this thesis reports the studies on process planning. The whole research proposes some methods for three key tasks of process planning in HAM at a relatively general level. The main proposed methods include generation and optimization of the initial volume, sequence planning, and path planning. To demonstrate these proposed methods, a set of numerical simulation cases are used for demonstration. A special HAM process, cold spraying with CNC machining, is adopted to set the application requirements and manufacturing constrains in computation. However, the objective of this research is to develop generic methods for more HAM processes, where multi-axis systems are applied. By changing the manufacturing constraints, the proposed methods and implemented algorithms could be adopted for wide CAPP applications in different HAM processes.
