A kinematic simulation software for additive manufacturing metal deposition processes

Abstract : This paper proposes to define a kinematic simulation of the DMD process to predict the evolution of the real velocity (V) of the nozzle, the main parameter of the process control with the laser power (P) and the powder flow (F). Beyond the production time, the kinematical model allows to detect deceleration zones, which are likely to present excess material leading to the appearance of porosities. The proposed approach is generic enough to apply to any type of machine and allows to simulate movements with limited acceleration or limited jerk. The approach makes it possible to process very long trajectories commonly observed in this process.
