Enhancment of Wire Arc Additive Manufacturingproduction of Aluminum Part

Abstract

The article provides original findings of the improvement of the production of the wire arc additive manufacturing of aluminum. The simulation of the process of wire arc additive manufacturing of a three-level hierarchical model was carried out, while taking into account the requirements for manufacturability and quality of the obtained part, such as its geometric dimensions, residual stresses and maintaining of the optimal production speed. During the occurrence of problems with heat distribution, various trajectories of movement and topologies were used to solve them. The optimal trajectory and print pa-rameters are created in the form of temperature control for the specified part. Implemented the ability to use a telecommuni-cation feedback system using telecommunication devices such as pyro camera andinfrared temperature laser sensors to mon-itor temperature during problems detected by print simulation. The obtained data were used for the further possibility of generating an automated program for controlling the robot during the additive manufacturing process. Residual stresses and the possibility of defects in the manufactured part are determined. Based on the obtained data, the values of residual stresses and defects in the manufactured parts were determined.Improved print topology using a three-level hierarchical system. Introducing the use of laser sensors and thermal cameras to the telecommunications system of additive manufacturing using wire arc welding with the improvement of the direct printingprocess by means of controlling the spread of heat.
