Methodology for Designing a Laser-Based Additive Process for the Formation of a Lattice Periodic Structure on the Surface of an Aluminum Alloy Plate

The paper presents the results of studying the “directed energy deposition” additive technological process aimed at improving the mechanical properties of thin-walled parts made of AMg3 aluminum alloy sheets by creating a lattice structure of AK4-1 aluminum alloy on their surfaces. Based on the results of mathematical modeling of the process of propagation of thermal fields formed in the region of interaction of laser radiation with the processed material, the parameters of the laser beam and the velocity of its motion are determined. Software has been developed that implements numerical calculations for the presented mathematical model of the additive process. A scheme is proposed for remote interaction of an intelligent service for decision support by operators of an additive manufacturing system with the created software. The obtained results of numerical calculations in the Wolfram Mathematica system, as well as expert information accumulated in the knowledge portal of the IACPaaS cloud platform, are promising for training and decision-making by operators of laser technological equipment.
