Laser-aided direct metal tooling of manufacturing aviation details on CNC machine

Abstract

This paper discusses the effectiveness of the use of hybrid technology based on Laser-aided Direct Metal Tooling with subsequent machining as an alternative to traditional methods for producing products of a complex profile for the aviation industry. The aspects of the application of Laser-aided Direct Metal Tooling in the production cycles of manufacturing products passing through the final assembly operations are considered. The paper proposes an alternative manufacturing technology through the use of Laser-aided Direct Metal Tooling at the stage of design and technological study of the manufacturing cycles of individual assembly units. The objective function of ensuring high requirements for the accuracy of the relative position of the part in the assembly, reducing the mass and dimensions of the product, which is important for modern aviation systems. A technological solution is proposed to provide technical indicators of the objective function based on combining the advantages of laser, hybrid, and additive technologies in the working area of technological equipment. Considered technical solutions for the implementation of the proposed hybrid technology in the manufacture of critical parts of the aviation industry. The aspects of the production of parts are considered from the point of view of reducing the error in the relative position of the actuating surfaces of the product, an analysis is made of the machining errors in the process of the proposed production technology, with respect to the errors arising from traditional production cycles of parts of this type.
