Abstract
The use of additive manufacturing (AM) has increased significantly in recent years, mainly for small components and pieces with complex geometry that cannot be manufactured through conventional processes. One of the problems of this technology is the poor surface roughness. The application of a secondary process, such as machining, improves the surface finish, and it’s necessary in most cases. The objective of this study was to investigate the effect of different types of cutting fluids on the machined surface roughness of components produced through AM and conventional rolling processes of AISI 316L. A carbide tool was used during the milling process, and three types of cutting fluids were used: dry machining, flooded cutting fluid, and cryogenic cooling. The surface roughness was measured using a laser interferometer microscope. The surfaces were also analyzed through Scanning Electron Microscopy (SEM). The best results for surface roughness were achieved with the use of cryogenic cooling, with SEM revealing the presence of adhered material particles on the surface. This study provides valuable insights into the impact of the cutting fluid type on the quality of the surface of machined components produced through AM and conventional rolling processes.
