The August/September issue of “Máquinas e Metais” digital is online. This edition brings, on page 16, the article “Comparative study of the cutting force via practical experiment and simulation in the turning of SAE 1045 steel”, work that presents a comparative study of the cutting force during the turning of SAE 1045 steel, through practical experiments and simulation via the element method finite and two-dimensional orthogonal cutting model, with the objective of verifying the magnitudes of cutting force responses, both from experimental results and from simulation. See on page 26 the news “Metalurgia brings together foundry and steelmaking professionals in Joinville”, a preview of the 12^th International Exhibition and Congress of Technology for Foundry, Forging, Aluminum and Services – Metalurgia 2023 (September 19^th to 22^nd in Joinville, SC), showing some of the products and services to be presented at the exhibition. Furthermore, in the ”Notes & Information” section, news about technology and the machining market. This issue also brings the update “High-speed machining heads”, “Cutting fluids” and “Diamond inserts” buyers’ guides.
