The December/January issue of “Máquinas e Metais” digital is online. Check it out on page 16 the article “Statistical analysis of a mathematical model for EDM process”, where researchers present a theoretical model of the physical quantities involved in the machining process, such as electric current, electric voltage, material characteristics, geometry of the current action region and heat generated. The objective is to understand the thermophysical phenomena of the process, aiming at its improvement. Read in the “Opinion” section the article “Cybersecurity, a strategic pillar in industrial operations”, showing that small and medium-sized companies, including those in the machining sector, which exchange information about production intensively, must be aware of the risk of cyberattacks, which can compromise their routines and results. Furthermore, in the “Notes & Information” section, news about technology and the machining market. This issue also brings the update “Clamping Cutting Tools”, “Rotary Burr” and “Chucks for Lathes” buyers’ guides.
