The study evaluated how well coated cemented carbide inserts perform when milling high-strength 508III steel. By conducting experiments and simulations, the researchers analyzed how different milling parameters affect insert failure. They also looked into the reasons behind insert wear and fracture. The study found that the type and thickness of the coating on the inserts can impact their wear behavior while cutting the steel. This research can help improve the durability and lifespan of coated cemented carbide inserts used in processing nuclear power components.
