Turning SAE4140 steel using coated carbide inserts

Today's industry demands development in manufacturing processes, especially with more modern and efficient machine tools, and the constant improvement of cutting tools. Choosing the right cutting parameters and the right cutting insert is a matter of keeping up with technology in order to reduce costs and increase the final quality of the products manufactured. The work carried out evaluated the cutting speed parameter of coated carbide inserts in the SAE4140 steel roll turning process. It was concluded that fracture and chipping of the cutting edges were predominant when using high cutting speeds. It can also be observed and emphasised that in the turning process of materials with high hardness, carbide-coated inserts have better performance in the machining of materials with high hardness and good performance in relation to wear.
