Machinability Investigations Based on Tool Wear, Surface Roughness, Cutting Temperature, Chip Morphology and Material Removal Rate during Dry and MQL-Assisted Milling of Nimax Mold Steel

Using cutting fluids is considered in industrial applications and academia due to their increased influence over many aspects such as machinability, sustainability manufacturing costs. This paper addresses the machinability perspective by examining indicators roughness, temperature, tool wear chip morphology during milling of mold steel. A special type steel Nimaxm which a difficult-to-cut material because its high strength, toughness, hardness resistance. Since steels have reverse geometry components produced this technology, surface quality dimensional accuracy are highly important. Therefore, two different strategies, i.e., dry minimum quantity lubrication (MQL), were chosen conduct an in-depth analysis performance at speeds, feed rates depths. Without exception, MQL technology showed better than condition obtaining roughnesses under parameters. Despite that only small improvement was achieved terms found be successful protecting from excessive amounts chips. anticipated guide for manufacturers researchers area presenting capabilities sustainable machining methods.
