  • Cutting Forces and Tool Wear Patterns in Five-Axis Milling

    Five-axis milling is widely used in machining of complex surfaces parts. Part quality and productivity are extremely affected by cutting force and tool wear especially thin-walled complex surface such as turbine blade. Although extensive research has been conducted on cutting force and tool wear in 3-milling process very few are on 5-axis milling and bull-nose mills.
