Machining advanced materials presents significant challenges due to severe tool wear and high cutting forces. This paper discusses emerging technologies such as selective melting, laser-assisted machining, and diamond wire saw machining, which offer promising solutions for effectively cutting these materials while maintaining precision and surface integrity. Advancements in micro milling techniques also contribute to machining difficult-to-cut materials. Challenges associated with superalloys, composite materials, and ceramic matrix composites include high tool wear and intricate material removal mechanisms, leading to surface defects.
