Precision Machining of Hard-to-Cut Materials: Current Status and Future Directions

Machining difficult materials like superalloys, ceramics, and composites is fundamental in industries where performance is paramount, such as the auto industry, aerospace, and medicine. These materials with relatively high strength, hardness, and high-temperature capabilities pose difficulties in machining, thus calling for improved precision machining technologies. This survey paper presents a detailed review of the current state of the art of precision machining of these difficult materials, along with advances observed in tools for cutting, machining techniques, and new technologies. They range from carbide, ceramics, super hard tools, and geometry of tools, and this topic also deals with tool coatings. The article also discusses specifics of the traditional and nontraditional machining processes: turning, milling, electrical discharge, and laser machining, as well as the relations between additive and hybrid manufacturing. The importance of new technologies or digital and intelligent manufacturing systems in enhancing the accuracy and productivity of machining is also illustrated. Furthermore, the paper also provides information on how digital and intelligent manufacturing technologies can enhance machining efficiency and accuracy. Moreover, future research will aim to minimize tool wear, enhance surface finish and integrity, and environmentally conscious machining. The paper concludes with a hopeful note on the potential of future research to revolutionize the precision machining industry, offering high performance and reliability in critical applications while maintaining a focus on sustainability.
