中文摘要:
      高性能难加工材料在高端制造业中的应用越来越广泛,关键零部件的精度要求极高,而材料的可磨削性差,对磨削加工工艺提出了严峻挑战。为了提高难加工材料磨削表面完整性,降低砂轮磨损,国内外学者开展了大量研究。全面回顾了难加工金属材料、硬脆材料以及复合材料可磨削性的国内外研究进展,包括工件表面完整性、砂轮堵塞与磨损、磨削颤振以及改善可磨削性的先进技术4个方面。对不同类型难加工材料可磨削性的特点及共性问题展开了讨论,总结了各类难加工材料加工损伤的成因,指出改善难加工材料可磨削性的主要思路是降低磨削力和磨削温度。分析了磨削力和磨削热的来源以及对表面完整性和砂轮磨损的影响,提出了基于“节源”和“开流”思想降低磨削力和磨削温度的工艺策略,并对难加工材料高质高效加工方法进行了展望,指出高性能砂轮及其修整技术、高效冷却润滑技术、多能场复合磨削技术以及超高速磨削技术的不断发展,都有利于解决难加工材料的高质高效加工难题。
英文摘要:
      High performance difficult-to-machine (DTM) materials are increasingly applied in advanced applications. The precision and accuracy requirements for key parts enhance unceasingly, but the grindability of materials with high performance is inferior, which proposes an enormous challenge to the grinding process. To improve the surface integrity and reduce grinding wheel wear, scholars at home and abroad have carried out extensive research. This study comprehensively reviews the recent research progress on grindability of DTM materials (e.g., metallic materials, ceramic materials, and composites) from four aspects, including surface integrity, grinding wheel blockage and wear, grinding chatter, and advanced technologies for improving grindability. The study first discusses the characteristics and common problems of grindability of DTM materials and summarizes the underlying formation mechanism of machining damage. It is concluded that the main strategy to improve the grindability of a material is to reduce grinding force and temperature. Furthermore, the study analyzes the sources of grinding force and temperature, and their influences on the surface integrity and grinding wheel wear. On these bases, the study puts forward a process strategy to reduce grinding force and temperature inspired by the ideas of “reducing the inflow” and “promoting the outflow”. Finally, high-quality and efficient machining methods for DTM materials have prospected. The study points out that high quality and efficient machining of DTM materials rely on the continuous development of various advanced techniques, including high-performance grinding wheel and its dressing techniques, high-efficiency cooling and lubrication techniques, multi-field hybrid grinding techniques and ultra-high-speed grinding techniques.
