Abstract Friction at cutting interfaces deteriorates the nascent surfaces and influences the wear of tool (tool life) that causes the cost of manufacturing. Hybrid cooling/lubrication has been used to machine Nimonic 80A which is challenging to machine conventionally due to its poor heat diffusivity and superior chemical attraction. The focus was on the surface modification (roughness, topography, residual stress, microhardness) and wear phenomenon of the tools under the hybrid cryogenic minimum quantity lubrication (CMQL) approach. Compressive residual stress, increased microhardness (4–9%), and less tool wear (22–71%) were few benefits of CMQL compared to the traditional approach. Concurrent action of chilling and lubrication enabled lower temperatures, higher compressive residual stress, microhardness, and surface quality. Abrasion and adhesion were dominant wear modes.

混合润滑下铣削 Nimonic 80A 的表面改性和刀具磨损研究

摘要 切削界面处的摩擦会破坏初生表面并影响刀具的磨损（刀具寿命），从而导致制造成本。混合冷却/润滑已被用于加工 Nimonic 80A，由于其较差的热扩散性和优异的化学吸引力，这对传统加工具有挑战性。重点是在混合低温最小量润滑 (CMQL) 方法下工具的表面改性（粗糙度、形貌、残余应力、显微硬度）和磨损现象。压缩残余应力、增加的显微硬度 (4-9%) 和更少的工具磨损 (22-71%) 与传统方法相比，CMQL 的好处很少。冷却和润滑的同时作用能够实现更低的温度、更高的压缩残余应力、显微硬度和表面质量。
