【摘要】 刀具磨损是机械加工过程中普遍存在的一种自然现象,研究了刀具磨损状态对已加工表面质量的影响,主要是后刀面磨损量对工件表面粗糙度、残余应力和加工硬化的影响,同时也探讨了切削速度与表面粗糙度的关系,并对这些影响产生的机理进行了讨论。更多还原

【Abstract】 Tool wear is a natural phenomenon in the machining processes.The influences are resea-rched between tool wear condition and machined surface.The main influences include part surface roughness, residual stress and work hardening. At the same time, the relation is studied between cutting speed and surface roughness. The mechanism production of these effects is also discussed.更多还原
