结合超精密切削的工艺特点,在分析超精密切削积屑瘤现象及成因的基础上,通过研究切削用量、刀具几何参数、切削液、刀具刃磨等因素对积屑瘤的影响机理,分析积屑瘤对超精密切削加工表面粗糙度、切削力和切削变形、切削振动的影响,并提出超精密切削条件下抑制积屑瘤的主要方法。 Combining with the characteristics of ultra-precision cutting technology, based on the analysis of the phenomena and causes of BUE of ultra-precision cutting, the mechanism of BUE is studied through the research on the influence mechanism of cutting dosage, tool geometry, cutting fluid and tool sharpening on BUE, The influence of the surface of the ultrafine cutting machining on the surface roughness, cutting force, cutting deformation and cutting vibration of the ultrafine cutting was studied. The main methods of restraining BUE on the ultra precision cutting were put forward.
