已加工表面上的鳞刺对加工质量影响很大,而有关鳞刺形成的机理一直存在着争论。国外学者一般认为鳞刺是由于积屑瘤脱落在已加工表面上而形成的。可是,在极低的切削速度下没有积屑瘤却仍有鳞刺又该如何解释呢?周泽华教授提出,鳞刺是经过在切屑根部产生“导裂、层积和刮顶”等几个阶段而形成的。 The scale on the machined surface has a great influence on the processing quality, and the mechanism of the formation of the scale has been debated. Foreign scholars generally believe that the scale is due to the built-up edge tumor has been processed on the surface and formed. However, at very low cutting speeds, there is no BUE but there is still a spines and how to explain it? Professor Zhou Zehua proposed that the spines are generated in the chip root “cracking, stratification and scraping the top” and several other stages And formed.
