通过ＳｉＣｓｓ－ＬＤ２（ＳｉＣｐ－ＬＤ２）铝复合材料的切削试验，论述了切削变形规律。通过切屑根部标本金相照片和扫描电镜ＳＥＭ照片，提供了生成楔形积屑瘤的有力证据和机理，并首次提出了无论从形貌还是从生成机理上看，铝复合材料的楔形积屑瘤与碳钢的鼻形积屑瘤都有着很大的不同点。
Through the cutting experiment of SiCss-LD2 (SiCp-LD2) aluminum composite, the cutting deformation rules are discussed. The evidences and mechanisms of wedge-shaped BUE are provided by the metallographic photographs of the root of the chip and the SEM photographs of the SEM, and the first time that the wedge-shaped BUE and the Carbon steel nose Bian Tumor has a very big difference.
