摘要： 通过SiCW-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方证据和机理，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。

关键词: 铝复合材料, 切削变形, 楔形积屑瘤

Abstract: The law of chip deformation is verified by cutting experiments of SiCw-LD2, SiCp-LD2 reinforced aluminum composites. The chip bottom photos of metapllograh and SEM prove the producing mechanism of wedgy built-up edge (BUF). It is first put forward that reinforced aluminum composites wedgy BUE is basically different from carbon steel BUE in both the producing profiles and mechanism.

Key words: Cutting deformation, Reinforced aluminum composite, Wedgy built-up edge
