摘要
本文对国外新型三维断屑槽的断屑性能进行了试验研究，探讨了三维断屑槽的结构特点及设计原理，指出采用折衷的方法设计复合式结构是扩大断屑槽适用范围的一种有效手段．
The chip performance,the structure feature and the design principles of foreign newstyle three dimensional chip breakers are experdriented and studied. It is presented in this paperthat designing the composite structures of chip breaker is a compromise method and an effective means to expand the seope of application of chip breaker.
