| 摘 要： | 详细讨论了各种因素对PDC钻头切削齿的两个工作角(前倾角及侧倾角)的大小和方向的影响-根据PDC钻头的结构特点,在设计切削齿工作角时,将钻头分为四个区域,分别论述了各个区域切削齿工作角的设计方法和原则.研究认为,控制钻头各部位切削齿结构参数的变化,可以设计出满足要求的切削齿工作角.

| Abstract: | This paper discusses the influences of various factors on the back rake angle andthe side rake angle-two working angles of a PDC bit cutter. According to its structuralfeatures, a PDC bit is divided into four parts in designing cutter working angles. The design principles and methods of cutter working angle for each part are introduced. |
