摘　　要：本文讨论一种复合片金刚石钻头的布齿算法,该方法的依据是等切削原理,即在钻进过程中复合片金刚石钻头每个齿的切削量相等或近似相等,可望获得各齿均匀负荷、延长钻头寿命、提高钻井效率的目的。文中结合工程实际、分析计算精度、生成工程数据表,最后由计算机实现计算和绘制钻头布齿图,具有一定的工程实用意义。An algorithm of cutter placement on the PDC drill bit by using computer-aided drafting is discussed in this paper. The algorithm is based on equal quantity cutting in order to keep the some quantity cutting by each cutter thus the life of the bit can be extended. Method of calculating the co-ordinate values is discussed with practical projects. Calcudation accuracy is analysed and the generation of the mould and of line-drawign data table is described.
