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。 In this paper, we discuss a cloth piece algorithm of the composite diamond bit, which is based on the principle of equal cutting, that is, the cutting amount of each tooth of the composite diamond bit is equal or approximately equal during the drilling, , Extend drill life, improve drilling efficiency purposes. In this paper, combining engineering practice, analysis and calculation accuracy, generating engineering data sheet, and finally by the computer to calculate and draw bit gear, has some practical significance.
