摘要:

本文系统地研究了PDC钻头各几何结构参数之间的关系,在不作几何假设和简化的情况下导出了PDC钻头几何学基本方程式,它可直接用于PDC钻头运动学、切削力学研究和钻头设计中,避免了由几何假设和简化带来的计算误差。

Abstract:

This paper systematically studies the relationship of the geometric structural parameters of PDC bits, and derives the essential equations of PDC bits geometry without making any hypothesis and simplification. The essential equations can be directly applied to the studies of PDC bits kinematics and cutting mechanics, and the bit design, eliminating counting errors caused by geometric simplifications.

Key words: PDC bit, Geometry, Kinematics, Bit design
