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
