A new structure is proposed to solve the failure mode of PDC cutter created by its mechanical fatigue, crack and diamond table delamination, so as to improve their service life. By applying the finite element method analysis, the force allocation of PDC cutter and multi-face (as known non-planar) designed PDC reinforced-cutter revealed that: the distribution and size of the internal stress in the cutter when working was improved, and the multi-face structure further reinforced the meshing force of the cutter’s PDC layer and cemented carbide substrate. And thus significantly strengthen the shear-resistance capability. This is particularly meaningful to the kinematics of mono-cone bit and its adaptive exploration of rock-breaking features, as well as to the related scientific disciplines in the future.
