摘要：
The fore-angle and the lateral-rotation angle of PDC core bits, which are two main geometric parameters, have an important influence on the cutting efficiency and performance. Previous studies determined the ranges of two angles mainly depending on the effect of broken rock rather than its mechanical strength to examine the issue. Based on the strength factors, the paper uses finite element program ANSYS to optimize the fore-angle and the lateral-rotation angle of PDC cutters. The main geometric parameters are optimized and the optimal values are obtained under different circumstances, which provides a theoretical basis for reasonable design of the PDC core bits.
