Calibrated FEM modelling of rock cutting with PDC cutter [PDF]
MATEC Web of Conferences, 2018 Complexity of bit-rock interactions and formation fracture makes rock drilling a challenging task from modelling perspective. A finite element model is developed which can plausibly capture the rock fractures while it is capable of evaluating drilling forces for various values of Rate of Penetration (ROP), bit angular velocity and cutter configuration.

Research on Cutting Load and Heat Generation Law of PDC Wearing Cutter
Shiyou jixie, 2021 At present, there is no further researches on the cutting load and heat generation of worn PDC cutter under different front rake angles and different wear grades. For this reason, single cutter cutting tests are used to verify the relevant performance of

Experimental Study on Force of PDC Cutter Breaking Rock
Procedia Engineering, 2014 AbstractBecause the anisotropy of shale formation should result in that wellbore deviations is unpredictable, the bit-rock interaction should be fully lucubrated in order to eliminate this problem. The impact of shale rock anisotropy and the cutting velocity on the load of PDC cutter wasn’t considered by the existing cutter-rock interaction models.
