Summary. In this paper, we integrated our polycrystalline diamond compact (PDC) cutter model ( Chen et al. 2021) into a PDC bit model that can predict the weight on bit (WOB), torque on bit (TOB), and imbalanced side force on a bit under given drilling conditions. We first proposed a method to determine the actual cutting plane and depth …

Abstract: . The technology for the mechanical excavation of low to medium strength rock has been substantially well developed, and therefore it has been used in most cases as an alternative technology to drill and blast excavation (Gertsch, 1994). However, in the case of hard rock excavation, especially for mining excavations, such …
