Independent analyses of cutting and friction forces applied on a single polycrystalline diamond compact cutter

Abstract: International audienceThis paper presents ananalysis of the excavation forces involved in the cutting action and in the frictionof a cutter/rock contact.A vertical lathe-type device provided data on the forces applied on a single cutterunder dry excavation conditions.A cutting device was used to perform cutting experiments with unwornand worn cutters.A tribometer wa sused to perform friction tests on the cutters wear flat previouslyrealized with the vertical lathe.The experiments display results conform to the… Show more

“…Therefore, it is necessary to incorporate the friction characteristic between the tool and the workpiece into the current study. By referring to the traditional calculation method, the equivalent COF is composed of the ploughing COF and the interfacial COF [37][38][39]. In this paper, a theoretical model for calculating COF was developed to investigate the friction characteristic of optical glass BK7 in nanoscratching for both edge-forward and face-forward directions.…”

“…The most common wear mechanism operating on PDC bits during rock drilling is abrasion [63,64]. This causes the formation of a flattened region on the cutter [65], and the friction on the wear flat can dissipate up to 50% of the total energy for drilling [56]. Although the hardness of diamond is considerably higher than that of the commonly encountered rocks drilled by PDC cutters, it can still be subjected to abrasion during the drilling process.…”
