Investigation into the impacts of rock/cutter interface geometry on drilling response of PDC cutters
MetadataShow full item record
This thesis investigates the effects of geometry on the cutting action of circular sharp PDC cutters. Results of extensive laboratory rock cutting experiments indicate that the force acting a cutter while tracing a groove is affected by the geometry or shape of the groove and in particular: (a) the length of the cutter edge in contact with the rock, and (b) the relative section of rock material located above the cord of the groove.

Analysis of rock cutting process with a blunt PDC cutter under different wear flat inclination anglesRostamsowlat, I.; Akbari, B.; Evans, Brian (2018)It is generally accepted that drilling with drag bits (Polycrystalline Diamond Compact bits) simultaneously consists of “pure cutting” and “frictional contact” processes. To date, the mechanics of rock cutting have been ...
Experimental investigation on the effect of wear flat inclination on the cutting response of a blunt tool in rock cuttingRostamsowlat, I.; Richard, T.; Evans, Brian (2018)A vast majority of experimental researches focuses on the cutting action of a sharp cutter, while there has been limited experimental work devoted to the study of the contact process at the wear flat-rock interface.
