Method of making imbalanced compensated drill bit
Description
This patent describes a method for making a drill bit of the type having a bearing zone on a side portion of a bit body and a cutting zone with cutters mounted on the bit body. It comprises: mounting a preselected number of cutters within the cutting zone on the bit body; generating a model of the geometry of the bit body and cutters mounted thereon; calculating the imbalance force which would occur in the bit body under defined drilling parameters; using the imbalance force and model to calculate the position of at least one additional cutter which when mounted within the cutting zone on the bit body in the calculated position would create a net imbalance force directed towards the bearing zone; and mounting an additional cutter within the cutting zone on the bit body in the position so calculated
