Abstract
Official abstract text for this publication.
An earth boring drill bit designed for a specific performance, within a finished product tolerance, using components built to a looser manufacturing tolerance. The bit may be assembled by selecting a leg from a plurality of pre-manufactured legs; selecting a bit body from a plurality of pre-manufactured bit bodies, the bit body having a slot for receiving the leg; placing the leg within the slot; and fixing the leg within the slot within the finished product tolerance by placing one or more shims between the leg and the slot. The shims may be used to adjust an axial position, a radial position, and/or a circumferential position of the leg with respect to the slot. The leg and the bit body may be selected, or produced, to ensure the bit will not meet the specification, given the manufacturing tolerance, without the shims.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of assembling an earth boring drill bit to meet a finished product tolerance relative to a desired aggressiveness of the finished drill bit using components built to a manufacturing tolerance, the method comprising the steps of: selecting a bit body from a plurality of pre-manufactured bit bodies, the bit body having one or more axially extending slots; selecting one or more legs from a plurality of pre-manufactured legs, the one or more legs incl…
