Abstract
In one aspect, a method of making a drill bit is disclosed that includes selecting a drill bit configuration, obtaining a stress map for the drill bit configuration relating to a drilling operation, performing a mechanical test with an actual drill bit having the selected configuration, and selecting a location on a surface of the drill bit for installing a sensor thereat based on a location of low stress from the stress map and results of the mechanical test, and placing a sensor at the selected location.
