    摘要: Apparatuses and methods for adjusting weight-on-bit/torque-on-bit sensor bias in a drill bit. The apparatus may include a bit adjustment device disposed at least partially in a cavity in a bit shank. The bit adjustment device includes electronics and sensors for estimating a weight-on-bit/torque-on-bit bias. The method includes adjusting the weight-on-bit/torque-on-bit sensor bias of a drill bit. The method may include adjusting force on a bit adjustment device to adjust weight-on-bit/torque-on-bit sensor bias. The method may also include securing the bit adjustment device within the cavity of the bit shank after the desired weight-on-bit/torque-on-bit sensor bias has been achieved.
