Analysis of Drill Failure Modes by Multi-sensors on a Robotic End Effector

Abstract

The characteristics of nine common drill failure modes have been analyzed. To facilitate detecting and diagnosing these failure modes, a multi-sensor approach is developed. Based on the dynamic characteristics of three different measurements including thrust, torque, and lateral vibration, necessary signatures are extracted for the nine failure modes. Experimental tests were conducted to confirm the characteristics of these nine drill failure modes.
