Abstract

A prototype of a motion control system for an Ultrasonic Planetary Core Drill (UPCD) tool is presented. This system is designed to maintain a consistent dynamic behavior in the ultrasonic horn/free-mass/drill bit stack during ultrasonic-percussive drilling into a range of non-homogeneous rocks. The control system is a simple negative feedback loop which employs the output of the P100 control unit (manufactured by Sonic Systems Ltd) that powers the ultrasonic transducer, ensuring that the drill tool is advanced while a steady ultrasonic vibration level is maintained. This paper describes the mechanical design of the test rig, the control system design and an evaluation of its performance.
