Fundamental Studies in the Use of Sonic Power for Rock Cutting

Abstract

The utilization of high power, high frequency sonic transducers for rock cutting has been in progress at Ohio State University for two years with the second year of work presented in this report. Two modes of rock cutting were investigated; the first, simple drilling and the second, layer cutting. An impact coupling technique, which utilized a small, bouncing cutting tool at the tip of the transducer, was used in both modes of cutting. The overall study was divided into a system developed phase, where laboratory cutting apparatus was tested, and a system analysis phase, where basic studies of sonic processes and devices were carried out.
