Fundamental Studies in the Use of Sonic Power for Rock Cutting

Autor: Karl F. Graff

Preliminary studies in the penetration of rock faces with tools which are driven by sonic transducers, are reported in the system development section of this report. The high-power sonic transducers, which were developed in previous research programs
