Abstract
An ultrasonic tool system with a console and a tip that has a distal end that when vibrated vibrates both longitudinally and torsionally. The console applies a drive signal to the drivers that vibrate the tip that is at a longitudinal mechanical cancellation frequency. Consequently, when the tip is vibrated, at the distal end the longitudinal component of a first resonant mode of the tip cancel out the longitudinal component of the second resonant move of the tip so the distal end of the tip engages in vibrations that substantially torsional and only minimally longitudinal.
