ABSTRACT:
A precisely controllable cut is made in a workpiece by ultrasonic equipment including a horn or other element which is vibrated at ultrasonic frequency along a predetermined axis, and which carries a cutter mounted for vibration with the horn along the axis, with the cutter having a leading cutting edge disposed at an angle of between about 30 degrees and 40 degrees (preferably between about 33 degrees and 37 degrees), with respect to the specified axis of vibration. The cutting edge should desirably be disposed approximately perpendicularly with respect to the surface of the workpiece as the cut is made, the preferred angle with respect thereto being between about 85 degrees and 105 degrees.
