Title:
VIBRATION CUTTING APPARATUS AND VIBRATION CUTTING METHOD
Document Type and Number:
Japanese Patent JP2008068364
Kind Code:
A
Abstract:

To provide a vibration cutting apparatus improved in cutting efficiency by eliminating waste time spent for air cutting.

The vibration cutting apparatus includes: a vibration state calculation part 32 for respectively calculating a frequency, an amplitude and a phase of vibration in a first direction and of vibration in a second direction of a bite 13 in real time, based on at least one of information pieces including driving voltage values and driving current values respectively applied to a stretching vibration Langevin oscillator and a bending vibration Langevin oscillator in a vibrating tool unit 14 from a vibration control part 30, and measurement information measured by a vibration sensor 15 and a gap sensor 27 respectively; and an initial contact sensing part 33 for detecting an initial contact position of the bite 13 and a workpiece 7 when cutting, based on at least one of information pieces including the frequency, the amplitude, and the phase of vibration in the first direction and vibration in the second direction calculated by the calculation part 32.
