Abstract

PURPOSE:To prevent the sensitivity of an amplitude measurement from decreasing when the vibration body is a cutting tool by outputting a signal of prescribed frequency by a frequency adjusting device according to the oscillation frequency of an oscillator. CONSTITUTION:The vibration body such as the cutting tool 2 is vibrated by the oscillator 5 through a vibrator S, the oscillator oscillation frequency of 20kHz is counted by a counter K, and the signal of prescribed frequency of 20,001Hz is outputted by the frequency adjusting device 6 according to the oscillation frequency of the oscillator 5. Then an intermittent light emitting device such as a strobe light 7 is made to blink according to the output of the frequency adjusting device 6 to project the intermittent light of the intermittent light emitting device on the vibration body, which is observed with the eye E through a microscope 8. In this case, the oscillation frequency is counted by the counter K, so the vibration frequency of the cutting tool 2 can be read directly. Consequently, when the vibration body is the cutting tool, the sensitivity of the amplitude measurement is prevented from decreasing.

Next, to explain the operation, the oscillator 5 generates 20KH.
Since the cutting tool 2 vibrating at z is made to blink at 20001H2 by the strobe light 7 via the frequency adjuster 6, the light from the strobe light 7 changes its intensity to the cutting tool 2.
