A cutting apparatus includes a cutting tool having a cutting edge, an excitation part structured to apply excitation to the cutting tool, and a drive part structured to apply a voltage to the excitation part to reciprocate the cutting edge of the cutting tool. The excitation part suppresses residual oscillations by applying excitation that contains an excitation force of components of frequencies higher than a resonance frequency and has an excitation force of the resonance frequency suppressed. The excitation part applies a first excitation, and applies a second excitation after an elapse of a time 0.5 times as long as a resonance period from timing at which the first excitation is applied to suppress residual resonance oscillations.

An input voltage control device including a first power line inputted with a voltage of 300V to 380V and a second power line inputted with a voltage of 0V. The potential difference between the first power line and the second power line is variable. A constant voltage generator outputs a constant potential voltage of (24V, for example) to a third power line. A reference potential generator outputs a reference potential of (10V, for example). A comparative potential generator outputs a comparative potential which is within the range of (0V to 24V, for example), based on the input voltage. A comparator outputs to an NMOS transistor a conducting potential voltage of (24V, for example) or an interrupting potential voltage of (0V, for example) depending on the comparison between the reference potential and the comparative potential. When the comparator outputs the conducting potential, the path between the source and drain of the NMOS transistor is made conductive.

[SOLUTION]

For example, a first power line L1 (a terminal T1) is inputted with a voltage of 300V to 380V and a second power line L2 (a terminal T1) is inputted with a voltage of 0V. The potential difference between the first power line L1 and the second power line L2, or input voltage Vin, is variable. A constant voltage generator 2 outputs a constant potential (voltage of 24V, for example) to a third power line L3. A reference potential generator 3A outputs a reference potential of 10V, for example. A comparative potential generator 4A outputs a comparative potential which is within the range of 0V to 24V, for example, based on the input voltage Vin. A comparator 5 outputs to an NMOS transistor 6 a conducting potential (voltage of 24V, for example) or an interrupting potential (voltage of 0V, for example) depending on the comparison between the reference potential and the comparative potential. When the comparator 5 outputs the conducting potential, the path between the source and drain of the NMOS transistor 6 is made conductive. When the comparator 5 outputs the interrupting potential, the path between the source and drain of the NMOS transistor 6 is made non-conductive.
