摘要： In a machine tool which includes a rotary shaft configured to allow a tool or a workpiece to be attached thereto, a driving unit for causing the rotary shaft to rotate is regulated to change a rotation speed of the rotary shaft in such a manner that the rotation speed oscillates with a given amplitude and a given period with respect to a given mean rotation speed, so that chatter vibrations can be suppressed. A parameter display control unit configured to cause a display device to display parameter information related to predetermined parameters for changing at least one of the mean rotation speed, the amplitude and the period is provided so that the parameters can be changed based upon the parameter information displayed in the display device.

摘要： A calculating member carries out Fourier analysis of a vibrational acceleration to calculate a maximum acceleration and frequency thereof. The calculating member then compares the maximum acceleration with a threshold value, and when the acceleration exceeds the threshold value, the calculating member calculates a k-value and phase information, and stores each calculated value. When retrying is selected, the calculating member determines a type of a current chatter vibration from the phase information, determines the existence of a chatter vibration which is different from the determined chatter vibration, and calculates each new phase information according to the determined chatter vibration and an existence of a different chatter vibration which had been generated before generation of the current vibration. The calculating member then calculates a k1-value from new phase information, calculates the optimum rotation speed by using the k1-value, and changes the rotation speed to the optimum rotation speed.

摘要： An elliptical vibratory cutting apparatus includes a control mechanism which applies a sinusoidal voltage having a predetermined phase difference to piezoelectric elements. Flexure vibrations are accordingly generated in X and Y directions. The vibrations in the X direction cause interference with the vibrations in the Y direction and vice versa. An amount of interference, caused by vibrations in one direction, with vibrations in another direction, is correctively eliminated by the control mechanism (interference eliminating unit. A workpiece is thus cut by means of a cutting tool through elliptical vibrations with high precision.
