Abstract
A rotation controller controls a rotation mechanism for rotation of a spindle. A movement controller causes, while the spindle is rotating, a feed mechanism to bring a cutting tool into contact with a workpiece to cause the cutting tool to cut the workpiece. The rotation controller controls a spindle rotation speed so as to accelerate or decelerate the rotation of the spindle, and the movement controller brings the cutting tool into contact with the workpiece after the rotation controller starts the rotation of the spindle, and separates the cutting tool from the workpiece while the spindle rotation speed is put under the acceleration control or deceleration control exercised by the rotation controller.
Claims5
A machining apparatus comprising:
- a rotation mechanism configured to rotate a spindle to which a cutting tool or workpiece is attached;
- a rotation controller configured to control the rotation mechanism for rotation of the spindle;
- a feed mechanism configured to move the cutting tool relative to the workpiece;
- and
- a movement controller configured to control the feed mechanism to bring the cutting tool into contact with the workpiece, while the spindle is rotating, to cause the cutting tool to cut the workpiece, wherein
- the rotation controller performing an acceleration control mode under which the rotation of the spindle is kept accelerated or a deceleration control mode under which the rotation of the spindle is kept decelerated, and
- the movement controller brings the cutting tool into contact with the workpiece after the rotation controller starts the rotation of the spindle, and separates the cutting tool from the workpiece while a rotation speed of the spindle is put under the acceleration control mode or deceleration control mode performed by the rotation controller.
A cutting method comprising:
- a rotation control step of controlling rotation of a spindle to which a cutting tool or workpiece is attached;
- and
- a machining step of bringing, while the spindle is rotating, the cutting tool into contact with the workpiece to cause the cutting tool to cut the workpiece, wherein
- the rotation control step includes performing an acceleration control mode under which the rotation of the spindle is kept accelerated or a deceleration control mode under which the rotation of the spindle is kept decelerated, and
- the machining step includes bringing the cutting tool into contact with the workpiece after start of the rotation of the spindle, and separating the cutting tool from the workpiece while a rotation speed of the spindle is put under the acceleration control mode or the deceleration control mode.
