Abstract
A machine tool includes a main spindle that rotates while holding a workpiece, a mover that moves a cutting tool including a linear cutting blade that cuts the workpiece, with respect to the workpiece in a moving direction including at least a Z-direction parallel or substantially parallel with the axis of the main spindle and a Y-direction perpendicular or substantially perpendicular to both the Z-direction and an X-direction determining the amount of cutting of the workpiece, a holder that holds the cutting tool in a state in which the direction of the linear cutting blade is inclined with respect to the Z-direction by a predetermined angle when seen from the X-direction, and an angle adjuster that changes the edge angle.
Claims7
A machine tool comprising:
- a main spindle that rotates while holding a workpiece;
- a mover that moves a cutting tool with respect to the workpiece in a moving direction including at least a Z-direction parallel or substantially parallel with an axis of the main spindle and a Y-direction perpendicular or substantially perpendicular to both the Z-direction and an X-direction, the X-direction being perpendicular or substantially perpendicular to the Z-direction and determining an amount of cutting in a radial direction of the workpiece, the cutting tool including a linear cutting blade that cuts the workpiece;
- a holder that holds the cutting tool in a state in which a direction of the linear cutting blade is parallel or substantially parallel with a YZ plane and is inclined with respect to the Z-direction by a predetermined angle when seen from the X-direction;
- and
- an angle adjuster that changes the predetermined angle;
- wherein
- the moving direction is a direction obtained by combining the Z-direction and the Y-direction.
A method for machining a workpiece rotating while being held by a main spindle, the method comprising:
- moving a cutting tool with respect to the workpiece in a moving direction including at least a Z-direction parallel or substantially parallel with an axis of the main spindle and a Y-direction perpendicular or substantially perpendicular to both the Z-direction and an X-direction, the X-direction being perpendicular or substantially perpendicular to the Z-direction and determining an amount of cutting in a radial direction of the workpiece, the cutting tool including a linear cutting blade that cuts the workpiece;
- holding the cutting tool in a state in which a direction of the linear cutting blade is parallel or substantially parallel with a YZ plane and is inclined with respect to the Z-direction by a predetermined angle when seen from the X-direction;
- and
- changing the predetermined angle;
- wherein
- the moving direction is a direction obtained by combining the Z-direction and the Y-direction.
