Abstract
A hole drilling method includes a rotating step of attaching a workpiece to a rotary table to make the workpiece rotate in an opposite direction to the rotating direction of the rotary tool and a drilling step of making the rotary tool and the workpiece move relative to each other in a direction in which they approach each other so as to drill a hole. The hole drilling step comprises making a position of the rotary tool track the rotation of the workpiece while drilling the hole so that the rotary tool is arranged at a position for drilling a hole in the workpiece.
Claims6
A hole drilling method for making a rotary tool rotate while making the rotary tool and a workpiece move relative to each other so as to drill a hole, comprising:
- a rotating step of attaching the workpiece to a workpiece rotating device to make the workpiece rotate in an opposite direction to a rotating direction of the rotary tool;
- and
- a hole drilling step of making the rotary tool and the workpiece move relative to each other in a direction in which the rotary tool and the workpiece approach each other so as to drill a hole;
- wherein
- the hole drilling step comprises making a position of the rotary tool track rotation of the workpiece while drilling the hole so that the rotary tool is arranged at a position for drilling the hole in the workpiece.
A machine tool for rotating a rotary tool while making the rotary tool and a workpiece move relative to each other so as to drill a hole, comprising:
- a workpiece rotating device which makes the workpiece rotate about an axis of rotation parallel to an axis by which a rotary tool rotates;
- a movement device which changes a relative position of the rotary tool and the workpiece;
- and
- a control device which controls the movement device;
- wherein
- the control device controls a rotating direction of the rotary tool and a rotating direction of the workpiece to become opposite and controls the movement device so as to drill the hole while making a position of the rotary tool track rotation of the workpiece so that the rotary tool is arranged at a position for drilling the hole in the workpiece.
