Abstract
A machining apparatus for a curved plate includes a holder that holds a main surface of a curved plate having curved surfaces on both main surfaces; a machining device that machines an outer circumference of the curved plate held by the holder; a movable frame that retains the machining device; a driver that moves the movable frame to move a machining point of the curved plate held by the holder; a controller that controls the driver; and a guide that guides the movable frame along the outer circumference of the curved plate held by the holder.
Claims29
A machining apparatus for a curved plate, comprising:
- a holder that holds a main surface of a curved plate having curved surfaces;
- a machining device that machines an outer circumference of the curved plate held by the holder;
- a movable frame retaining the machining device with respect to the outer circumference of the curved plate held by the holder;
- a driver that moves the movable frame such that the machining device retained by the movable frame moves a machining point of the curved plate held by the holder;
- a controller comprising circuitry configured to control the driver such that the driver moves the movable frame along the outer circumference of the curved plate held by the holder;
- and
- a guide that guides the movable frame along the outer circumference of the curved plate held by the holder such that the guide restricts a rotational motion of the movable frame pressed against the guide with respect to a moving direction of the movable frame.

- a holder that holds a main surface of a curved plate having curved surfaces;
- a machining device that machines an outer circumference of the curved plate held by the holder;
- a movable frame retaining the machining device with respect to the outer circumference of the curved plate held by the holder;
- a driver that moves the movable frame such that the machining device retained by the movable frame moves a machining point of the curved plate held by the holder;
- and
- a controller comprising circuitry configured to control the driver such that the driver moves the movable frame along the outer circumference of the curved plate held by the holder,
- wherein the holder has a curved surface and a guide formed along a curvature of the curved surface of the holder such that the guide makes contact with the movable frame and guides the movable frame along the outer circumference of the curved plate held by the holder.
A method of manufacturing a curved plate with a machined outer circumference, comprising:
- holding a main surface of a curved plate having curved surfaces by a holder;
- machining, by a machining device, an outer circumference of the curved plate held by the holder;
- and
- guiding, when a movable frame retaining the machining device is moved in the machining, the movable frame along the outer circumference of the curved plate held by the holder, by using a guide,
- wherein the machining includes moving the movable frame by an industrial robot.
A method of manufacturing a curved plate with a machined outer circumference, comprising:
- holding a main surface of a curved plate having curved surfaces by a holder having a curved surface;
- machining an outer circumference of the curved plate, held by the holder, by a machining device;
- and
- guiding, when a movable frame retaining the machining device is moved in the machining, the movable frame along the outer circumference of the curved plate held by the holder, by using a guide formed in the holder along a curvature of the curved surface of the holder.
