Abstract

A method, non-transitory computer-readable medium, and controller for manufacturing a predetermined object. The method includes machining a plurality of separate components of a work piece based on a final geometry of the predetermined object. The plurality of separate components is selected based on the final geometry of the predetermined object. A first material is added to the work piece such that a first single continuous surface is formed over, or together with, the machined surfaces of the plurality of separate components which is selected based on the final geometry of the predetermined object.

First claim

What is claimed is:

1. A method for manufacturing a predetermined object, the method comprising:
machining a work piece, which is formed by a plurality of separate components, to remove excess material from the work piece based on a final geometry of the predetermined object to be manufactured from the work piece, the plurality of separate components being selected based on the final geometry of the predetermined object and arranged to approximate the final geometry of the predetermined object; and
adding a first material to the machined work piece using a laser beam such that a first single continuous surface is formed over, or together with, the machined surfaces of the plurality of separate components which is selected based on the final geometry of the predetermined object, the first material being a metal powder, wherein
each of the plurality of separate components has ends that are formed on parallel end planes and sides that are formed on side planes that are perpendicular to the end planes of the respective separate component.

2. The method according to claim 1 , further comprising:
machining the first single continuous surface to form a finished continuous surface.

3. The method according to claim 1 , further comprising:
securing the plurality of separate components of the work piece to a base before the plurality of separate components is machined.

4. The method according to claim 1 , further comprising:
determining the final geometry of the predetermined object; and
selecting the plurality of separate components based on the determined final geometry of the predetermined object.

5. The method according to claim 1 , wherein
the plurality of separate components includes blocks of different sizes, and
the blocks of different sizes are arranged to approximate the final geometry of the predetermined object.

6. The method according to claim 1 , wherein the steps of machining and adding are performed in a single additive and milling hybrid machining center.

7. The method according to claim 1 , further comprising:
after the plurality of separate components of the work piece is machined,
adding a separate component to the work piece, and
machining the separate component.

8. A non-transitory computer-readable medium storing instructions which when executed by a computer, cause at least one machining center to perform a method for manufacturing a predetermined object, the method comprising:
machining a work piece, which is formed by a plurality of separate components, to remove excess material from the work piece based on a final geometry of the predetermined object to be manufactured from the work piece, the plurality of separate components being selected based on the final geometry of the predetermined object and arranged to approximate the final geometry of the predetermined object; and
adding a first material to the machined work piece using a laser beam such that a first single continuous surface is formed over, or together with, the machined surfaces of the plurality of separate components which is selected based on the final geometry of the predetermined object, the first material being a metal powder, wherein
each of the plurality of separate components has ends that are formed on parallel end planes and sides that are formed on side planes that are perpendicular to the end planes of the respective separate component.

9. The non-transitory computer-readable medium according to claim 8 , the method further comprising:
machining the first single continuous surface to form a finished continuous surface.

10. The non-transitory computer-readable medium according to claim 8 , further comprising:
securing the plurality of separate components of the work piece to a base before the plurality of separate components machined.

11. The non-transitory computer-readable medium according to claim 8 , further comprising:
determining the final geometry of the predetermined object; and
selecting the plurality of separate components based on the determined final geometry of the predetermined object.

12. The non-transitory computer-readable medium according to claim 8 , Wherein
the plurality of separate components includes blocks of different sizes, and
the blocks of different sizes are arranged to approximate the final geometry of the predetermined object.

13. The non-transitory computer-readable medium according to claim 8 , wherein the steps of machining and adding are performed in a single additive and milling hybrid machining center.

14. The non-transitory computer-readable medium according to claim 8 , further comprising:
after the plurality of separate components of the work piece is machined,
adding a separate component to the work piece, and
machining the separate component.

15. A controller for manufacturing a predetermined object, the controller comprising:
circuitry configured to
cause a material removal tool to machine a work piece, which is formed by a plurality of separate components, to remove excess material from the work piece based on a final geometry of the predetermined object to be manufactured from the work piece, the plurality of separate components being selected based on the final geometry of the predetermined object and arranged to approximate the final geometry of the predetermined object; and

cause a material deposition tool to add a first material to the machined work piece using a laser beam such that a first single continuous surface is formed over, or together with, the machined surfaces of the plurality of separate components which is selected based on the final geometry of the predetermined object, the first material being a metal powder, wherein
each of the plurality of separate components has ends that are formed on parallel end planes and sides that are formed on side planes that are perpendicular to the end planes of the respective separate component.

16. The controller according to claim 15 , wherein the circuitry is further configured to:
cause a finishing tool to machine the first single continuous surface to form a finished continuous suffice.

17. The controller according to claim 15 , wherein the circuitry is further configured to:
cause a machining center, which includes the material removal tool, to secure the plurality of separate components of the work piece to a base before the plurality of separate components is machined.

18. The controller according to claim 15 , wherein the circuitry is further configured to:
determine the final geometry of the predetermined object; and
select the plurality of separate components based on the determined final geometry of the predetermined object.

19. The controller according to claim 15 , wherein
the plurality of separate components include blocks of different sizes, and
the blocks of different sizes are arranged to approximate the final geometry of the predetermined object.

20. The controller according to claim 15 , wherein the circuitry is further configured to:
after the plurality of separate components of the work piece is machined,
cause the machining center to add a separate component to the work piece, and
