Abstract
Disclosed is a milling head for shaping a shoe support for an article of foot wear. The disclosed milling head includes abrasive surfaces that are configured to allow for the shaping of an unfinished block of support material on all of the top, side and medial arch area of the perimeter surfaces without removing the block of support material from a support such as a vacuum vise, and without the need to interchange milling heads. The disclosed milling head has a semi-spherical milling surface for milling a top surface of the shoe support and two conical milling surfaces for milling a perimeter surface and a medial arch area of the perimeter surface of the shoe support, respectively. The disclosed milling head saves costs of labor and time when shaping the block of support material.
Claims30
A milling head having a plurality of milling surfaces for forming a shoe support from an unfinished block of support material, the milling head comprising:
- at least a first angled undercutting surface;
- and
- a curved surface,
- wherein each surface is provided with a cutting surface,
- wherein the at least first angled undercutting surface is configured to perform milling a milling operation on a perimeter surface of the unfinished block of support material, and
- wherein the curved surface is configured to perform milling on a top surface of the unfinished block of support material.
A milling head having a plurality of milling surfaces for forming a shoe support from an unfinished block of support material, the milling head comprising:
- an attachment end;
- a semi-spherical milling surface for shaping a top surface of the unfinished block of shoe support material;
- at least a first conical milling surface for shaping a perimeter surface of the unfinished block of shoe support material;
- and
- at least a second conical milling surface for shaping a medial arch area of the perimeter surface of the unfinished block of shoe support material,
- wherein the semi-spherical milling surface is disposed distal to the attachment end,
- wherein the at least first and at least second conical milling surfaces are disposed between the attachment end and the semi-spherical milling surface, and
- wherein each of the semi-spherical milling surface, the at least first conical milling surface and at least second conical milling surface is coated with an abrasive.
A method of forming a shoe support from an unfinished block of support material comprising:
- providing a milling head comprising:
- at least a first angled undercutting surface;
- at least a second angled undercutting surface;
- and
- a curved surface,
- wherein each surface has a cutting surface,
- placing an unfinished block of shoe support material in a position on a support,
- wherein the support firmly holds the unfinished block of shoe support material in place and provides for exposing the perimeter and medial arch surfaces to the action of the milling head,
- wherein the unfinished block of shoe support material has a top surface, a perimeter surface and a medial arch area of the perimeter surface;
- shaping the top surface with the curved surface;
- undercutting the perimeter surface with the at least first angled undercutting surface, and
- undercutting the medial arch area of the perimeter surface with the at east second angled undercutting surface,
- wherein the shaping of the top surface, the undercutting of the perimeter surface and the undercutting of the medial arch area of the perimeter surface is performed by moving the milling head in any combination of an “X” direction, a “Y” direction and a “Z” direction, and
- wherein the undercutting of the perimeter surface and the undercutting of the medial arch area of the perimeter surface are performed without removing the shoe support material from position on the support.
