The second portion has at least one of a second surface configured to be recessed from a second portion of the part or a hollow portion.
Claims17
A method of creating a milling fixture, the method comprising:
- manufacturing a first surface of a tool, such that the first surface comprises a first perimeter and a shape formed complementary to a first portion of a part for a milling operation on the part when the part is located within the milling fixture;
- and
- manufacturing a second surface of the tool, such that the second surface comprises a second perimeter that lies within the first perimeter and recesses away from the first surface and from a second portion of the part with the first portion of the part contacting the first surface of the tool and the second portion of the part is facing and not contacting the second surface of the tool,
- wherein manufacturing the first surface and manufacturing the second surface comprises laying up a composite material and
- wherein the first surface of the tool comprises a number of through-holes for performing the milling operation on a side of the part facing and contacting the first surface of the milling fixture.

A method of performing a milling operation, the method comprising:
- placing a part onto a tool such that a first portion of the part contacts a first surface of the tool and a second portion of the part remains recessed from a second portion of the tool, such that the first surface comprises a first perimeter and a shape complementary to the first portion of the part, and the second portion of the tool comprises a second perimeter that lies within the first perimeter and a second surface configured to be recessed from and not contacting the second portion of the part when the part is located within the tool;
- holding the first portion of the part against the first surface of the tool;
- performing a number of milling operations on the part;
- and
- performing the number of milling operations on a side of the part facing the tool.
