1. A method of forming an article of footwear comprising:
cutting a first group of parts from a first area of a bulk material during a first cutting operation, the first group including a first part and a second part of the article of footwear, the first part and the second part being separate and distinct from each other and having different shapes, the first part and the second part cut along a common internal cutting line that defines a first edge of the first part and a second edge of the second part, the first part and the second part being cut using a same cutting die during the first cutting operation, wherein the entire common internal cutting line defines the first edge of the first part and the second edge of the second part; and cutting a second group of parts from a second area of the bulk material during a second cutting operation, the second group including a first part and a second part, the first part of the second group corresponding in shape to the first part of the first group, the second part of the second group corresponding in shape to the second part of the first group, the second group cut along a common external cutting line that defines a first boundary of the first group and a second boundary of the second group, wherein the first boundary has a first curvature, wherein the second boundary has a second curvature that is inverse to the first curvature, and wherein the first boundary and the second boundary are partially coextensive to nest the first group with the second group, wherein the common internal cutting line includes a first end and a second end, and wherein the first end intersects the common external cutting line, the second end intersects the common external cutting line, and both the first end and the second end are on a same side of the first group of parts. |
