Abstract
A method of manufacturing a part with a plurality of cut segments includes receiving a sheet of material with a machining apparatus and removing material during one or more first passes with the machining apparatus to form a plurality of segments in the sheet of material. The method also includes forming a tab by removing material during the one or more first passes with the machining apparatus for forming the segments, the tab connecting two segments within the sheet of material to each other and removing material with the machining apparatus to form joints on the segments.
Claims20
A method of manufacturing a part, the method comprising:
- forming a plurality of segments including a first segment and a second segment by removing material from a sheet of material with a machining apparatus,
- forming a first portion of a joint on a first side of the first segment and a second portion of the joint on a second side of the second segment, the first portion of the joint and the second portion of the joint being machined to an oversized form having dimensions that are larger than final dimensions;
- forming a first tab on a third side of the first segment and a second tab on a fourth side of the second segment;
- removing the first tab and the second tab and machining the first portion of the joint and the second portion of the joint to the final dimensions prior to removing the first tab and the second tab;
- forming a layer by attaching the first segment to the second segment such that the first portion of the joint receives the second portion of the joint.
A method of manufacturing a part, the method comprising:
- forming a plurality of segments including a first segment and a second segment by removing material from a sheet of material with a manufacturing apparatus,
- forming a first portion of a joint on a first side of the first segment and a second portion of the joint on a second side of the second segment, the first portion of the joint having a first shape and the second portion of the joint having a second shape, the first shape including a recess and a second shape including a protrusion, the joint being formed in multiple stages including:
- one or more first passes performed with the manufacturing apparatus, during which one or more tabs are formed while a first portion of the joint and a second portion of the joint are machined to an oversized dimensions that are larger than final dimensions;
- and
- one or more second passes with the machining apparatus, during which the one or more tabs are removed and the first joint portion of the joint and the second portion of the joint are machined to the final dimensions prior to removing the one or more tabs such that the recess of the first portion of the joint receives the protrusion of the second portion of the joint.
A method of manufacturing a part, the method comprising:
- forming a plurality of segments by removing material from a sheet of material during one or more first passes with a machining apparatus;
- forming a plurality of removable tabs on the plurality of segments using a tool, wherein forming at least one removable tab includes:
- raising the tool while the tool is positioned at a first angle with respect to a direction of movement of the tool;
- and
- lowering the tool while the tool is positioned at a second angle with respect to the direction of movement of the tool.
