Abstract
A method of forming a metal workpiece is disclosed herein. The method includes applying an electrical current through a feedstock material, applying a vertical axis force to the feedstock material; applying a rotational force to the feedstock material, and producing a metallic component from the feedstock material based on the electric current, the vertical axis force, and the rotational force.
Claims17
A method for forming a metal workpiece, comprising:
- applying an electrical current to a feedstock material;
- applying a vertical axial force to a first end of the feedstock material, wherein the axial force is provided via a press mechanism;
- applying a rotational force to the feedstock material;
- and
- producing a metallic component from a second end of the feedstock material based on the electrical current, the vertical axial force, and the rotational force,
- wherein a first end of an electrical current circuit supplying the electrical current is applied to the first end of the feedstock material and a second end of the electrical current circuit is applied to a substrate.
3 more elements
A system, comprising:
- an electric current source;
- a force mechanism;
- a rotating tool;
- a controller;
- and
- a tangible, non-transitory memory configured to communicate with the controller, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising:
- commanding the electric current source to apply an electrical current to a feedstock material;
- commanding the force mechanism to apply a vertical axial force to a first end of the feedstock material, wherein the axial force is provided via a press mechanism;
- commanding the rotating tool to apply a rotational force to the feedstock material;
- and
- producing a metallic component from a second end of the feedstock material based on the electrical current, the vertical axial force, and the rotational force,
- wherein a first end of an electrical current circuit supplying the electrical current from the electric current source is applied to the first end of the feedstock material and a second end of the electrical current circuit is applied to a substrate on which the metallic component is produced.
9 more elements
A method of forming a metal workpiece, comprising:
- receiving a feedstock material comprising a first material;
- applying an electrical current to the feedstock material to heat the feedstock material to a first temperature;
- applying a vertical axial force to a first end of the feedstock material, wherein the axial force is provided via a press mechanism;
- applying a rotational force to the feedstock material, wherein an application of the vertical axial force and the rotational force causes a second end of the feedstock material to heat to a second temperature, wherein the second temperature is higher than the first temperature;
- and
- producing a metallic component from the second end the feedstock material,
- wherein a first end of an electrical current circuit supplying the electrical current from an electric current source is applied to the first end of the feedstock material and a second end of the electrical current circuit is applied to a substrate on which the metallic component is produced.
