Problems solved by technology

In these instances, the end portion of each stock rod fed into the mandrel is not deposited, resulting in waste
Therefore, in view of the above, there are challenges in the AFSD manufacturing process using raw material rods, such as increasing the deposition rate and improving the quality of the deposited material

Embodiment Construction

[0020] In view of the considerations discussed above, systems, methods, and apparatus are provided that involve loading feedstock rods for deposition in additive friction stir deposition (AFSD) manufacturing. Briefly, a plurality of stock bars are held in the receptacle of the AFSD machine, one of which is moved from a staging position by a staging mechanism into axial alignment with the mandrel of the AFSD machine. Multiple stock bars are held in the container by various structures and / or mechanisms, such as coil springs, chains and gear assemblies. The preparation mechanism may take different forms, including in the form of actuators (eg, motors), preparation springs, and rods.

[0021] The use of a container to hold and prepare a plurality of raw material rods enables each rod to be fed into the mandrel and deposited substantially continuously. As such, such a vessel enables the AFSD machine to be operated with an increased average deposition rate and with reduced or no op...

Abstract

A method for loading feedstock bars into an additive friction stir deposition machine (AFSD) is described. The method comprises containing a plurality of feedstock bars in a container disposed adjacent to a spindle of the additive friction stir deposition machine. The method further comprises moving one feedstock bar of the plurality of feedstock bars into axial alignment with the spindle of the additive friction stir deposition machine.

Description

technical field [0001] The present invention relates to additive manufacturing, and more particularly, to an additive friction stir deposition (AFSD) machine. Background technique [0002] In additive manufacturing, materials are typically deposited layer by layer to form a three-dimensional part. Additive manufacturing is popular for its ability to form parts with complex geometries using a variety of materials, including ceramics, glass, thermoplastics, and metal powders. [0003] Additive manufacturing involves different techniques for depositing materials in different ways. For example, directed energy deposition and material extrusion additive manufacturing involve the deposition of molten material. Other techniques sinter powder materials to build layers, such as certain types of powder bed fusion. Yet other additive manufacturing techniques are solid-state. One such technique is known as additive friction stir deposition (AFSD). In AFSD, additive materials are de...
