Investment casting has been an important form of metal casting
for many years, but little is understood about the fluid flows that
occur during mold filling. A key to quality castings is the
understanding and control of the fluid flows that are present when the
mold is filled with molten...
Significant reductions in the number of defects in parts
produced by investment casting can be obtained by improving
the flow of the molten metal during pouring. Studies have
been done at Oregon State University with simulated casting
techniques to determine optimal mold configurations.
Better mold layouts have been shown to...
In the past half century, industrial robots have developed a strong presence in manufacturing. They now commonly perform tasks such as materials handling, assembly, welding, and painting. Unfortunately robotic machining tasks have seen limited deployments. The majority of machining robots are designed for soft materials like wood or plastic and...
This paper documents the investigation into injection molding, or die casting, a bulk metallic glass (BMG). A BMG is an amorphous metal of a thickness greater than 25 μm, according to leading researchers in the field. This critical thickness differentiates a normal metallic glass from a "bulk" metallic glass. The...
