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 improve this flow.
The purpose of this project was to develop a computer
imaging system that would aid in reliably evaluating these
experiments. The completed system consisted of a computer,
a frame grabber, video equipment and operating software.
Videotapes made of the fluid flow in the mold during the
pouring process were replayed into the computer and
evaluated. Custom software reduced the collected data to a
representative evaluation number.
Results show that the computer evaluations are reliable
and reproducible, but applications are limited because of
the cost, speed and power of available computer systems. / Graduation date: 1994
