Mechanical Testing Apparatus
One of the tests for AOI required a custom test stand that could fit several components of varying sizes, without disrupting the optical set-up. Additionally, the test fixture would have to allow for optical inspection at varying heights, accounting for system calibration and accuracy between depth of field.
PLANNING
The first task was to determine how the camera would be mounted using existing OTS brackets and creating a vise that could accommodate the individual components for testing, allowing them to be replaced with speed and ease.
​
Originally, the camera was to be moved up and down to different heights for testing in order to maintain calibration at the varying fields of depth. For the vise, I took inspiration from another test being performed in our office that utilized springs to clamp an object in place.
MODIFICATIONS
After attempting to move the camera between tests, I determined that there was too much variance in results. The fixture design was modified to allow for movement of the vise rather than the camera and the program was updated accordingly.
​
After taking measurements of all of the parts, I was able to establish dimensions for the vise. I then performed basic force calculations to determine the necessary spring loads to keep the parts in place, which informed decisions for part selection.
FINAL
I created formal drawings with GD&T for the custom vise, along with other parts for testing, and had production-grade prototypes made overseas. After assembling all of the components, I was able to begin testing and data collection.
​
Due to time constraints, I was unable to finish all of the testing, but successfully proved the functionality of the program. I provided the team in Belarus with formal testing procedures.
