For this project, I worked closely with Bolivar Aponte, one of The Ferris Lab members. Bolivar needed to make something to hold a spectrometry probe in a way that, when taking measurements of flowers, would not crush the petals. The original setup of the probe and holder was a slab of aluminum sitting on top of the flower, with a small hole to hold the probe. The probe itself is a cylinder with a small hole at the end where light comes out to take measurements. However, this setup crushed the flower, and made it difficult to position the probe. They also needed a design for the cylindrical holder that would not allow light to penetrate the measurement area. We came up with the solution of angling the larger holder by 45 degrees and creating a cylindrical holder for the probe, minimizing the surface area that makes contact with the flower. This setup not only preserves the flowers better, but also makes it easier to select the sample area.

Projects

CNC Mill

I have been working on creating some of the pieces in the Titans of CNC course to develop a deeper understanding of CAM. When I first started milling, I quickly learned how steep of a learning curve it is. After countless hours of watching videos on how to use CAM, reading the CNC Mill instruction manual, and lots of trial and error, I finally understand the inner workings of this machine and have realized how crucial this understanding is to becoming a good machinist. Through this process I now know what feeds and speeds work best for different tools, the optimal depths of cuts, adaptive clearing methods for pockets and contours, and most importantly, how hard I can push the machine to get the best results.

Below are all the revisions I went through to mill my first piece.

Below are the final versions of the first and second piece I milled from the Titans of CNC course.

CNC MILL Repair

I identified, rewired and fixed Tulane Makerspaces' CNC Mill. A few wires had not been secured in the machine because their clamps were broken. The wires pictured below are after I found them.

The Rubtsov Group (Optics Lab)

This lab came to me because they needed a new part for their labs spectrometer to hold a prism accurately. A few graduate students tried to make this part on a manual mill, but they were not getting the tolerances needed. I created the CAM and milled their part, which hit the tolerances.

In the lab

Below is a picture of the piece I made for the labs spectrometer in action. In the picture you can see the NeHe beam on the surface of the mirrors and on the prism that is being held by the piece I milled. The prism is not clean for alignment purposes.

The Ferris Lab (Ecology Lab)

For this project, I worked closely with Bolivar Aponte, one of The Ferris Lab members. Bolivar needed to make something to hold a spectrometry probe in a way that, when taking measurements of flowers, would not crush the petals. The original setup of the probe and holder was a slab of aluminum sitting on top of the flower with a small hole to hold the probe. The probe itself is a cylinder with a small hole at the end where light comes out to take measurements. However, this setup crushed the flower, and made it difficult to position the probe. They also needed a design for the cylindrical holder that would not allow light to penetrate the measurement area. We came up with the solution of angling the larger holder by 45 degrees and creating a cylindrical holder for the probe, minimizing the surface area that makes contact with the flower. This setup not only preserves the flowers better, but also makes it easier to select the sample area.

Water Jet

I worked on a project to cut this 1 inch thick, cold rolled slab of steel, into a new base to hold a vice. The entire operation took around 45 minutes. The garnet container needed to be refilled over 10 times and I was constantly checking the orientation of the the water jet cutter. In setting up the program, I had to take into account the kerf of the water as the holes and size of the base needed to run true to the design. I ran a very slow cut for this operation to ensure the the deflection of the water, as it first goes through the steel, does not curve too much through the cut.

Truss Project

I made a Pratt Truss. I designed each component and assembled the truss, connecting everything with screws, washers, and nuts.

Casting

I modeled and 3D printed a shape with large draft angles to go through the process of forming the mold and pouring the pewter. I then 3D printed a tiki head to do another casting with the rest of the pewter I had.
