I have been working on creating some of the pieces in the Titans of CNC course to develop a deeper understanding of CAM. Milling has a steep learning curve. I started with watching videos on how to use CAM. I then just started to mill. I found that when I actually started milling I was learning a lot more than just going over and over my CAM and set up. To actually see the tool path cutting in real time, I was able to get a deeper understanding of how everything worked. As my hours on Tulane's CNC Mill added up, I learned that understanding how your machine works, and the limits that you can go has been an essential thing in becoming a better machinist. On this machine, I know what feeds and speeds work best for the 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 out of it.

I worked closely with one of the lab members in The Ferris Lab, Bolivar Aponte, on this project. Bolivar needed to make something to hold the spectrometry probe in a way that when taking measurements of flowers, the probe and holder would not crush the pedals. The original set up of probe and holder was a slab of aluminum sitting on top of the flower with a small hole to hold the probe. We came up with a way that would reduce the amount of surface area on top of the flowers by angling the larger holder by 45 degrees and then making a cylindrical holder for the probe so that there is only a small surface area sitting on the flower. We needed to make this cylindrical holder so that there is no light penetrating to the measurement area. the probe itself is a cylinder with a small hole at the end where light comes out to take measurements. This set up we created will not only preserve the flowers better, but also make it easier to select the sample area.

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.

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.

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.
