I have been working on creating some of the Titans of CNC pieces to develop a deep 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 actually milling I was learning a lot more. Actually seeing the tool path cutting in real time, I was able to get a deeper understanding of how everything worked. Understanding how your machine works has been an important thing that I have learned from all my time milling. I know what this mill can and cannot handle. I know what feeds and speeds work best for the different tools I use, and most importantly, I know how hard I can push the machine to get the best results out of it.

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.

During a Mill job I kept on getting a Z-Axis fault. I had never gotten an error like this and I had to start from scratch from how to approach this problem. I only knew that this fault happened during a milling operation. It was during an adaptive clearing of a pocket so there was a lot amount of chatter. I read through the owners manual but the wires in the mills electrical cabinet had been changed around so it did not match with the manual. The manual did say that some wires could become loose if there are enough vibrations. From that, I began going through the whole electrical cabinet, learning about what each of the components do. I located the area that had some relation to the axis motors. I found a set of wires that would fault the machine when I moved them around. They were quick disconnect clips, so I took off the old clips are then re-crimped new ones. I then went back to move them around and the machine continued to fault. I then realized that I was probably moving around other wires. I then went through the wires around that area. I then found the wires that were causing the issue. I was correct with my original assumption that the chatter from my mill operation was shaking the wires loose. The 3 wires that were coming out had broken clamps connecting them to the machine. I could not move the wires to another part of the machine without soldering longer wires onto them. Took fix this quickly I added some electrical tape around the wires to fit snug and then hot glued them in so that would not shake out.  
+
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.

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.

I worked closely with one of the lab members in The Ferris Lab, Bolivar Aponte, on this project. We needed to come up with a way to take spectrometry measurements on flowers that would preserve the flower as best we could. The original set up of this lab was having a slab of aluminum sit 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 surface by 45 degrees and then making a holder for the probe so that there is only a small sitting on the flower. This will not only preserve the flowers better, but also make it easier to select the sample area.

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.

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.

Casting is very useful for making things that have odd shapes. However, casting does have its restraints. One restraint is that there needs to be draft angles so that the model can come out without ruining the mold.

I then 3D printed a tiki head to do another casting with the rest of the pewter I had.
