Setting up a New ETM Lab

This last summer I had the great pleasure of working in the Engineering Technology and Management labs under Ron Porter. It was a wonderful experience that allowed me to see the laboratories within Stocker Center, the main building of the Russ College, with a whole new level of appreciation.

Primarily, the job entailed maintenance and cleanup of the existing labs. I still remember the first project we had was blowing out and cleaning up the immense amount of sawdust that had accumulated in lab 009. This is the woodworking lab for ETM, and I was truly not prepared for how much sawdust I experienced in that first week and a half.

As the weeks went on through the summer, we also were tasked with some jobs needed to prepare the road for the new ETM capstone lab. Some of the back rooms were just a treasure of really interesting old projects and equipment. It surprised me to find some of the processes and equipment have remained relatively unchanged after so many years. Just as interesting were the discoveries so obsolete that we had trouble even figuring out what they were.

I find myself much more aware in the lab sessions of my classes. When work is finished I am so much more motivated to make sure not only my area is cleaned, but the whole lab that was being used. Largely, it was because I was able to see behind the curtain and witness the amount of work put into our wonderful university. At the end of the day, it was a very eye-opening experience that left me much more invested in my classes and Ohio University as a whole.

Aluminum Castings

Ever since I took Metal Fabrication and Casting (ETM 2180) my sophomore year, I have been interested in castings. In the class, we were simply learning about the process. Now in my senior year, I’m delving deeper into the process.

One of the projects I have recently been working on is developing a casted aluminum OHIO badge using the sand casting process. My hopes behind this is to use the castings in my senior production run (capstone).

Casting

One thing that makes my development process different from traditional methods is that I have been developing and testing 3D printed patterns and runners which are traditionally machined or carved out. I started out with designing the badge using SolidWorks (a 3D drafting software). The part was then converted into a .STL file which could be read by the 3D printers owned by the ETM department.

Casting

Once the parts were printed, they were glued to the pattern board where sand could be packed around them. After the board is removed, a cavity is left for the molten aluminum to fill. As you can see, my first couple of patterns did not allow the sand to take.

Casting

After some massaging in the interior edges (larger fillets), larger draft angles and additional post print finishing I was able to create a workable pattern that was casted as seen in the picture at the top.

Now after creating a successful prototype and proving the concept, I have developed a (hopefully) ideal casting pattern that can be used in my capstone project next semester.

Geotechnical Engineering Lab

One of my favorite things about being a junior is that I’m finally getting out of my general education classes and getting into my major-specific ones. For instance, this semester I’m taking Geotechnical Engineering, a staple for all CE students. Along with the lecture, this class comes with a lab requirement. I love lab requirements. Especially ones that let me just play with dirt for an hour!

In Soils lab, we test the various properties of different soils using the tried-and-true methods we talk about in lecture. It’s the perfect way to help remember the differences between procedures that tend to become indistinguishable after class lets out.

Geotechnical Engineering Lab

The best part about this class (other than getting to squish mud between my fingers every Wednesday afternoon) is that it’s so easy to see the applications of this work to real life. The things we do in lab are the things real geotechnical engineers do every day. The Proctor tests, the Atterberg limit calculations…It’s not like our professors are dumbing down complex concepts and giving us experiments that don’t apply to anything. They’re taking real life work and letting us have that hands-on experience that all engineers adore. It makes me feel like I’m working towards something real!
