Manufacturing and Mechanical Engineering Technology News

Dear Friends,

Even though it has been yet another pandemic year for us all, I want to share some good news. Despite all the challenges, we are still thriving here at Michigan Tech. We hope you are too.

This past week, 16 of our MET students graduated at Michigan Tech’s mid-year commencement, and most have accepted offers for engineering positions.

Our fall 2021 MET freshman class was again one of the larger groups in recent history at 24 students (same as last year). And our total enrollment for the MET degree program reached an all-time high: 172 students.

Several students enrolled in online courses to attain a graduate certificate in Manufacturing Engineering, which was initiated this year. The majority are MET alumni who work in manufacturing-related positions. In addition, we offer a new MS in Manufacturing Engineering and will soon begin accepting applicants for fall 2022.

Here in MMET, we continue to support the very popular new interdisciplinary MS degree in Mechatronics, offering five graduate courses including an innovative new course, MET5400: Key Factors of Holistic Safety Programs.

We look forward to a productive new year for 2022. We will continue to strive to prepare hands-on professionals that can apply industry 4.0 methodology. Please visit MMET to see our newly developed Mission, Vision, and Goals.

Be sure to reach out to me with any questions, and let me know if you have any news you would like to share. I always enjoy hearing from you. 

On behalf of all of us in the Department of Manufacturing and Mechanical Engineering and Technology, I wish you all a very happy and healthy holiday season.

New equipment in the Applied Fluid Power Lab, purchased with support from the Parker-Hannifin Foundation, was set up and operational by the start of classes in January 2021. In addition, grant funds from the National Fluid Power Association (NFPA) were used to develop a revised curriculum.

“Our new hydraulic equipment includes an additional set of basic and advanced modules for our existing double-sided trainer (donated by Parker in 2019), plus a new double-sided trainer, pump, basic and advanced modules to equip both sides,” Irwin explains. “We immediately put this new equipment to good use.”

In the MMET Applied Fluid Power course, students perform all the labs in the basic and advanced Parker manuals during a two-hour lab session. They use Automation Studio software for the simulation and analysis of hydraulic circuits.

One brand-new 3-credit graduate course, Advanced Hydraulics: Electrohydraulic Components and Systems was offered for the first time in fall 2021 for students pursuing an MS in Mechatronics. The curriculum for the course was developed this past spring and summer.

Mechatronics MS student Namratha Karanam was hired to set up and test the electrohydraulic system components–an Electrohydraulic Module and an Electrohydraulic Expansion Module, both donated by Parker in 2019. 

“In addition, Donald Engineering President, Mark Gauthier, generously donated a Pump Test Stand to supplement our course learning objectives,” says Irwin. “Their donation enables MMET faculty and students to evaluate flow rate and temperature change in and out of the cooling unit for the hydraulic pump.”

Michigan Tech’s production-style, polymeric additive manufacturing (AM) machines are all located in the MMET Machine Shop. MMET Department Chair John Irwin envisions a total of seven.

“In accordance with ASTM, all AM processes must fall into one of seven technology groups,” Irwin explains. “For optimum teaching and research, it’s become increasingly clear that we need seven types of printers, one for each different technology.”

“The first of the three machines in our MMET AM Lab is a Stratasys Fortus 400mc 3D prototyping machine with wash station, used for Fused Deposition Modeling (FDM). The second machine, for Vat Photopolymerisation—more commonly known as stereolithography—uses the 3D Systems Figure 4 Standalone Industrial 3D Printer. Finally, Material Jetting is done using the MJP 3600 with the PRO JET Finisher.”

Both undergraduate and graduate students stand to benefit from added equipment, says Irwin. “The MMET Machine Shop already serves as an important campus resource, serving both the MMET department and numerous other departments on campus.”

“Several undergraduate MMET labs are held in the Machine Shop,” notes Irwin. “A number of undergraduate Enterprise teams use the facility, as well.”

In addition, MMET graduate students use the Machine Shop as a place of learning. “Our Manufacturing Engineering MS degree course, MFGE 5300, covers the seven AM processes, how they work to produce a part, and how to design a part for the additive process,” says Irwin. “A second course, MFGE 5400, is a lab-based class in which students will bring their newly acquired knowledge from MFGE 5300 and apply it to designing and producing parts on each type of technology.”

A great deal of research goes on in the Machine Shop, too. “Graduate research projects are produced in this space on a daily basis for many disciplines across campus,” says Irwin. “Access to the best technology ensures the best research results. It also saves time, and in many cases, money, to the researcher—meaning they will be able to do more with their budget.” 

Fortunately, the MMET AM Lab is ready for growth. MMET Master Machinist Scott Meneguzzo and Operations/Facilities Supervisor Nicholas Hendrickson staff the Machine Shop full-time, along with help as needed from temporary employees. 

“Nicholas has operated the polymeric AM facility since 2013,” notes Irwin. “He has developed a billing structure to account for time and materials for AM projects, and recently completed training in order to operate and maintain Michigan Tech’s new Direct Metal Printer.” Hendrickson is also pursuing a PhD in Mechanical Engineering with a research focus in AM.

Last, but not least, printer material for AM is a critical need. “Each of the seven AM printing technologies is capable of printing a range of different material types. We need to have all these materials on hand,” says Irwin. “We also need example parts—produced from each material from each machine—so that a researcher can hold in their hand, feel and see each option in order to select the best printer and material for their project.”

“For the very same reasons, example parts are also important for educating students,” says Irwin. 

Michigan Tech Opens New Metal AM Facility

Adjacent to the Machine Shop, room 117 houses Michigan Tech’s new 3D Systems Direct Metal Printer (DMP), and the Flex 350 Production Printer. “This type of AM is for the manufacturing of high-precision metal parts with the 3D systems approved powders,” says Irwin. “This unit has a resolution of five microns and can process 11 unique metals, including bio-grade titanium (for biomedical applications), cobalt and chromium, several types of stainless steel, and more. “It’s available for research and development using custom powders, too.”
