Playing an ace: Workforce Development & Training

Several years ago, amid concerns about the state of its machining technology and workforce, America pulled an ACE out of its sleeve.

Launched in 2020, America’s Cutting Edge (ACE) is a national program aimed at bolstering the U.S. machining industry. “ACE was born out of the understanding that machine tools and machining processes are critical to U.S. manufacturing in general and the Department of Defense (DoD) specifically,” noted Tony Schmitz, a professor at the University of Tennessee, Knoxville, (UT) and director of the Machine Tool Research Center at the university.

A key figure in the creation and current operation of ACE, Schmitz pointed out that the program has two primary components. One is research and development at the U.S. Department of Energy’s Manufacturing Demonstration Facility at Oak Ridge National Laboratory. The purpose of this R&D is to improve U.S. machine tools and machining processes.

The other component is an effort to address the worker shortage in the industry by educating young people and others about machining and jobs in the field. In this area, ACE benefits from the workforce-development experience of the Institute for Advanced Composites Manufacturing Innovation. IACMI manages the ACE workforce initiative through an agreement with the DoD’s Industrial Base Analysis and Sustainment (IBAS) program, which provides funding for the effort.

Machining Education

A professor with a career in machining technology, Schmitz took on the job of coming up with an educational approach that would serve as the foundation for ACE’s workforce-development effort. “My initial role was to develop curriculum and decide how we’d like to share that in order to reach a broad audience,” he said.

What eventually emerged was free online and in-person training in CNC machining and metrology. Introduced in December 2020, Schmitz’s online CNC machining training curriculum includes an introduction to machining, machining dynamics and machining costs, as well as CAM instruction. People from all 50 states have registered for ACE’s online machining instruction, according to IACMI.

The program’s online metrology training includes an introduction to manufacturing measurements and measurement uncertainty. Both the machining and metrology training can be accessed by registering at AmericasCuttingEdge.org. No prior training or experience is required to enroll in the programs.

Those who complete the online training are eligible for 32 hours of free in-person training at UT and other locations. In-person metrology training will be available for the first time this spring, according to Schmitz. Completed over five days, the in-person machining training includes component manufacturing with machine tools.

At UT, Schmitz and some of his students were the first in-person machining trainers. Today, however, their role is to train the trainers for the 29 ACE locations that have sprung up around the country. “It is a full-time job for us to train the trainers,” Schmitz said, adding that all trainer candidates must have prior CNC machining experience.

To facilitate the spread of ACE instruction around the country, IACMI has followed a hub-spoke model. ACE hubs have been established at seven sites in different areas. With the hubs in place, spokes are added to support them, explained IACMI’s Kim Harris, who has overseen implementation of the ACE training program. Established at places such as high schools, community colleges, colleges of applied technology and universities, spokes carry out the ACE mission, training students and working adults interested in learning about machining. IACMI provides the hubs and spokes with budgets for training and equipment and also monitors their activities to make sure that program objectives are being met.

ACE Hub

One of the ACE hubs is the Texas A&M Engineering Experiment Station (TEES), which seeks to support U.S. manufacturing with innovative approaches to technology and workforce development. “The state charters us with growing the industrial base in engineering in the state of Texas. So it seemed like a natural fit for us to get involved with ACE and help scale up that program,” noted John Peterson, senior project manager for manufacturing workforce initiatives at TEES.
