Eric Holloway currently serves as the Senior Director of Industry Research in the College of Engineering at Purdue University, where he focuses on industry research in the College of Engineering.

From 2007-2013, Eric served as the Managing Director and the Director of Instructional Laboratories in the School of Engineering Education at Purdue University. As Director, he was in charge of the building and implementation of the Ideas to Innovation (i2i) Laboratory, which opened in August 2008 and houses classrooms and laboratories used by the 2000 students in Purdue’s First-Year Engineering Program. He oversaw the daily operation of the i2i lab, and was responsible for the personnel, logistics, and technology used in the classroom and labs. Eric also helped build and directed the College of Engineering sponsored Artisan and Fabrication Lab (AFL), which houses a machine shop, carpentry shop, and a prototyping lab used by all students in the College of Engineering for project work. In 2009, he received a New Employee Staff Award of Excellence from the College of Engineering for his work in launching the i2i lab. Eric has served as the university representative on the Haas Technical Education Council, which is committed to developing manufacturing expertise at the high school, trade school, and university level. He received a BSEE from Purdue University in 1992. He has over 15 years of industrial experience, specializing in manufacturing and electronic controls, for which he holds 3 patents. Eric’s industrial experience includes positions at Toyota, Cummins, Woodward, and TRW Automotive. He is currently pursuing his PhD in Engineering Education from Purdue, with an expected graduation date of 2020.

Traditional engineering curricula place a premium on education related to design and analysis. Often, this leads to little or no formal education related to manufacturing processes. To become more effective designers and analysts, students must gain exposure to advanced manufacturing tools and processes. This paper explores how CAD/CAM technology is being used at a large Midwestern university’s Artisan and Fabrication Laboratory to facilitate experience with digital manufacturing techniques through hands-on learning opportunities. Specifically, it describes the development and implementation of an integrated CAD/CAM workflow that reduces the difficulty of learning complex digital fabrication tools so that students can more easily obtain manufacturing experience while building on their design knowledge. This workflow was built utilizing integrated CAD/CAM tools (CATIA v5 and Siemens NX), and features a custom user environment, tool and process catalogs, CNC machine simulation, and process validation. Further, this unique implementation deploys online learning modules, teaching assistant training, and consultations to further facilitate learning and familiarity with manufacturing processes. The result is a fully functional workflow that allows for engineering students to gain experience with digital manufacturing techniques using a project-based learning perspective.
