Dr. Dan Waldorf, Professor in Industrial and Manufacturing Engineering, joined the Cal Poly faculty in 1998 after two years in Chicago as a Quality/Manufacturing Engineer at ATF, Inc., a supplier of specialty cold-formed and machined components for automotive applications. At ATF he implemented process control technologies, taught and instituted quality control systems, and designed experiments in a traditional manufacturing environment. He received his Ph.D. in industrial engineering in 1996 from the University of Illinois at Urbana-Champaign, where, as a graduate student, he taught quality and applied statistics and researched machining models for monitoring and control. At Cal Poly, Dr. Waldorf has taught and developed courses in manufacturing process design, computer-aided manufacturing, tool engineering, quality engineering, and reliability. He has participated in numerous activities related to the improvement of teaching methods, teaching assessment, and curriculum design. He is currently the faculty advisor for Society of Manufacturing Engineers (SME). His research interests are in metal cutting process modeling, tool wear, cutting tool design, and engineering education.
Trian Georgeou is a Lecturer in the Industrial & Manufacturing Engineering (IME) department at California Polytechnic State University San Luis Obispo. Before joining Cal Poly in 2014, he spent eight years as a full-time faculty member teaching in the Mechanical & Manufacturing Engineering Technology programs as well as the General Engineering & Manufacturing Engineering programs at Arizona State University (ASU) Polytechnic. While at ASU he also worked as an engineering and manufacturing design consultant for two aftermarket automotive companies, and his own company which designed and manufactured parts for wakeboard/ski boats. Mr. Georgeou earned a Master of Science in Technology, concentration in Mechanical Engineering Technology in 2006. While attending graduate school, he taught as an adjunct faculty member in Chandler Gilbert Community College’s Automated Manufacturing Systems program. Before attending graduate school Trian worked for Hasport Performance as a manufacturing engineer where he designed and manufactured aftermarket motor mounts for import automobiles. He earned his Bachelor of Science degree in Manufacturing Engineering Technology in 2003 from ASU. Currently Trian teaches courses for the IME department in computer-aided-design (CAD), manual machining processes, fixture design, computer-aided-manufacturing (CAM) and computer-numerical-control (CNC) machining.
The Geometric Dimensioning and Tolerancing (GD&T) ASME Y14.5 standard for specifying engineering requirements on drawings and related documentation was initially accepted in 1994 and has been formally modified as recently as 2009. Despite many advantages for clarifying and simplifying design requirements as well as implications for reducing manufacturing costs and streamlining manufacturing activities, the various aspects of the standard have seen inconsistent adoption throughout the manufacturing industries across the US. A recent increase in employer expectations when hiring undergraduates at one institution has prompted an ambitious effort to increase student learning of GD&T standards and of the numerous practical ways to utilize it to achieve high quality, low cost manufacturing. The effort involves integrating different aspects of the standard across a broad spectrum of the curriculum for both an undergraduate major program in manufacturing engineering and for a manufacturing engineering concentration in a mechanical engineering program. Lecture content, assignments, lab exercises, and projects have been developed across eight different courses to increase understanding of GD&T from various perspectives such as documentation, mechanical design, design for assembly, design for manufacture, fixture design, machining, and inspection. Altogether, the content covers most of the key GD&T concepts and provides a consistent, coherent approach to graduating GD&T-savvy manufacturing and mechanical engineers. A comprehensive exam has been compiled to track student learning and to monitor the effectiveness of new efforts in this key area.
