AbstractThe Geometric Dimensioning and Tolerancing (GD&T) ASME Y14.5 standard 1 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.

In response to a need identified by the Society of Manufacturing Engineers' Education and Research Technical Community, a survey was conducted to assess the health of ABETaccredited manufacturing engineering technology programs in the spring of 2005 and 2007. In 2005, thirty-eight programs received the survey via email and twenty-two programs provided a response. Survey questions focused on enrollment issues, laboratories, regional manufacturing industrial base, graduate success, and student recruiting resources. Now, the survey has been updated and all programs currently listed on the ABET website have been contacted in early 2007. This paper will present the original results of the survey as well as results from the spring 2007 survey. Thus the paper helps establish overall national trends for, and, when possible, within manufacturing engineering technology programs. These results provide information regarding manufacturing engineering technology program health. Thus, inferences are drawn regarding the state of manufacturing engineering technology education across the nation. These programs are functioning within a complex environment-one that is a blend of both pessimism and opportunity. It is also worth noting that, within engineering education, there are more manufacturing engineering technology programs (baccalaureate) than there are manufacturing engineering programs. Thus, a large portion of the manufacturing-focused Bachelor of Science degrees granted within the US is from engineering technology programs.

Trian Georgeou, Arizona State University Trian Georgeou graduated from Arizona State University (ASU) in 2003 with a Bachelor of Science in Manufacturing Engineering Technology. He worked in industry as a Mechanical Engineer while attending graduate school, earning his Master of Science in Technology, concentration of Mechanical Engineering Technology in 2006. While in graduate school, Trian also taught as an adjunct faculty member in Chandler Gilbert Community College's Automated Manufacturing Systems program. Trian worked in the aftermarket automotive industry as an engineering and design consultant for two major companies. Currently, he is a Lecturer in the ASU Mechanical and Manufacturing Engineering Technology Department while remaining active in the aftermarket automotive industry.

be made with minimum effort in the future. On the instrumentation front, pressure transducers and a data-logger were fully integrated with the wind tunnel measurement system. Variable inputs were geometric design parameters related to the truck cab and the collection bin sections, wind speed, and yaw angle (cab orientation). Output was dynamic pressure from fifty-four test points in the truck. Statistical analysis of normalized data using Minitab ® included analysis of variance, linear regression analysis to establish significant input variables, and contour plots of the pressure fields generated in Excel ®. The main effects account for half of the measured response, there are interactions between some main effects, and other probable variables exist. Brief descriptions of the changes to the wind tunnel, design and fabrication of the truck models, factorial design, and the experimental process are given below. As mentioned above, the experimental study described in the present paper supported a M.S. Thesis work in the department. The investigation was comprehensive, rigorous and led to useful results and information that will be of immediate use to the industry at large. Additionally the tasks associated with the study such as the use of rapid prototyping equipment for making the test models will serve as the template for future such endeavors. Even though the redesigned tunnel was used to address the specific problem faced by the industry right now, the students gain valuable experience in solving practical problems of interest to present day industry as they work on a variety of applied projects using the tunnel.
