Using Electronic Faculty Course Portfolios To Showcase Classroom Practices And Student Learning, Paul Savory, Amy M. Goodburn Dec 2009

Using Electronic Faculty Course Portfolios To Showcase Classroom Practices And Student Learning, Paul Savory, Amy M. Goodburn

Department of Industrial and Management Systems Engineering: Faculty Publications

Faculty course portfolios are a valuable medium for documenting and making visible the serious intellectual work of teaching. Developing a faculty course portfolio follows the same process one uses to explore a research question. Faculty members inquire, analyze, and document their teaching practices and the resulting student learning and then make the results accessible for use, review, and assessment by one’s peers. In this article, we introduce four types of electronic course portfolios that sponsor different forms of inquiry into student learning. We highlight the major components of each type, offer advice in developing them, and share examples of each. …

Teaming Multi-Level Classes On Industry Projects, Lizabeth Schlemer, Jose Macedo Mar 2009

Teaming Multi-Level Classes On Industry Projects, Lizabeth Schlemer, Jose Macedo

Industrial and Manufacturing Engineering

For the past few years we experimented with teaming students from a sophomore-level class and a senior-level class to work on industry projects. The classes are “work design” and “facilities design.” Projects are selected to require the application of knowledge from both disciplines. In addition, the projects are selected from small local companies. The intent of this paper is to describe the benefits and difficulties associated with this methodology. While specific classes in this experience are typical of an industrial engineering curriculum, the lessons learned and benefits could translate to other disciplines.


Optimization Of Engineering Tolerance Design Using Revised Loss Functions, Jeh-Nan Pan, Jianbiao Pan Feb 2009

Optimization Of Engineering Tolerance Design Using Revised Loss Functions, Jeh-Nan Pan, Jianbiao Pan

Industrial and Manufacturing Engineering

Engineering tolerance design plays an important role in modern manufacturing. Both symmetric and asymmetric tolerances are common in many manufacturing processes. Recently, various revised loss functions have been proposed for overcoming the drawbacks of Taguchi's loss function. In this article, Kapur's economic tolerance design model is modified and the economic specification limits for both symmetric and asymmetric losses are established. Three different loss functions are compared in the optimal symmetric and asymmetric tolerance design: a revised Taguchi quadratic loss function, an inverted normal loss function and a revised inverted normal loss function. The relationships among the three loss functions and …

Finding And Optimising The Key Factors For The Multiple-Response Manufacturing Process, Jeh-Nan Pan, Jianbiao Pan, Chun-Yi Lee Jan 2009

Finding And Optimising The Key Factors For The Multiple-Response Manufacturing Process, Jeh-Nan Pan, Jianbiao Pan, Chun-Yi Lee

Industrial and Manufacturing Engineering

With the advent of modern technology, manufacturing processes became so sophisticated that a single quality characteristic cannot reflect the true product quality. Thus, it is essential to perform the key factor analysis for the manufacturing process with multiple-input (factors) and multiple-output (responses). In this paper, an integrated approach of using the desirability function in conjunction with the Mahalanobis-Taguchi-Gram Schmit (MTGS) system is proposed in order to find and optimise the key factors for a multiple-response manufacturing process. The aim of using the MTGS method is to standardise and orthogonalise the multiple responses so that the Mahalanobis distance for each run …

Automated Fixture Design For A Rapid Machining Process, Wutthigrai Boonsuk, Matthew C. Frank Jan 2009

Automated Fixture Design For A Rapid Machining Process, Wutthigrai Boonsuk, Matthew C. Frank

Faculty Research & Creative Activity

Rapid prototyping techniques for CNC machining have been developed in an effort to produce functional prototypes in appropriate materials. One of the major challenges for rapid machining is to develop an automatic fixturing system for securing the part during the machining process. The method proposed in this paper is the use of sacrificial fixturing, similar to the support structures in existing rapid processes like Stereolithography. During the machining process, sacrificial supports emerge incrementally and, at the end of the process, are the only entities connecting the part to the stock material. This paper presents methodologies for the design of sacrificial …
