Design And Manufacture

From time to time the Royal Society organizes meetings for the discussion of some new development in engineering and applied science. It seemed possible to the organizers of this meeting that it would be profitable to bring together workers in industry and in the universities to discuss some aspect of computer-aided design. As you will see we have chosen the application of computer aids to mechanical engineering design and manufacture. This restriction to mechanical engineering was deliberate, partly because the application of computer aids to mechanical engineering design is somewhat behind similar activities in electrical and civil engineering. Another reason is that the development of such applications has reached a particularly interesting stage, and it is now perhaps appropriate to review progress and to discuss the directions in which future research should proceed. Although some examples of computer-aided design in mechanical engineering can be found from the earliest days of computing, the development really started in the late fifties with early experiments in the use of graphic displays and with the introduction of multi-access computing. Some may date the beginning of the developments which we are going to discuss today, from the work at M. I. T. on automated programmed drawing started in 1958. This has led to a concentration of effort on graphics and computer-aided drafting. Much research has been done on the mathematical description of curves, surfaces and volumes in a form suitable for engineering design. Work has been done on the automatic dimensioning of drawings, hidden line removal, the prob­lems of lofting, etc.

The Impact

AbstractThis paper presents a preliminary comparison between the role of computer-aided design (CAD) and sketching in engineering through a case study of a senior design project and interviews with industry and academia. The design team consisted of four senior level mechanical engineering students each with less than 1 year of professional experience are observed while completing an industry sponsored mechanical engineering capstone design project across a 17 week semester. Factors investigated include what CAD tools are used, when in the design process they are implemented, the justification for their use from the students' perspectives, the actual knowledge gained from their use, the impact on the final designed artifact, and the contributions of any sketches generated. At each design step, comparisons are made between CAD and sketching. The students implemented CAD tools at the onset of the project, generally failing to realize gains in design efficiency or effectiveness in the early conceptual phases of the design process. As the design became more concrete, the team was able to recognize clear gains in both efficiency and effectiveness through the use of computer assisted design programs. This study is augmented by interviews with novice and experienced industry users and academic instructors to align the trends observed in the case study with industry practice and educational emphasis. A disconnect in the perceived capability of CAD tools was found between novice and experienced user groups. Opinions on the importance of sketching skills differed between novice educators and novice industry professionals, suggesting that there is a change of opinion as to the importance of sketching formed when recent graduates transition from academia to industry. The results suggest that there is a need to emphasize the importance of sketching and a deeper understanding as to the true utility of CAD tools at each stage of the design process.

The University

This paper addresses the importance of integrating Computer Aided Engineering (CAE) software and applications in the mechanical engineering curriculum. Computer aided engineering tools described include Computer-Aided Design, Computer-Aided Manufacturing, and Computer-Aided Analysis tools such as finite element (FE) modeling and analysis. The integration of CAE software tools in the curriculum is important for three primary reasons: it helps students understand fundamental engineering principles by providing an interactive and visual representation of concepts, it provides students an opportunity to explore their creative ideas and designs while keeping prototyping costs to a minimum, and it teaches students the valuable skill of more efficiently designing, manufacturing and analyzing their products with current technology making them more marketable for their future engineering careers. While CAE has been used in the classroom for decades, the mechanical engineering program at the University of North Florida is making an aggressive effort in preparing the future engineering workforce through computer-aided project-centered education. The CAE component of this effort includes using CAE software when teaching stress, strain, dynamics, kinematics, vibrations, finite element modeling and analysis, design and design for manufacturing, manufacturing and technical communication concepts. This paper describes CAE projects undertaken in several of the mechanical engineering courses at UNF in an effort to share creative teaching techniques for others to emulate.

Since 1998 the author has been developing and teaching computer aided design and computer aided engineering courses intended for mechanical engineering students using the Pro/ENGINEER and I-DEAS software systems. An outline of one of these courses is given and the experience related to another such course is discussed in detail. Students find these courses challenging and enjoyable. The success rate has regularly been very high. By taking such CAD/CAE courses and learning these widely used industry-standard, high-end software systems the students gain valuable experience directly applicable as they join the workforce. The participating students have regularly rated these courses among the most popular ones. The paper discusses the author’s experiences in developing and teaching courses in CAD and CAE, which utilize high-end software. It is intended to provide two examples of successful blends of theoretical and practical topics that have worked very well.
