DU THE GATEWAY COALITION Tele-Manufacturing In Concurrent Engineering-A Course Module Course Description: This course will introduce a new concept and methodology-Concurrent Engineering (CE) into design and manufacturing curriculum. A latest technology, Telemanufacturing in CE, which integrates 3-D solid modeling, CAD/CAM, Rapid prototyping, Telecommunication and networking into an intelligent manufacturing process system, will be taught systematically. A comprehensive application project (example) ‘Design and Manufacturing of a Race Car Spindle’ will be illustrated to further understand Telemanufacturing in CE. Course Length: This is a two hour lecture, three hour reading and two hour homework course module.

DU THE GATEWAY COALITION What is...?

DU THE GATEWAY COALITION CONCURRENT ENGINEERING Definition: Simultaneous or parallel consideration of all facets of the product development process (including design, analysis, manufacturing, testing, quality control and marketing) for the purpose of reducing the time to market, cutting down cost, and improving quality.

DU THE GATEWAY COALITION SEQUENTIAL AND PARALLEL ENGINEERING

DU THE GATEWAY COALITION BENEFITS FROM CONCURRENT ENGINEERING Surveys shows that Concurrent Engineering can reduce the time to market 55%, return on assets 70% higher, and improve overall quality 350% higher

DU THE GATEWAY COALITION CONCURRENT EDUCATION Definition: Concurrently introducing latest science and technology into the new curriculum development of our high education system, breaking the barriers of traditional sequential (i.e.. step by step) and isolated curricula, but integrating multi-stages of curricula and interdisciplinary teachings into classroom.

DU THE GATEWAY COALITION BEST PRACTICE IN CE To better prepare our engineers and to enhance global competitiveness of U.S. industry, the industry’s top 20 “Best Practices” skills should be taught at U.S. universities. Concurrent Engineering integrates the most technologies and skills of the top 20 Best Practice and is an ideal course to train our new generation of engineers.

DU THE GATEWAY COALITION TELE-MANUFACTURING IN CONCURRENT ENGINEERING Today’s manufacturing is not only parallel processes, but also a global activity. Taking the advantages of computer networking and telecommunication, a global range tele- manufacturing is possible. Boeing 777 is a good example of CE and Tele- manufacturing. More than 10,000 people and 200 design groups were involved in the creation of the new plane, which is assembled with four million parts provided from all over the world,

DU THE GATEWAY COALITION How to Create an STL File and File Compression HOW TO CREATE AN STL FILE 1. Create solid model in Master Modeler; 2. Change to Rapid Prototype task; 3. Pick Create Prototype command icon; 4. Pick the part you want to prototype (a Create Prototype form will show up); 5. Select an appropriate Prototype Device; 6. Select Part Positioning to Center; 7. Name Output File and path (If no path is specified, it will be in your current working directory); 8. Type in appropriate value for Absolute Facet Deviation; 9. Pick Show Facets button to see the facets under current setting; 10. Change settings if there is any error message in the last step; 11. Pick OK or Apply button, the stl file with an extension “.stl” will be created. FILE COMPRESSION To compress a file, at UNIX prompt, type compress filename(s), or compress -v filename(s), which will display the percentage of reduction for each compressed file. To decompress a file, type uncompress filename(s).

After trials and errors, the final G-code was FTPed to SUNY Farmingdale in New York, and then a aluminum spindle was manufactured using their CNC machining center in 1.5 hrs.

DU THE GATEWAY COALITION CONCLUSION Concurrent Engineering as a new methodology and also a new technology has been applied in our teaching and research. Concurrent Education as a new concept has been introduced to our curriculum reformation. As an example, a research project entitled “Design and Manufacturing of a Rear Wheel Spindle and its Assembly for the FSAE Race Car” was conducted by using CE and concurrent education, which resulted in saving time (five weeks student’s school time was used), higher quality (a safety factor ten was obtained from FEA), reducing the cost (the cost reduced from $ to $50.31 per part), and the most importantly trained a new generation of CE force.
